The specific `/ehr/26` path suggests an Electronic Health Record (EHR) resource, though the provider's landing page does not explicitly list or document this particular endpoint. The platform advertises $0.02 per request across all endpoints, and the x402 challenge confirms a maxAmountRequired of 20,000 base units of USDC (6 decimals) on Base network, which equals $0.02.\n\nPayment is handled via the x402 exact-payment scheme: callers send a signed USDC payment in the `X-PAYMENT` header and receive the JSON response directly — no API keys, accounts, or rate limits. The endpoint accepts POST requests and returns `application/json`. The pay-to address is `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base mainnet, settling in USDC (`0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`).\n\nDocumentation is extremely sparse. The crawled docs, pricing, and API pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what data the `/ehr/26` endpoint actually returns or what input it expects. The EHR designation raises potential concerns about health data regulation (HIPAA, etc.), but no compliance information is provided.","tags":[],"capabilities":["x402-payment","pay-per-request","usdc-settlement","base-network","ehr-data","json-response","no-api-key"],"categories":["health","data"],"synonyms":["electronic health record API","EHR endpoint","health data API","x402 health API","pay-per-call EHR","lowpaymentfee EHR","USDC health data"],"warnings":["The /api/v1/ehr/26 path is not listed among the provider's advertised endpoints on the landing page — its purpose and data content are unknown.","No request body schema or response schema is documented anywhere; callers must guess at the expected input.","EHR (Electronic Health Record) data may be subject to HIPAA or other health data regulations — no compliance information is provided.","All documentation pages (docs, pricing, API, README) render only a 'Connect wallet' prompt with no substantive content.","No OpenAPI spec or ai-plugin manifest is available."],"endpointUrl":"https://lowpaymentfee.com/api/v1/ehr/26","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/26","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base).
