The specific resource `/api/v1/hipaa/records/41` 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; payment is handled inline through the x402 payment header.\n\nThe provider lowpaymentfee.com hosts a broad catalog of x402-enabled APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced uniformly at $0.02 per request. This particular endpoint falls under a healthcare/HIPAA category, though the crawled documentation is extremely sparse and provides no detail on the request schema, response format, or what \"records/41\" actually returns. The docs, pricing, and README pages all render only a \"Connect wallet\" prompt with no substantive content.\n\nBecause there is no OpenAPI spec, no request/response examples, and no documentation describing the data model or compliance posture, agents should treat this endpoint with caution. The HIPAA label in the URL path suggests health data, but there is no evidence of actual HIPAA compliance documentation, BAA availability, or audit certifications. The endpoint is confirmed live (402 challenge returned successfully).","tags":[],"capabilities":["x402-payment","per-request-billing","usdc-base","hipaa-records","http-post","no-api-key","no-rate-limit"],"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 OpenAPI or schema documentation available — request and response formats are unknown.","The URL path references 'HIPAA' but no compliance documentation, BAA, or audit evidence was found.
