Unknown hash returns 404. Sibling of /api/crypto/gas-oracle (fees) and /api/crypto/address-validate (format).


key: GET https://2s.io/api/crypto/vrf

description: Verifiable random function — deterministic, publicly verifiable randomness bound to your seed and signed by the 2s key. proof = deterministic EIP-191 signature over the seed (same seed always yields the same proof, so the outcome cannot be re-rolled or cherry-picked); random = keccak256(proof), a uniform 32-byte value.

Omit categoryId (or pass 0) for the eight top-level categories: Money/Banking/Finance, Population/Employment/Labor, National Accounts, Production & Business Activity, Prices, International Data, U.S. Regional Data, Academic Data. Walk down via each child's id. Free, public-domain (FRED). The structured map of what FRED actually contains — far more reliable than guessing series ids.

Also returns the series' vintage (revision) dates — every date the series was revised. Free, public-domain (FRED). Critical for honest backtesting and macro research: it eliminates look-ahead bias (e.g. GDP for 2020Q1 was first reported far lower than today's revised figure). No LLM and no real-time API gives this — it's the archived state of the data through time. Pair with econ.fred (current series) and econ.fred-releases (release calendar).

key: GET https://2s.io/api/edu/school-lookup

description: Look up any US public K-12 school (~102k, NCES Common Core of Data). Search by name (partial), district (LEA name, partial), state (2-letter), city, zip, or exact ncessch (12-digit NCES id). Each school: NCES id, name, district + LEA id, address, phone, lat/lon, school level (1=primary 2=middle 3=high 4=other) and type (1=regular 2=special-ed 3=vocational 4=alternative), charter/magnet/virtual flags, enrollment, teacher FTE, grade span, CCD year. Results ordered by enrollment. Higher-ed sibling: /api/edu/college-scorecard. Public-domain federal data.


key: GET https://2s.io/api/email/validate

description: Validate an email address and return structured signals: RFC syntax validity (isSyntaxValid + reason if not), the normalized address with split local/domain, and boolean flags for isDisposable (throwaway/temp-mail domain), isRoleAccount (info@, support@, admin@, …), and isFreeProvider (gmail/outlook/yahoo/icloud/…). With checkMx (default true) it also reports hasMxRecords — whether the domain publishes MX records, looked up live via DNS-over-HTTPS — plus the MX hosts. IMPORTANT: this is NOT a deliverability or mailbox-existence guarantee (catch-all domains, greylisting, and privacy relays make that impossible to assert from a single lookup); hasMxRecords reflects DNS MX presence only. Useful for signup-flow hygiene, lead scrubbing, and flagging disposable/role addresses before sending.


description: Retail electricity price and sales for a US state by customer sector (residential, commercial, industrial, transportation, all), monthly, newest first, from EIA. Returns average price (cents/kWh), sales (MWh), revenue ($M), and customer count per month. Public-domain, live-wrap. More granular than energy.prices (which is the national all-sector benchmark only).


description: Locate alternative-fuel stations across the US via NREL Alternative Fuels Data Center. Search by lat/lon + radius (miles), state, or zip. Filter by fuelType (BD=Biodiesel | CNG=Compressed Natural Gas | ELEC=Electric vehicle charging | E85=Ethanol | HY=Hydrogen | LNG=Liquefied Natural Gas | LPG=Propane | RD=Renewable Diesel), status (E=Available | P=Planned | T=Temporarily Unavailable), access (public/private), and EV network. For EV chargers, returns connector types (J1772, CHAdeMO, Tesla, etc.), Level 1/2/DC-fast counts, pricing, and access hours. Indispensable for trip-planning agents, fleet logistics, EV-adoption analysis.


