The specific endpoint appears to serve Electronic Health Record (EHR) data, though the crawled documentation provides no details about the schema, fields, or data source behind this particular route. The platform advertises a uniform $0.02 per request pricing model with no API keys, no rate limits, and instant access.\n\nPayment is settled in USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) on Base. The x402 challenge confirms the endpoint is live, accepting POST requests with a max amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals). The payment recipient address is `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`, and the timeout is 300 seconds.\n\nThe platform lists many other endpoints across categories like AI/ML, finance, infrastructure, and data analytics, all at the same $0.02 price point. However, the `/api/v1/ehr/70` endpoint is not listed on the homepage catalog, and no documentation was found describing its request format, expected input body, or response schema. The \"EHR\" naming suggests electronic health records, but without documentation this is speculative. Prospective users should test the endpoint carefully and be aware that health data APIs may be subject to regulatory requirements (e.g., HIPAA).","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","pay-per-request","ehr-data","post-endpoint"],"categories":["health","data"],"synonyms":["electronic health records API","EHR API","health data endpoint","medical records API","x402 health API","lowpaymentfee EHR"],"warnings":["No documentation found for /api/v1/ehr/70 — request/response schema is completely unknown.","The endpoint is not listed on the provider's homepage API catalog, raising questions about its status.","EHR (Electronic Health Records) data may be subject to HIPAA or other health data regulations — compliance status is unknown.","All non-homepage crawled pages returned only 'Connect wallet' with no useful content, suggesting docs are behind a wallet gate or not yet built."],"endpointUrl":"https://lowpaymentfee.com/api/v1/ehr/70","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/70","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/request in USDC on Base).
