The specific resource `/api/v1/hipaa/records/99` returns JSON data when a valid X-PAYMENT header is supplied. Payment is settled in USDC on the Base network.\n\nThe endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. However, this particular HIPAA records endpoint advertises a maxAmountRequired of 20,000 base units of USDC (6 decimals), which equals $0.02 — consistent with the site-wide pricing.\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 beyond the x402 challenge's outputSchema stub, and no description of what fields the HIPAA records response contains. The endpoint is live (returns a proper 402 challenge), but the lack of documentation makes it difficult to know what data is actually returned or what input the POST body expects. The HIPAA label raises regulatory concerns — callers should verify compliance before use.","tags":[],"capabilities":["x402-payment","usdc-base","hipaa-records","per-request-pricing","no-api-key","json-response"],"categories":["health","data"],"synonyms":["HIPAA API","health records API","medical records endpoint","x402 health data","pay-per-call HIPAA","Base USDC health API"],"warnings":["No API documentation available — /docs, /api, /pricing, and /README all return only a wallet-connect prompt","No request body schema or response schema documented; callers cannot know what to send or what they will receive","Endpoint is labeled 'HIPAA' but no compliance certifications, BAA information, or regulatory documentation is provided","The specific record ID '99' is hardcoded in the URL — unclear if this is a demo or a real record identifier"],"endpointUrl":"https://lowpaymentfee.com/api/v1/hipaa/records/99","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/99","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, confirming it accepts USDC on Base at $0.02 per call.
