Insurance claims data endpoint on Base, pay-per-request via x402 with USDC.
What it does
This x402-enabled endpoint at `/api/v1/insurance/claims/90` is part of the lowpaymentfee.com platform, which hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML, finance, infrastructure utilities, and more. Each request is paid individually using USDC on the Base network via the x402 protocol — no API keys, no subscriptions, no rate limits.
The specific endpoint probed serves insurance claims data (resource ID 90). The x402 challenge indicates a maximum cost of 20,000 base units of USDC (0.02 USD per request), consistent with the site-wide $0.02/request pricing. Payment is settled on-chain to a designated address using the exact-amount scheme. The endpoint accepts HTTP POST requests and returns `application/json` responses.
While the platform advertises a wide range of endpoints, documentation is minimal — there is no OpenAPI spec, no request/response schema beyond the x402 challenge metadata, and the crawled pages beyond the homepage returned only wallet-connect prompts. The actual structure of the insurance claims data returned is unknown, so callers should expect to discover the response format empirically.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema documentation, no examples, and the crawled docs pages are empty. The purpose of the insurance claims endpoint is only inferable from the URL path. This is effectively a stub listing.
Warnings
- —No OpenAPI or schema documentation available — request and response formats are unknown.
- —The insurance claims endpoint is not listed on the provider's homepage catalog, raising questions about its status or discoverability.
- —Crawled /api, /pricing, and /README pages returned only 'Connect wallet' with no useful content.
