The specific resource `/api/v1/hipaa/records/47` is accessed via POST and returns JSON. Payment is settled in USDC on the Base network at $0.02 per request (20,000 base units of USDC with 6 decimals). No API keys, rate limits, or upfront commitments are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.\n\nThe provider, lowpaymentfee.com, hosts a broad catalog of x402-gated APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities, all priced uniformly at $0.02 per request. This particular endpoint falls under a \"HIPAA records\" path, but the crawled documentation is extremely sparse — the docs, pricing, API, and README pages all render only a \"Connect wallet\" prompt with no further detail. There is no OpenAPI spec, no request/response schema documentation, and no description of what fields the HIPAA records endpoint accepts or returns.\n\nBecause the endpoint path references HIPAA (Health Insurance Portability and Accountability Act) data, callers should exercise caution: there is no visible evidence of HIPAA compliance certifications, BAA (Business Associate Agreement) availability, or any privacy/security documentation on the site. The endpoint is confirmed live (returns a proper 402 challenge), but the lack of documentation makes it impossible to verify what data is actually served or what input is expected.","tags":[],"capabilities":["x402-payment","per-request-billing","usdc-base-network","hipaa-records","json-response","post-method"],"categories":["health","data"],"synonyms":["HIPAA API","health records API","medical records endpoint","x402 health data","pay-per-call HIPAA","lowpaymentfee HIPAA"],"warnings":["No OpenAPI spec or request/response schema available — input and output formats are unknown","Endpoint claims to serve HIPAA records but no HIPAA compliance documentation, certifications, or BAA information is visible on the site","All documentation pages (docs, pricing, API, README) render only 'Connect wallet' with no content","Regulated health data category — callers should verify legal and compliance requirements independently","The specific record ID '47' in the path is hardcoded; it is unclear how to query other records"],"endpointUrl":"https://lowpaymentfee.com/api/v1/hipaa/records/47","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://lowpaymentfee.com/api/v1/hipaa/records/47","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is confirmed live with a valid 402 challenge and clear pricing ($0.02 USDC on Base), but there is zero documentation on request format, response schema, or what data is actually returned.
