Insurance claims data endpoint on Base, pay-per-request via x402 with USDC.
What it does
This x402-enabled endpoint at lowpaymentfee.com serves insurance claims data (specifically claim ID 57) behind a per-request USDC micropayment on the Base network. The endpoint accepts POST requests and returns JSON. Payment is settled on-chain using USDC (contract 0x8335…2913 on Base) at $0.02 per request.
The provider, lowpaymentfee.com, hosts 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 landing page, so its exact response schema and the nature of the claims data it returns are unclear.
The endpoint is live: the probe received a proper HTTP 402 x402 challenge with version 1, confirming it is operational and ready to accept payments. The x402 challenge specifies a maxAmountRequired of 20000 base units of USDC (6 decimals), which equals $0.02. No OpenAPI schema, detailed documentation, or example responses were found in the crawl.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no OpenAPI schema, no documentation for the insurance claims resource, no example request/response, and the endpoint path is not listed on the provider's landing page. Effectively a stub listing with confirmed liveness.
Warnings
