Pay-per-call medical records endpoint on Base via x402, settled in USDC at $0.02/request.
What it does
This x402-enabled endpoint at `/api/v1/medical/records/85` is part of a broader suite of pay-per-request APIs hosted on lowpaymentfee.com. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) with a maximum amount of 20,000 base units, which equals $0.02 (USDC uses 6 decimals). The x402 challenge was successfully captured, confirming the endpoint is live.
The provider offers a wide catalog of APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced uniformly at $0.02 per request. The specific endpoint in this listing appears to serve medical records data (resource path `/api/v1/medical/records/85`), though the provider's landing page does not list a dedicated "medical" category, and no documentation, schema, or example payloads are available for this particular route. The endpoint's description is simply "Premium API Access," which is generic and uninformative about the actual data returned.
Because no OpenAPI spec, request/response schema, or detailed documentation exists for this endpoint, the exact input parameters and output format are unknown. The provider advertises no API keys, no rate limits, and instant access. Agents should send a POST request with an `X-PAYMENT` header containing a valid x402 payment proof to receive the response.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation for this specific medical records route, and the endpoint path is not listed on the provider's own landing page. The "medical records" label raises regulatory concerns with zero supporting detail.