description: Electricity generation mix by fuel type for a US state (2-letter) or "US", from EIA — the most recent monthly net generation (thousand MWh) broken out by fuel (natural gas, coal, nuclear, solar, wind, hydro, etc.) with each fuel's percent share and the all-fuels total. Public-domain, live-wrap. Use for grid carbon-intensity, decarbonization, and energy-policy reasoning. (For benchmark energy prices use energy.prices; for retail electricity rates by state/sector use energy.electricity-rates.)


key: GET https://2s.io/api/energy/prices

description: US energy benchmark prices from the EIA (Energy Information Administration) open data API. Omit series for a one-call snapshot of the latest value of every benchmark; pass series for its recent time series (newest first). Benchmarks: wti_crude / brent_crude ($/barrel), henry_hub_gas ($/MMBtu), gasoline_regular / diesel ($/gallon), electricity_retail (cents/kWh). Each observation has date, value, units, and frequency.

Sourced from NREL National Solar Radiation Database (NSRDB). Useful for rooftop solar feasibility, off-grid design, and renewable-energy modeling.


description: Which electric utility serves a US latitude/longitude, and a summary of its published rate plans, from the OpenEI Utility Rate Database (URDB, CC0). Each plan returns the utility, rate name, customer sector, EIA utility id, fixed monthly charge, the first-tier energy rate ($/kWh), and a link to the full tariff. Use for solar/EV/storage economics, bill estimation, and "who is my utility" lookups. (For average state retail prices use energy.electricity-rates.)


key: GET https://2s.io/api/factcheck/search

description: Search the global corpus of published fact-checks (ClaimReview) by free-text claim. Returns matching claims with the claimant, claim date, and each fact-check review's verdict (textualRating, e.g. "False", "Misleading", "True"), the publisher (PolitiFact, Snopes, FactCheck.org, Reuters Fact Check, AFP, …), the review URL, and review date. Covers every topic — politics, health, science, viral and misinformation claims. Optional language, recency (maxAgeDays), and publisher-site filters. Aggregated by Google from publishers' schema.org ClaimReview data. Use it to check whether a claim has been independently fact-checked and how it was rated, rather than asserting from training data.


key: GET https://2s.io/api/finance/amortize

description: Compute a loan or mortgage amortization schedule. Pass principal, annualRatePct (e.g. 6.5), and the term as termMonths or termYears; optional extraMonthly adds extra principal each month (shortening the term). Returns the fixed monthly payment, total interest, total paid, the actual payoff month count, and the full month-by-month schedule (each row: payment, principal, interest, remaining balance). Handles the 0% case and trims the final payment exactly. Deterministic — the ground-truth answer for a loan/mortgage/auto-finance question instead of an LLM approximating compound interest. No external calls.


description: Resolve a bank / financial institution across identifier systems. Give exactly one of bic (SWIFT/BIC), lei, or fdic_cert and get the others back: LEI, every ISO 9362 BIC the institution registers, the FDIC institution record (when matched), jurisdiction, and a canonical name. The BIC<->LEI bridge is authoritative and live from GLEIF (the LEI record carries the institution BIC list, CC0); anchoring on an FDIC certificate returns the FDIC BankFind record and best-effort name-matches it to a GLEIF LEI (flagged via bridge). There is no free FDIC-cert<->BIC table, so the FDIC<->GLEIF link is name-match only -- per-source status + bridge make any partial resolve explicit. Sources: GLEIF (CC0) + FDIC BankFind (US public domain).


key: GET https://2s.io/api/finance/bin

description: Identify a payment card from its BIN/IIN (Bank Identification Number — the leading 6-8 digits). Pass the BIN or the first digits of a card number and get the card brand (Visa, Mastercard, …), card type (debit/credit), category, issuing bank, and country (ISO alpha-2 + name). Longest-prefix match against an open community dataset (CC-BY). The BIN identifies the issuer/brand/country only — never the cardholder or account number. For payment routing, fraud checks, and checkout UX.


