Pay-per-call medical records endpoint on Base via x402, settled in USDC at $0.02/request.
What it does
This endpoint at `/api/v1/medical/records/59` is part of the lowpaymentfee.com platform, which offers a broad catalog of pay-per-request APIs spanning data analytics, AI/ML inference, finance, and infrastructure utilities. All endpoints use the x402 payment protocol, settling in USDC on the Base network. The specific resource at `/medical/records/59` is listed under the provider's generic "Premium API Access" label; no further documentation describes the schema or semantics of the medical records data returned.
The x402 challenge confirms the endpoint is live and accepts POST requests. The `maxAmountRequired` is 20,000 base units of USDC (6 decimals), which equals $0.02 per request — consistent with the site-wide flat pricing advertised on the landing page. Payment is sent to `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` with a 300-second timeout. No API keys or rate limits are required; access is gated entirely by the x402 micropayment.
Important caveats: there is no OpenAPI schema, no request/response documentation, and no explanation of what "medical records" data is actually served. The endpoint path suggests health-related data, which may carry regulatory implications (HIPAA, GDPR). Prospective consumers should verify data provenance and compliance before integrating.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is zero documentation on request parameters, response schema, or what medical records data is actually returned. No OpenAPI spec, no examples, and the health-data category raises regulatory concerns with no compliance information provided.
Warnings
- —No request or response schema documentation available
- —Endpoint serves 'medical records' data with no stated compliance (HIPAA, GDPR, etc.) — verify data provenance before use
- —The provider site offers many endpoint categories but individual endpoint docs are absent
- —The specific record ID '59' in the path is unexplained — unclear if this is a fixed demo or parameterized resource
