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 9) via the x402 payment protocol. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of $0.02 per request (20,000 base units at 6 decimals).
The hosting site lowpaymentfee.com offers a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. This particular endpoint falls under an insurance claims category that is not prominently listed on the site's landing page, so the exact response schema and data contents are unclear.
Because there is no OpenAPI specification, no documentation beyond the landing page, and no example responses available, the precise fields returned for an insurance claim lookup are unknown. The endpoint is confirmed live (returning a valid 402 x402 challenge), but prospective consumers should be aware that the data contract is undocumented.

Quality
The endpoint is confirmed live with a valid x402 402 challenge, but there is no OpenAPI spec, no documentation of request/response schemas, and the insurance claims category isn't even listed on the site's landing page. The data returned is entirely unknown, making this effectively a stub listing.
Warnings

- —Response format and fields are completely undocumented
