x402-gated insurance claims API on Base, pay $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to an insurance claims resource via the x402 payment protocol. The specific endpoint `/api/v1/insurance/claims/1` returns insurance claim data (presumably for claim ID 1) in JSON format, gated behind a per-request USDC micropayment on the Base network. The x402 challenge confirms the endpoint is live and accepts exact-scheme payments.
The provider operates a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments required. Payment is settled in USDC (contract 0x8335…2913) on Base L2. The x402 challenge for this specific endpoint advertises a maxAmountRequired of 20000 base units, which equals $0.02 (USDC uses 6 decimals).
Note that the actual data returned by this insurance claims endpoint is not documented. There is no OpenAPI schema, no request/response examples, and no dedicated documentation page for this resource. The provider's site pages beyond the landing page return only a "Connect wallet" prompt with no further content. Treat this as a functional but minimally documented endpoint.
