{"id":"c159b976-18e5-4f2a-90c8-113f92729c3f","shortId":"QbZGdd","kind":"x402","title":"HIPAA health records endpoint payable per-request via x402 on Base (USDC).","tagline":"HIPAA health records endpoint payable per-request via x402 on Base (USDC).","description":"This endpoint at lowpaymentfee.com provides access to HIPAA-related health records via a pay-per-call x402 protocol. The specific resource `/api/v1/hipaa/records/81` is accessed via HTTP POST and costs $0.02 per request, settled in USDC on the Base network. 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 endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of APIs across categories including data analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced uniformly at $0.02 per request. The x402 challenge confirms the endpoint is live, accepting the \"exact\" payment scheme with a max amount of 20,000 base units of USDC (6 decimals = $0.02). Payment is directed to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 on Base.\n\nDocumentation is extremely sparse. The crawled /docs, /api, /pricing, and /README pages all returned only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI spec, no request/response schema documentation, and no description of what data the HIPAA records endpoint actually returns. The endpoint name suggests health-related data, but the exact payload structure, required POST body fields, and response format are unknown. Callers should exercise caution given the HIPAA labeling — it is unclear whether this endpoint handles real protected health information or is a demonstration/placeholder.","tags":[],"capabilities":["x402-payment","per-request-billing","usdc-settlement","base-network","hipaa-records","http-post","no-api-key","no-rate-limit"],"categories":["health","data"],"synonyms":["HIPAA API","health records API","medical records endpoint","x402 health data","pay-per-call HIPAA","Base USDC API","lowpaymentfee HIPAA"],"warnings":["No API documentation available — /docs, /api, /pricing, /README all return only 'Connect wallet' with no content","No request body schema or response schema documented; callers cannot know what to send or expect back","Endpoint is labeled 'HIPAA records' which implies regulated health data — no compliance documentation, BAA information, or privacy policy was found","The nature of the data returned is completely unknown; this may be a placeholder or demonstration endpoint"],"endpointUrl":"https://lowpaymentfee.com/api/v1/hipaa/records/81","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/81","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The x402 challenge is live and confirms pricing and payment details, but there is zero documentation on request/response schemas, no OpenAPI spec, and the crawled doc pages are empty.