description: Headline central-bank policy/benchmark rates side-by-side in one call, normalized: US (Fed effective funds rate), Euro area (ECB deposit facility rate), Japan (BoJ call-money benchmark), United Kingdom (SONIA, which tracks the BoE Bank Rate). Each result names the bank, country, the rate, the as-of date, the FRED series id, and a label stating exactly which instrument it is (banks don't all publish the same policy instrument). Pass bank to filter (one of: fed, ecb, boj, boe), or omit for all. Source: FRED (St. Louis Fed).


description: Resolve SEC CIK <-> ticker in both directions. Pass a ticker to get its CIK; pass a CIK to get every ticker the issuer has (each share class, e.g. GOOG + GOOGL), each with its listing exchange (Nasdaq, NYSE, etc.) and the canonical company name. The CIK is the key to everything in EDGAR -- filings, XBRL facts, Form 4 insider trades, 13F holdings -- so this is the join that turns a ticker an agent has into the identifier EDGAR actually indexes by (and back). Data: SEC company_tickers_exchange.json (US public domain), cached and refreshed daily. Distinct from finance.security-resolve, which also crosses into FIGI/LEI/ISIN; this one is the focused, exchange-aware CIK<->ticker map.


description: Curated XBRL financial metrics for a US public company by stock ticker. Pulls SEC EDGAR's companyfacts JSON (per-CIK XBRL filings) and extracts a top-line set of ~15 financial metrics with their most recent annual + quarterly values. Each metric returns: end date, start date (or null for balance-sheet snapshots), value, fiscal year/period, originating form (10-K/10-Q), and filed date. Available metric keys (pass any comma-separated subset via the metrics param, or omit to get all): revenue, grossProfit, operatingIncome, netIncome, eps, epsDiluted, rdExpense, totalAssets, totalLiabilities, stockholdersEquity, cash, longTermDebt, operatingCashFlow, capex, sharesOutstanding. Backed by SEC.gov; underlying data is public-domain US government records.


description: Company 360 — a US public company's SEC picture in one call by ticker. Merges three SEC sources: recent filings (10-K/10-Q/8-K and all form types, with links), curated XBRL fundamentals (revenue, net income, EPS, assets, etc. — annual + quarterly series), and recent insider transactions (Form 4 buys/sells by officers & directors). Each section reports found/error independently. Equity research, due diligence, monitoring. Pass ticker (required); optional formType filters the filings section, limit caps each list. Individual sources: /api/finance/sec-filings, /api/finance/company-facts, /api/finance/insider-trades.


key: GET https://2s.io/api/finance/figi

description: Map a security identifier to its FIGI (Financial Instrument Global Identifier) and metadata via OpenFIGI. Give an idType (ISIN, CUSIP, SEDOL, TICKER, FIGI, COMMON, WKN, CINS — or a raw OpenFIGI ID_* type) and idValue, optionally narrowed by exchCode (e.g. US, LN) or currency. Returns each matching listing with its FIGI, composite FIGI (per-country grouping), share-class FIGI (cross-country grouping), name, ticker, exchange code, security type, market sector, and description. Free, open symbology (Bloomberg OpenFIGI; FIGI is an open OMG/ANNA standard). The canonical "what is this security and what are its identifiers across exchanges" lookup — for trading, reference-data, and portfolio agents.


description: Free-text search for securities across global exchanges via OpenFIGI. Give a query (company name, ticker, description) and optionally narrow by exchCode (e.g. US), securityType, or marketSector (Equity, Corp, Govt, Mtge, Muni, Pfd, Comdty, Index, Curncy). Returns relevance-ranked matches with FIGI, composite/share-class FIGI, name, ticker, exchange, security type, market sector, and description, plus a `next` cursor for paging (pass it back as start). Free, open symbology (Bloomberg OpenFIGI). Distinct from finance.figi (exact identifier → FIGI): this is discovery by name/keyword.


