HIPAA health records endpoint paid per-request via x402 on Base (USDC).
What it does
This endpoint at lowpaymentfee.com provides access to HIPAA-related health records via a pay-per-call x402 protocol. The specific resource `/api/v1/hipaa/records/44` is accessed via HTTP POST and costs $0.02 per request, settled in USDC on the Base network. No API keys, rate limits, or subscriptions are required — callers simply attach an x402 payment header with each request.
The endpoint is part of a broader platform (lowpaymentfee.com) that hosts dozens of paid API endpoints across categories including data analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced uniformly at $0.02 per call. The x402 challenge confirms the endpoint is live, accepting the "exact" payment scheme with a max amount of 20,000 base units of USDC (6 decimals → $0.02). Payment is directed to wallet `0x1A2B...85F3` on Base, with a 300-second timeout.
Important caveat: the endpoint is labeled "HIPAA records," which implies it deals with protected health information. However, there is no documentation available describing the request format, response schema, authentication beyond payment, or what data is actually returned. The docs, pricing, and README pages on the site all render only a "Connect wallet" prompt with no substantive content. Without documentation, it is impossible to verify what this endpoint actually does, whether it truly handles PHI, or what compliance measures (if any) are in place.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02/request in USDC on Base). However, there is zero documentation on request/response schemas, no OpenAPI spec, no examples, and the docs pages are empty. The HIPAA label raises serious compliance concerns with no supporting information.
Warnings
- —Endpoint claims to serve HIPAA records but no compliance documentation, BAA, or privacy policy is available
- —No request or response schema documentation exists — behavior is entirely unknown
- —All documentation pages (docs, pricing, README) render only 'Connect wallet' with no content
- —Regulated health data category — use with extreme caution
- —The specific record ID (44) is hardcoded in the URL; unclear if other IDs are available or what they represent
