Insurance claims lookup API on Base, paid per-request via x402 in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to insurance claims data (specifically claim ID 100 in this URL pattern) 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 $0.02 per request (20,000 base units at 6 decimals).
The provider, lowpaymentfee.com, hosts a broad catalog 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 minimum commitments. The specific endpoint probed here falls under an insurance claims path (`/api/v1/insurance/claims/100`), though this particular route is not listed on the provider's public landing page among the advertised API categories. The x402 challenge was successfully captured, confirming the endpoint is live.
Because there is no OpenAPI schema, no request/response examples, and no documentation beyond the generic landing page, the actual data returned by this endpoint is unknown. It is unclear whether the path parameter `100` represents a specific claim ID, a pagination offset, or something else. Callers should be prepared to experiment or contact the provider for documentation.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no request/response examples, no documentation for this specific insurance claims path, and the endpoint isn't even listed on the provider's own landing page. Effectively a stub listing.
