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 56) via an x402 pay-per-request model. 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).
The provider, lowpaymentfee.com, hosts a broad catalog of x402-gated APIs spanning data & analytics, AI/ML inference, finance & Web3, and infrastructure utilities — all priced uniformly at $0.02 per call. No API keys or rate limits are advertised; access is granted immediately upon payment via the x402 protocol. The specific endpoint listed here falls under an insurance claims path, though the provider's landing page does not explicitly document this particular route or its response schema.
Because there is no OpenAPI spec, no documented request/response schema for this insurance claims endpoint, and no examples of what the returned data looks like, the practical utility is hard to assess without experimentation. The endpoint is confirmed live (returns a valid 402 challenge), but the lack of documentation means callers must discover the expected POST body and response format through trial and error.

Quality
The endpoint is confirmed live with a valid x402 402 challenge, but there is no OpenAPI spec, no request/response schema documentation, and the specific insurance claims path is not mentioned on the provider's landing page. Effectively a stub listing with confirmed liveness but minimal usable detail.
