The specific resource `/api/v1/hipaa/records/13` 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, crypto, and utility services, all priced uniformly at $0.02 per call. However, the specific HIPAA records endpoint is notable because it implies access to health-related data, which falls under regulated categories. No documentation beyond the landing page listing was available — the /docs, /api, /pricing, and /README pages all returned only a \"Connect wallet\" prompt with no substantive content.\n\nBecause no request/response schema, sample payloads, or detailed documentation were found, the actual data returned by this endpoint is unknown. The endpoint is confirmed live (returns a proper 402 x402 challenge), but callers should exercise caution given the HIPAA labeling and complete lack of documentation about what data is served or how it is sourced.","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-labeled endpoint with no documentation on data provenance, compliance, or actual content returned","No request or response schema available — callers have no way to know what to send or what they will receive","All documentation pages (/docs, /api, /pricing, /README) are empty beyond a wallet connect prompt","Regulated health data category — verify compliance independently before use in any production context","The specific record ID '13' in the URL is hardcoded; unclear if other record IDs are available or what they represent"],"endpointUrl":"https://lowpaymentfee.com/api/v1/hipaa/records/13","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/13","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is live and returns a valid x402 challenge, but there is zero documentation on request format, response schema, or what data is actually returned.
