Pay-per-call insurance claims API on Base, settled in USDC via x402.
What it does
This endpoint at lowpaymentfee.com provides access to an insurance claims resource (claim ID 49) via the x402 payment protocol. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request (20,000 base units with 6 decimals).
The endpoint is part of a broader platform (lowpaymentfee.com) that offers a variety of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. The specific endpoint `/api/v1/insurance/claims/49` is not listed on the site's main catalog, but it follows the same x402 payment pattern and pricing as the other endpoints.
Because no OpenAPI schema, request/response examples, or detailed documentation are available for this specific endpoint, the actual data returned for insurance claim 49 is unknown. The endpoint is confirmed live (returns a valid x402 402 challenge), but the lack of documentation means callers must discover the response format empirically.
