Insurance claims data endpoint on Base, pay-per-request via x402 with USDC.
What it does
This x402-enabled endpoint at lowpaymentfee.com serves insurance claims data (specifically claim ID 63) behind a per-request USDC micropayment on the Base network. The endpoint accepts POST requests and returns JSON. Payment is settled on-chain using USDC (contract 0x8335…2913 on Base) at $0.02 per request.
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 listed here falls under an insurance claims path (`/api/v1/insurance/claims/63`), though the site's landing page does not explicitly document this particular route or its response schema. There is no OpenAPI spec, no detailed documentation, and no example request/response available from the crawl.
Because the endpoint returned a valid 402 challenge with a well-formed x402 payment envelope, it is confirmed live. However, the lack of any documented input/output schema for this specific insurance claims endpoint, and its absence from the provider's own listed API catalog, means agents must discover its behavior empirically. The maxAmountRequired of 20000 base units (USDC has 6 decimals) translates to $0.02 USD per call, consistent with the site's uniform pricing.

Quality
The endpoint is confirmed live via a valid 402 challenge and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no documented input/output schema, no example responses, and this specific insurance claims path is not listed on the provider's own catalog page. Effectively a stub with confirmed liveness.
Warnings
- —This specific endpoint (/api/v1/insurance/claims/63) is not listed on the provider's own API catalog page — its purpose and response format are undocumented.
- —No OpenAPI specification or schema documentation is available.
- —No example request or response bodies could be obtained from the crawl.
- —The hardcoded claim ID '63' in the path suggests this may be a single-resource endpoint rather than a general claims query API.
