The specific resource `/api/v1/hipaa/records/33` accepts POST requests and charges up to $0.02 per call in USDC on the Base network. Payment is handled entirely through the x402 header mechanism — no API keys, accounts, or rate limits are required.\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 uniformly at $0.02 per request. However, the specific HIPAA records endpoint is notable because it sits in a healthcare/compliance category. The crawled documentation pages (docs, pricing, README) returned only a wallet-connect prompt with no substantive content, so the exact schema of request inputs and response payloads for this endpoint is unknown.\n\nBecause the endpoint's name references HIPAA — a U.S. healthcare data privacy regulation — users should exercise caution. There is no documentation confirming what data is returned, whether the service is actually HIPAA-compliant, or what record ID 33 represents. The x402 challenge is live and well-formed, confirming the endpoint is operational, but the lack of documentation and the sensitive category warrant careful evaluation before use.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","hipaa-records","post-endpoint","no-api-key"],"categories":["healthcare","data"],"synonyms":["HIPAA API","health records API","medical records endpoint","x402 healthcare","pay-per-call HIPAA","lowpaymentfee HIPAA"],"warnings":["Endpoint references HIPAA (healthcare privacy regulation) but no compliance documentation or certifications are provided.","No request or response schema is documented — input format and output structure are entirely unknown.","All documentation pages (docs, pricing, README) returned only a wallet-connect prompt with no content.","Record ID 33 is hardcoded in the URL; it is unclear what this identifier represents or whether other IDs are valid.","The platform appears to be a generic x402 demo site; the actual data served by this endpoint is unverified."],"endpointUrl":"https://lowpaymentfee.com/api/v1/hipaa/records/33","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/33","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The x402 challenge is live and well-formed, confirming the endpoint works.
