serviceName: address-poison-check

description: Before sending funds, check if the recipient is an address-poisoning look-alike. Give us the recipient and your known/intended addresses; we flag when the recipient shares the displayed head AND tail of one you know but differs in the middle — the exact signature of a poisoning attack that fools copy-paste. Deterministic, no LLM, no external calls. Answers an agent's question 'is this really the address I mean?'


serviceName: approval-risk

description: Audit standing ERC-20/Permit2 approvals for danger. Raw allowance lookups exist elsewhere; this is the risk layer: pass your current approvals and we rank which to revoke — unlimited allowance, unknown (non-registry) spender, or the classic drainer pattern (unlimited AND unknown). Deterministic, no LLM, no external calls. Answers an agent's question 'which of my approvals are dangerous?'


description: Why is my x402 service not listed in the Bazaar? Give us your endpoint URL; we fetch your 402 envelope, run the exact SDK validation and extraction functions the CDP facilitator runs, check catalog presence, and return per-check pass/fail with concrete fix hints — including the undocumented requirement that a buyer must echo your bazaar extension into the settle payload. Deterministic, no LLM.

key: POST https://x402.fuchss.app/v1/similar

description: Find better alternatives to an x402 endpoint. Given a resource URL, returns the top semantically-similar endpoints (matched on advertised purpose via description embeddings) that currently OUT-SCORE it on our deterministic trust score — so an agent about to pay a mediocre endpoint can discover a more reliable, better-settled one serving the same function. Each result carries its trust score, grade, cosine similarity, advertised price and free endpoint-page URL. Same-host siblings and 'avoid'-flagged endpoints are excluded. Returns an empty list (still a valid answer) when nothing beats the subject.


description: Monitor ONE x402 endpoint for 30 days and get alerted on changes that break agents: payTo changes (critical — possible takeover/rug), price changes, asset/network changes, 402-spec regressions, delisting, and liveness (down/recovered). Account-free: pay, receive a one-time secret + poll URL. Push to multiple signed HTTPS webhooks and/or Slack/Discord incoming webhooks (up to 5 each per watch). Every push URL is connection-tested before payment — unreachable URLs are rejected with no charge. Edit URLs or cancel early for free via bearer-authed PATCH/DELETE /v1/watch/{id}. Poll the append-only event log; nothing is lost between polls.


description: Raw observation history for any publicly listed x402 endpoint: discovery snapshots (listed/delisted/relisted, price changes, payTo changes) and probe time-series (uptime, latency, quoted amount) over the requested window (1-90 days).


description: Trust score (0-100, grade A-F) for any publicly listed x402 endpoint. Unlike uptime-only checkers, we return ECONOMIC PROOF: the REAL on-chain USDC settlement volume and distinct-payer count for the endpoint's payTo address — is anyone actually paying it, or is it just live? Computed deterministically from continuous monitoring: 30d probe uptime, 402-envelope spec compliance, latency, observed age, on-chain settlement activity, and advertised-price stability. Includes a full component breakdown, machine-readable flags, and an honest observedDays (we report only the history we actually have, with dataCompleteSince marking our gap-free on-chain coverage). Know before you pay.


description: Score up to 10 x402 endpoints in a single paid call. Each found result carries the FULL trust report — identical to POST /v1/x402-trust: score, grade, scoreRange, recommendation, confidence breakdown, the component/subscore breakdown, explanations, flags + flagsDetailed, advertised price, and 30-day on-chain stats — not just the scalar verdict. Cache rows older than 15 minutes are recomputed on-demand from the latest stored probes and settlements, so scores typically reflect reality within minutes. No live network re-probe is performed — for a fresh live probe use /v1/x402-trust. Per-request recompute limits apply (time + count); results include `recomputed` and `computed_at` so you can see which rows used cached vs freshly computed scores. Resources not in our observation set return `foun

description: Create a Solana associated token account (ATA) for a given Solana wallet and SPL mint, paid via Base USDC. Typical use: prepare a Solana wallet to receive USDC or other SPL tokens before sending funds or using bridge flows. Cost: 0.4 USDC per call, paid on Base.

Optional max_input_tokens lets you cap the input tokens used for pricing; if the message is longer than this cap the server returns an error instead of under-pricing. Optional action=message (or omitting action) performs a direct GPT call with the given message. Optional action=create creates a custom agent with the given message as preprompt for 0.001 USDC (no OpenAI call), stores a base_price_usdc using (max_input

Give it an x402 endpoint_url (or a payTo address) and it returns, in one cheap deterministic call: is the resource reachable, is it present in the CDP Bazaar discovery catalog (serviceName, declared payTo, price, network, tags, last_seen), and — the key integrity check — does the payTo the endpoint actually demands in its live HTTP 402 challenge MATCH the payTo the catalog advertises (payTo_match). It runs a keyless HEAD/OPTIONS/402 probe that never moves funds, extracts the real payTo/amount/asset/network from the challenge, scores listing freshness, and — if you pass a prev snapshot {payTo,amount,lastUpdated} — flags whether the endpoint changed since you last saw it (anti-rug).
