The specific resource `/api/v1/hipaa/records/46` is described as \"Premium API Access\" and accepts POST requests. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum charge of $0.02 per request (20,000 base units at 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 broader lowpaymentfee.com platform advertises a wide catalog of x402-gated endpoints spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance/crypto market data, and infrastructure utilities, all uniformly priced at $0.02 per request. However, the specific endpoint listed here falls under a \"HIPAA records\" path, which is not documented on the site's landing page or any crawled documentation. No schema for request body or response body is provided, and the docs, pricing, and README pages all returned only a \"Connect wallet\" prompt with no additional content.\n\nBecause the endpoint path references HIPAA-regulated health data but no documentation explains what data is returned, what input is expected, or what compliance measures are in place, callers should exercise caution. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the lack of documentation about the actual data served makes it difficult to assess fitness for any particular use case.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","hipaa-records","post-endpoint","no-api-key"],"categories":["health","data"],"synonyms":["HIPAA API","health records API","medical records endpoint","x402 health data","pay-per-call HIPAA","lowpaymentfee HIPAA"],"warnings":["Endpoint path references HIPAA-regulated health data but no compliance documentation or privacy policy is available","No request body schema or response schema documented anywhere","The /api/v1/hipaa/records/46 path is not listed on the provider's landing page among their advertised APIs","Docs, pricing, and README pages returned no meaningful content","Handling of protected health information (PHI) without documented safeguards poses regulatory risk"],"endpointUrl":"https://lowpaymentfee.com/api/v1/hipaa/records/46","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/46","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 no documentation for request/response schemas, no OpenAPI spec, and the HIPAA records path is not mentioned anywhere in the site's crawled content.
