Insurance claims data endpoint 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 54) 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 broader lowpaymentfee.com platform advertises a wide catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. However, the specific endpoint being listed here (/api/v1/insurance/claims/54) is not explicitly mentioned on the site's landing page catalog, which focuses on analytics, AI, finance, and utility endpoints. The insurance claims path may be part of an unlisted or newer vertical.
The endpoint is live and returned a proper 402 x402 challenge when probed. No OpenAPI schema, detailed documentation, or example responses were found in the crawl. The actual structure of the insurance claims response is unknown — the only confirmed output metadata is that it serves application/json. Without documentation on request body format or response fields, callers will need to experiment or contact the provider.

Quality

Warnings
- —No API documentation or OpenAPI schema available for this endpoint.
- —The /api/v1/insurance/claims/54 path is not listed on the provider's public catalog — its existence and data quality are unverified beyond the 402 challenge.
- —Response schema is completely unknown; callers must discover fields experimentally.
- —The endpoint references a single hardcoded claim ID (54); it is unclear whether other claim IDs are supported or how to query them.
