The specific resource `/api/v1/hipaa/records/5` is accessed via HTTP POST and costs $0.02 per request, settled in USDC on the Base network. No API keys or rate limits are required; callers simply attach an x402 payment header to each request.\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 at a uniform $0.02/request price point. However, this specific listing covers the HIPAA records endpoint. The x402 challenge confirms the endpoint is live, accepting payments to address `0x1A2B...85F3` using USDC (`0x8335...2913`) on Base.\n\nImportant caveats: the crawled documentation pages (docs, pricing, README) all returned only a \"Connect wallet\" stub with no substantive content. There is no OpenAPI schema, no request/response examples, and no documentation describing what data the HIPAA records endpoint actually returns, what input it expects in the POST body, or what \"records/5\" refers to. The endpoint's name references HIPAA (health data privacy regulation), which implies it may handle protected health information — a regulated category that warrants caution.","tags":[],"capabilities":["x402-payment","per-request-billing","usdc-settlement","base-network","hipaa-records","health-data","no-api-key","post-endpoint"],"categories":["health","data"],"synonyms":["HIPAA API","health records API","medical records endpoint","x402 health data","pay-per-call HIPAA","lowpaymentfee HIPAA","Base USDC health API"],"warnings":["No API documentation available — all doc pages return only 'Connect wallet' stubs","No request or response schema provided; unknown what POST body is expected","Endpoint references HIPAA (regulated health data) but no compliance documentation, BAA, or privacy policy is available","The specific meaning of 'records/5' is undocumented — unclear if this is a fixed resource or parameterized path","No OpenAPI spec or examples exist to verify actual functionality"],"endpointUrl":"https://lowpaymentfee.com/api/v1/hipaa/records/5","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/5","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 confirms pricing and payment details, but there is zero documentation on request format, response schema, or what the endpoint actually returns.
