The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of $0.02 per request (20,000 base units at 6 decimals). No API keys or rate limits are advertised; callers pay per request by attaching an X-PAYMENT header.\n\nThe broader lowpaymentfee.com platform advertises a wide catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities—all priced at $0.02 per request on the Base network. However, the specific endpoint listed here is under the path `/api/v1/hipaa/records/94`, which is not featured on the site's public landing page. No documentation, request schema, or response schema is provided for this particular endpoint beyond the x402 challenge metadata. The HIPAA label suggests it may return protected health information, but no details on data format, required POST body, or compliance guarantees are available from the crawled material.\n\nBecause the endpoint is live (returns a valid 402 challenge) but lacks any documentation, example payloads, or explanation of what the returned record contains, consumers should treat this as an opaque, undocumented endpoint. The HIPAA label raises regulatory concerns that are not addressed in any visible documentation.","tags":[],"capabilities":["x402-payment","per-request-billing","usdc-base-network","hipaa-records","json-response","no-api-key"],"categories":["health","data"],"synonyms":["HIPAA API","health records API","medical records endpoint","x402 health data","pay-per-call HIPAA","Base USDC API","lowpaymentfee HIPAA"],"warnings":["No documentation or schema available for this specific endpoint","HIPAA-labeled endpoint with no visible compliance, privacy policy, or BAA documentation","Endpoint path /api/v1/hipaa/records/94 is not listed on the provider's public landing page","No request body schema or response schema provided—callers cannot know what to send or expect","Regulated health data category: verify legal and compliance requirements before use"],"endpointUrl":"https://lowpaymentfee.com/api/v1/hipaa/records/94","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/94","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/response schemas, no examples, and the HIPAA label raises serious regulatory questions with no visible compliance information.
