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 75) behind a per-request micropayment wall. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) via the x402 "exact" scheme. The maximum amount required per call is 20,000 base units of USDC, which equals $0.02 (USDC uses 6 decimals).
The broader lowpaymentfee.com platform advertises a catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities—all priced at $0.02 per request. The platform emphasizes no API keys, no rate limits, and instant access. However, the specific endpoint being listed here is an insurance claims resource (`/api/v1/insurance/claims/75`), which is not explicitly listed on the provider's landing page catalog. There is no OpenAPI schema, detailed documentation, or example request/response available for this endpoint, so the exact request body format and response structure are unknown.
The endpoint is confirmed live: it returns a proper HTTP 402 x402 challenge with version 1 headers. The payment recipient address is 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3, and the payment timeout is 300 seconds.
