x402-gated medical records endpoint on Base, pay-per-request with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to a medical records resource (`/api/v1/medical/records/1`) behind an x402 payment wall. The endpoint is live and returns a 402 challenge requesting payment in USDC on the Base network. The maximum amount required per request is 20,000 base units of USDC (6 decimals), which equals $0.02 USD. Payment is made via the x402 "exact" scheme to the specified wallet address.
The provider's landing page advertises a broad catalog of pay-per-call 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 under a `/medical/records/` path. No documentation, request schema, or response schema is provided for this particular endpoint beyond the generic "Premium API Access" description. The actual data returned, required POST body format, and the nature of the medical records are entirely unknown from the available material.
Because this endpoint deals with a path labeled "medical/records," it potentially involves health-related data, which may be subject to regulatory requirements (e.g., HIPAA in the US). No information about data provenance, compliance, or the nature of the records is available.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base). However, there is no documentation, no request/response schema, no examples, and the nature of the 'medical records' data is completely unknown. The listing is effectively a stub with a regulatory concern.
Warnings
- —No request or response schema available — the POST body format and returned data structure are unknown.
- —Endpoint path suggests medical/health data; no information on regulatory compliance (HIPAA, etc.) is provided.
- —No OpenAPI spec, no README content, and no detailed docs were found during crawl.
- —The actual content and provenance of the 'medical records' data is entirely unclear.
