x402-gated medical records endpoint on Base, paid per-request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to a medical records resource (`/api/v1/medical/records/10`) behind an x402 paywall. The endpoint is live and returns a standard x402 challenge when called without payment. Payment is settled on the Base network using USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) with an exact-scheme payment of up to 20,000 base units, which equals $0.02 (USDC uses 6 decimals). The endpoint accepts POST requests and returns `application/json`.
The broader lowpaymentfee.com platform advertises a wide catalog of x402-gated APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. However, the specific endpoint being listed here is in the "medical/records" path, which is not explicitly listed on the provider's landing page catalog. No documentation, request schema, or response schema is available for this particular endpoint, so the actual data returned and required input fields are unknown.
Because this endpoint deals with medical records, it may involve sensitive health data. There is no visible documentation about data sourcing, compliance (e.g., HIPAA), or what the returned records actually contain. Callers should exercise caution and verify the nature of the data before relying on it for any health-related application.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no documentation, no request/response schema, and the specific medical records path is not listed in the provider's own catalog. The nature and source of the medical data are entirely unknown, and the health data category raises compliance concerns.
Warnings
- —No documentation or schema available for this endpoint — input/output format is unknown.
- —Endpoint path '/api/v1/medical/records/10' is not listed on the provider's landing page catalog, raising questions about its provenance.
- —Medical/health data category: no information about HIPAA compliance, data sourcing, or privacy protections is provided.
- —The hardcoded record ID '10' in the URL suggests this may be a demo or placeholder resource rather than a general-purpose API.