key: GET https://2s.io/api/finance/form-144

description: SEC Form 144 filings — notices of PROPOSED insider stock sales (intent to sell restricted/control shares), newest first, via EDGAR full-text search. Market-wide by default, or filter by ticker/company/keyword (q). Each: filer + issuer names, filing date, accession, CIKs, and a filing URL. The heads-up before a Form 4 confirms the sale. Complements finance.insider-trades.


description: Indian bank branch lookup by IFSC code (the 11-character Indian Financial System Code identifying a bank branch). Returns the bank name and code, branch, centre, district, state, city, full address, contact number, MICR code, and which payment rails the branch supports (IMPS, RTGS, NEFT, UPI). Free, open data (Razorpay / RBI directory). Deterministic bank-branch reference for payments, remittance, and KYC validation in India.


description: Recent SEC Form 4 insider transactions for a US public company by ticker. Returns parsed transactions: insider name + relationship (director, officer/title, 10%+ owner), transaction date, SEC code (P=purchase, S=sale, A=grant, D=disposition, M=exercise, F=tax-withholding, G=gift), security title, shares, price/share, total USD value, post-transaction balance, direct vs indirect ownership. Each filing pulled separately and parsed from raw XML — bounded by limit (1-10, default 5). Backed by SEC.gov; underlying Form 4 filings are public records. For insider trades + filings + fundamentals merged by ticker in one call, see /api/finance/company-profile.


description: Recent SEC EDGAR filings for a US publicly-traded company by stock ticker. Resolves ticker → CIK via SEC's company_tickers.json, then fetches the company's submissions index from data.sec.gov. Returns company metadata (name, CIK, SIC industry classification, exchanges, fiscal year-end, state of incorporation) plus filings with form type, filing date, report date, accession number, primary-document URL, and filing-index URL. Filter to one form type (10-K, 10-Q, 8-K, 4, 13F-HR, SC 13G, S-1, etc.) via formType param. Default 20 results, max 100. Backed by SEC.gov; underlying filings are public-domain US government records. For filings + fundamentals + insider trades merged by ticker in one call, see /api/finance/company-profile.


description: Universal security-identifier resolver. Give exactly one of ticker, isin, or lei and get the others back — ticker, SEC CIK, FIGI (incl. composite + share-class), LEI, and ISINs — plus the canonical issuer name. The one call that joins a security across the systems agents actually use: CIK for filings, FIGI for trading, LEI for the legal entity, ISIN for settlement. Composes SEC EDGAR, OpenFIGI, and GLEIF (CC0). Per-source status is returned, so a partial match is explicit rather than silently wrong. Note: CUSIP/SEDOL are accepted by sibling /finance/figi as inputs but never emitted here (licensed); ISINs come from GLEIF CC0 data.


description: Parsed institutional holdings from a 13F-HR filing. By investment-manager CIK (e.g. 1067983 = Berkshire Hathaway). Returns each holding's nameOfIssuer, cusip, market value (whole USD per the modern Form 13F convention), shares/principal amount + type, putCall flag for options, and voting authority (sole/shared/none). Sorted by value descending. Pass formType for amendments (13F-HR/A) or non-filings (13F-NT). Backed by SEC.gov; underlying 13F filings are public records.


description: SEC EDGAR XBRL Frames — one financial concept reported by every public filer for a single period, for cross-company screening and comparison. Give an XBRL tag (e.g. Revenues, NetIncomeLoss, Assets), a unit (default USD), and a period (CY2023 for annual, CY2023Q1 for a quarter, CY2023Q4I for instant balance-sheet items), and get back every filer's value — company name, CIK, location, period start/end, and the reported value — sorted high to low (or asc). Returns the total filer count and the top N. Free, public-domain (SEC). Distinct from finance.company-facts (one company, many metrics): this is one metric across all companies. For ranking, peer comparison, and market-wide analysis.

