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 72) via an x402 pay-per-request 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, lowpaymentfee.com, hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services, all priced uniformly at $0.02 per request. This specific endpoint falls under an insurance claims category, though the provider's landing page does not list insurance endpoints among its featured API groups. The endpoint accepts POST requests and returns application/json.
Because no OpenAPI schema, request body schema, or example responses are available, the exact fields accepted or returned by this endpoint are unknown. The endpoint is confirmed live (402 challenge captured), but documentation is effectively absent beyond the x402 challenge metadata.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no request/response examples, no documentation for the insurance claims resource, and the provider's own landing page does not even list this endpoint category. Effectively a stub listing.
