Pay-per-call insurance claims API on Base via x402, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to an insurance claims resource (claim ID 66) 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 20,000 base units, which equals $0.02 per request (USDC uses 6 decimals).
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 minimum commitments. This specific endpoint falls under an insurance claims category, though the exact data returned (claim details, status, adjudication info, etc.) is not documented beyond the generic "Premium API Access" label.
Because there is no OpenAPI schema, no request/response examples, and no documentation beyond the landing page listing, the precise input parameters and output structure are unknown. Agents should expect a JSON response but will need to experiment or contact the provider for field-level details.
