HIPAA health records endpoint, pay-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/91` is described as "Premium API Access" and accepts POST requests. Payment is settled in USDC on the Base network at $0.02 per request (20,000 base units of USDC with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The provider, lowpaymentfee.com, hosts a broad catalog of pay-per-request APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services, all priced uniformly at $0.02 per call. However, the specific HIPAA records endpoint is not listed on the provider's public landing page among the advertised API categories, which raises questions about its documentation status and intended use.
No OpenAPI schema, request/response examples, or detailed documentation were found for this endpoint. The crawled docs, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content. The endpoint is confirmed live — it returns a proper 402 challenge with x402 version 1. Given the HIPAA label, this endpoint likely deals with protected health information, which carries significant regulatory implications.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no documentation, no request/response schema, no examples, and the HIPAA records endpoint is not listed on the provider's own landing page. The HIPAA label implies regulated health data but no compliance documentation is available.
