Insurance claims data endpoint on Base, pay-per-request via x402 with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to insurance claims data (specifically claim ID 79) via the x402 payment protocol. It accepts POST requests and returns JSON. 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 endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities, all priced at $0.02 per request. However, the specific endpoint listed here — `/api/v1/insurance/claims/79` — is not documented on the provider's landing page among the advertised API categories. It is live and returns a proper 402 challenge, but its exact response schema and the nature of the insurance claims data it returns are undocumented.
Because there is no OpenAPI spec, no example responses, and no documentation specific to this insurance claims endpoint, the actual data returned is unknown. Callers should be aware that this endpoint may return mock or placeholder data, as the provider's site appears to be a demonstration of low-fee x402 micropayments rather than a specialized insurance data service.
