OSF Entity Lookup (CMS NPI, GLEIF LEI, FDIC, SEC EDGAR)
Entity and counterparty verification by identifier or name. Resolves against authoritative public registries: US healthcare providers (CMS NPI), global legal entities (GLEIF LEI), US insured banks (FDIC), and SEC filers and public companies (EDGAR CIK). Pass an identifier (NPI, LEI, FDIC cert, or CIK) for an exact match, or a name for candidate matches. Returns legal name, status, type, jurisdiction, key identifiers, and a provenance URL to the official source, plus a hashed audit receipt. $0.01 USDC per lookup on Base. For KYC, KYB, counterparty due diligence, provider verification, and onboarding agent workflows.
Start with a quote-only recipe. Payment signing stays in your project.
const response = await fetch("https://api.osf-master-server.com/x402/identity/entity/:query", {

});
console.log(response.status);
console.log(Object.fromEntries(response.headers));
console.log((await response.text()).slice(0, 1000));
// A valid 402 is a quote, not a completed paid call.This sends no payment. Inspect the 402 response before adding a wallet-enabled client.

EVIDENCE
Each record has an exact-route quote outcome. Unresolved templates and potentially mutating methods are labeled instead of being invoked without provider-specific test input. A quote is still separate from a settled paid call.
