Insurance claims data endpoint on Base, paid per-request via x402 in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to insurance claims data (specifically claim ID 48) via an x402 pay-per-call model. Payment is settled in USDC on the Base network. The x402 challenge indicates a maximum cost of $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 site (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. This specific endpoint falls under what appears to be an insurance domain, though the site's landing page does not list insurance endpoints among its featured categories. No OpenAPI schema, request/response examples, or detailed documentation were found for this endpoint, so the exact request body format and response structure are unknown.
The endpoint is live and returns a well-formed x402 challenge (HTTP 402) when called without payment. It accepts POST requests and returns application/json. The payment is routed to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no OpenAPI schema, no documented request/response format, and the insurance claims category is not listed on the provider's own landing page. Effectively a stub with confirmed liveness.
