Insurance claims data endpoint on Base, pay-per-request via x402 with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to insurance claims data (specifically claim #37) via the x402 payment protocol. It is part of a broader platform offering dozens of pay-per-call API endpoints spanning data analytics, AI/ML inference, finance, crypto, infrastructure utilities, and more — all settled on the Base network using USDC.
The x402 challenge confirms the endpoint is live and accepts POST requests. Payment is settled on-chain on Base using USDC (contract 0x8335…2913) with an exact-payment scheme. The maximum amount required is 20,000 base units of USDC, which equals $0.02 per request (USDC uses 6 decimals). The platform advertises no API keys, no rate limits, and instant access — you simply attach an X-PAYMENT header with a valid x402 payment proof.
Notably, the specific endpoint path `/api/v1/insurance/claims/37` is not listed on the provider's landing page among the advertised API categories (Data & Analytics, AI & ML, Finance & Web3, Infrastructure). It may be an unlisted or supplementary endpoint. No OpenAPI schema, request/response examples, or detailed documentation were found for this particular resource, so the exact shape of the insurance claims data returned is unknown.

Quality
The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI schema, no request/response examples, no documentation for this specific insurance claims path, and the endpoint is not even listed on the provider's own landing page. The actual data returned is entirely unknown.
Warnings
- —Endpoint path /api/v1/insurance/claims/37 is not listed among the provider's advertised APIs — may be unlisted or experimental.
- —No request body schema or response schema available; the shape of returned insurance claims data is unknown.
- —No OpenAPI spec, README, or detailed docs were accessible (pages returned only 'Connect wallet').
- —Single hardcoded claim ID (37) in the path — unclear if other claim IDs are supported or how discovery works.
