The specific resource `/api/v1/hipaa/records/26` is labeled \"Premium API Access\" and accepts POST requests, settling payments in USDC on the Base network. The price per request is $0.02 (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 broader lowpaymentfee.com platform hosts a variety of x402-gated APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request. However, this specific listing covers the HIPAA records endpoint. The endpoint returns application/json and is discoverable via the x402 challenge. Documentation on the site is extremely thin — the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no further technical detail.\n\nBecause the endpoint is described as serving HIPAA records, callers should be aware this falls in a regulated health-data category. There is no published OpenAPI schema, no request/response examples, and no documentation explaining what fields the POST body expects or what the response contains. The actual data served and its compliance posture are unknown from the available material.","tags":[],"capabilities":["x402-payment","hipaa-records","usdc-base-settlement","pay-per-request","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":["HIPAA / health data category — no compliance documentation or certifications are provided by the site","No request body schema documented; callers cannot know what fields to send","No response schema or example; actual data returned is unknown","All documentation pages (docs, API, pricing, README) render only 'Connect wallet' with no content","Regulated health data: verify legal and compliance requirements before use in production"],"endpointUrl":"https://lowpaymentfee.com/api/v1/hipaa/records/26","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/26","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is zero documentation on request/response schemas, no OpenAPI spec, no examples, and the HIPAA label raises regulatory concerns with no compliance evidence.