Choose the board with type. Real-time operational data for an airport; complements flight.status (single flight) and flight.route-schedule.


description: Scheduled flights between two airports over a date window (FlightAware AeroAPI). Pass origin and destination (ICAO or IATA) plus startDate/endDate; returns scheduled flights with ident, operator, aircraft type, origin/destination, and scheduled departure/arrival times.

Each layer is isolated: one source failing does not fail the rest. This is the slow-moving structural-risk picture (siting, insurance, due diligence), distinct from real-time weather/earthquake conditions.

description: Everything around a coordinate in one call: nearby airports (IATA/ICAO, type, distance), public K-12 schools (name, district, enrollment, distance), NOAA climate stations (for chaining into /api/climate/station-history), and earthquakes from the past week (magnitude, depth, time). Pass lat/lon plus optional radiusKm (default 25, max 200) and per-category limit (default 5). Each category returns an independent found/error block, so one slow source never empties the rest. Site assessment, relocation research, travel planning, and risk screening. Each category is also a standalone endpoint (/api/airport/near, /api/edu/school-lookup, /api/climate/station-near, /api/quakes/recent).


key: GET https://2s.io/api/geo/postal

description: Resolve a postal/ZIP code to its place name(s), administrative divisions, and coordinates. Pass `postalCode` and a 2-letter `country` (default US).

description: Resolve a US ZIP code to the census tract(s), county, CBSA (metro), and congressional district it covers — each with HUD-USPS allocation ratios (by residential, business, other, and total address counts). A ZIP is a mail-delivery route set, not a polygon, so it spans multiple geographies; the ratios tell you how much of the ZIP falls in each — the canonical join when you have a ZIP but a dataset is keyed by county/tract/district. Source: HUD-USPS ZIP Crosswalk (public domain).

Pass congress + type + number to fetch a specific bill (title, sponsors, latest action, action/amendment/committee counts, policy area, congress.gov URL). Or omit number to list bills filtered by congress, bill type (hr | s | hjres | sjres | hconres | sconres | hres | sres), date range, with pagination + sort. Bill type semantics: hr=House Bill, s=Senate Bill, hjres/sjres=joint resolution, hconres/sconres=concurrent resolution, hres/sres=simple resolution.


description: List or look up US Congressional committees (Library of Congress Congress.gov). Pass systemCode (e.g. "hspw00") to fetch a single committee with full detail (members, subcommittees, history, hearings, jurisdiction). Or filter list by congress + chamber (house | senate | joint). Standard system codes follow chamber prefix + abbreviation + suffix convention.


description: Track US House members' financial-disclosure filings — including Periodic Transaction Reports (PTRs), the STOCK Act filings where members must disclose their stock trades within 45 days. Defaults to PTRs; pass type=annual|candidate|amendment|all to see other disclosure kinds. Filter by member name (q), 2-letter state, filing year, or filing-date range (dateFrom/dateTo). Each result gives the member, state + district, filing type (with a readable label), the filing/disclosure date, and a direct link to the source document (docUrl). The envelope total is the full count matching your filter — so q=Pelosi or year=2026 answers 'how many PTRs did they file'. Covers 2008→present (~8,200 PTRs), refreshed daily so new filings appear within ~a day. Note: by law trades are disclosed up to 45 days aft


description: Look up or list US Congressional hearings via Congress.gov. Pass congress + chamber + jacketNumber to fetch a single hearing with full detail (title, dates, committee, transcripts/recordings if available). Or filter list by congress + chamber, with optional date range. Hearings cover committee testimony from the executive branch, subject experts, and stakeholders — primary-source material for oversight + policy research.


description: Look up or search members of the US Congress via Library of Congress Congress.gov API. Pass bioguideId (e.g. M001190) to fetch one member (full bio, terms, party history, leadership roles, sponsored + cosponsored legislation counts, official website, address). Or filter by congress + state + district, with currentMember=true to limit to seated members. Bioguide IDs are stable across history and are the canonical Congress-member identifier.


