The specific resource `/api/v1/hipaa/records/52` is described as \"Premium API Access\" and accepts POST requests. 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 or rate limits 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 pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced uniformly at $0.02 per call. However, the specific HIPAA records endpoint is not listed on the provider's public landing page among the advertised API categories. The endpoint is live and returns a proper 402 challenge, but there is no documentation describing the request body schema, expected response format, or what data the HIPAA records resource actually returns.\n\nBecause this endpoint claims to serve HIPAA-regulated health records, callers should exercise caution. There is no visible documentation about HIPAA compliance, BAA (Business Associate Agreement) availability, data provenance, or privacy safeguards. The crawled docs, pricing, and README pages all returned only a \"Connect wallet\" stub with no substantive content.","tags":[],"capabilities":["x402-payment","usdc-base","hipaa-records","pay-per-request","no-api-key","post-endpoint"],"categories":["health","data"],"synonyms":["HIPAA API","health records API","medical records endpoint","x402 health data","pay-per-call HIPAA","Base USDC health API"],"warnings":["HIPAA-regulated health data: no documentation of compliance, BAA, or data provenance found","This specific endpoint (/api/v1/hipaa/records/52) is not listed among the provider's publicly advertised APIs","All documentation pages (docs, pricing, README, api) returned only 'Connect wallet' with no content","No request body schema or response schema available — callers cannot know what to send or expect back","Regulated health data category — verify legal and compliance requirements before use"],"endpointUrl":"https://lowpaymentfee.com/api/v1/hipaa/records/52","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/52","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live and returns a valid x402 402 challenge, but there is zero documentation on request/response schema, no OpenAPI spec, and the HIPAA records endpoint is not even listed on the provider's own landing page.
