Insurance claims data endpoint on Base, pay-per-request via x402 with USDC.
What it does
This x402-enabled endpoint at lowpaymentfee.com provides access to insurance claims data (specifically claim ID 97) via a POST request. Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request. The endpoint requires no API keys, no rate limits, and offers instant access — you 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 & Web3, infrastructure utilities, and more — all priced at $0.02 per request. This particular endpoint falls under an insurance claims category, though the provider's landing page does not list it among its featured API groups. No OpenAPI schema, request/response examples, or detailed documentation were found for this specific endpoint, so the exact input fields and response structure are unknown.
The endpoint is confirmed live: it returns a proper HTTP 402 x402 challenge when called without payment. The x402 challenge specifies scheme "exact", network "base", asset contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 (USDC on Base), and a max amount of 20000 base units (i.e., $0.02 given USDC's 6 decimals). The payment recipient address is 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a timeout of 300 seconds.