description: Look up or list US presidential nominations (cabinet, judicial, executive) sent to the Senate for confirmation via Congress.gov. Pass congress + number for a single nomination with full action history. Or filter list by congress + date range. Each row carries: citation (PN###-#), description (nominee + position), receivedDate, nominationType (civilian / military / etc.), organization, latest action (committee referral, hearing, confirmation, withdrawal). Essential for confirmation-tracking + judicial-vetting agents.


description: List daily Congressional Record issues via Congress.gov — the official transcripts and proceedings of the US House and Senate, daily. Filter by year + month + day to narrow to a specific date or month. Each issue carries volume, issue number, publish date, and links to per-section content (Daily Digest, Senate, House, Extensions of Remarks) with PDF + sub-section URLs. Primary source for what was said on the floor.


description: Search individual US Congress member stock trades, parsed from STOCK Act Periodic Transaction Reports into clean rows. Filter by member name (q, e.g. "Pelosi"), ticker (e.g. NVDA), transaction type (purchase | sale | exchange | partial_sale), 2-letter state, chamber, or transaction-date range (dateFrom/dateTo). Each trade returns the member + state/district, owner (self/spouse/joint/dependent), ticker + asset description, buy/sell, the disclosed dollar RANGE (amountMin/amountMax — disclosures are ranges, not exact), the transaction date, the disclosure date, days-to-disclose (compliance lag), and a link to the source filing PDF. The envelope total is the full count matching your filter — so ticker=NVDA&type=purchase counts who bought NVIDIA. Amounts are ranges by law; trades are disclosed


description: Look up or list international treaties transmitted to the US Senate for advice and consent via Congress.gov. Pass congress + number (optionally + suffix for partitioned treaties) to fetch a single treaty with parties, topic, transmittal date, and consideration status. Or list by congress. Returns the congress the treaty was received in, the congress that considered it (if any), partial-treaty suffix, topic, transmitted date, and count of parties.


key: GET https://2s.io/api/gov/counterparty

description: Federal counterparty due-diligence dossier on one name, in a single call. Give name (a company or person) and optional state; get back six independent federal/authoritative screens composed into one verdict: SAM.gov registration (UEI/CAGE, active status), SAM federal exclusions (debarment/suspension), OFAC SDN sanctions, GLEIF Legal Entity Identifier, USAspending federal contract-award history, and FARA foreign-agent registration. Returns headline riskFlags (e.g. federally_debarred, sanctions_high_confidence_match, registered_foreign_agent), a cleared boolean (true only when both debarment AND sanctions sources answered and were clean — FARA status is disclosure context and does NOT affect cleared), a summary of booleans, and a per-source found/error/data block so one slow or empty source


key: GET https://2s.io/api/gov/district

description: Resolve a US street address to its congressional district (119th Congress), state, and county, via the US Census Bureau geocoder. Returns the matched/normalized address, latitude/longitude, state (name + 2-letter abbreviation), county, and the district number within the state (null for at-large or non-voting delegate districts). The point-in-polygon district lookup is something an agent can't do from a sandbox. Pair it with the gov/congress.* endpoints to find the representatives once you have the state + district. Public domain, keyless.


key: GET https://2s.io/api/gov/entity

description: Look up entities registered to do business with the US federal government in SAM.gov. Search by ueiSAM (12-char Unique Entity ID), cageCode, or legalBusinessName (provide at least one); page with limit (1-100). Returns each entity with its UEI, CAGE code, legal and DBA name, SAM registration status and dates (registration, expiration, last update), purpose of registration, an active-exclusion flag, physical address, and business types — plus a total match count. Data: SAM.gov entity management, free and public-domain (registration core data; sensitive FOUO sections are not returned). The canonical federal counterparty identity key — pair with /api/gov/exclusions (debarment) and /api/law/sanctions-check (OFAC) for full counterparty due diligence.
