The specific `/ehr/86` path suggests an Electronic Health Record (EHR) resource, though the provider's landing page does not explicitly list or document EHR endpoints among its advertised categories. The endpoint is live and returns a valid x402 challenge.\n\nPayment is settled on the Base network using USDC (contract `0x8335…2913`) via the x402 \"exact\" scheme. The `maxAmountRequired` is 20,000 base units, which at 6 decimals equals $0.02 per request — consistent with the platform's uniform $0.02/request pricing. The endpoint accepts HTTP POST, requires no API keys or accounts, and advertises no rate limits. The x402 payment header is the sole authentication mechanism.\n\nDocumentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what data the `/ehr/86` resource actually returns. The \"86\" in the path may be a record identifier, but this is speculative. Users should be aware that this endpoint deals with a category label (\"EHR\") that typically involves sensitive health data, and no privacy or compliance information is provided by the platform.","tags":[],"capabilities":["x402-payment","pay-per-request","usdc-settlement","base-network","ehr-data","http-post","no-api-key"],"categories":["health","data"],"synonyms":["electronic health record","EHR API","health data endpoint","x402 EHR","pay-per-call health API","lowpaymentfee EHR","medical record API"],"warnings":["No documentation exists for the /api/v1/ehr/86 endpoint — it is not listed among the provider's advertised APIs","EHR (Electronic Health Record) data is typically subject to healthcare regulations (e.g., HIPAA); no compliance or privacy information is provided","All crawled subpages (docs, API, pricing, README) returned only 'Connect wallet' with no content","No request or response schema available — the data format is entirely unknown","The '86' in the path may be a specific record ID; it is unclear whether other IDs are valid or what data is returned"],"endpointUrl":"https://lowpaymentfee.com/api/v1/ehr/86","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/ehr/86","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live and returns a valid x402 challenge with clear pricing, but there is zero documentation on what the EHR endpoint actually returns, no request/response schema, and the crawled pages are empty beyond a wallet prompt.
