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 23) via an x402 pay-per-request model. The endpoint accepts POST requests and returns JSON. Payment is settled in USDC on the Base network.
The x402 challenge advertises a maxAmountRequired of 20000 base units of USDC (6 decimals), which equals $0.02 per request. The provider's landing page confirms a flat $0.02/request pricing across all their API endpoints, with no API keys, no rate limits, and instant access. The provider hosts a broad catalog of endpoints spanning data analytics, AI/ML inference, finance, crypto, infrastructure utilities, and — as in this case — insurance claims.
Documentation is extremely sparse. There is no OpenAPI spec, no request/response schema, and no description of what fields the insurance claims endpoint actually returns or what POST body it expects. The landing page lists this endpoint's category implicitly but provides no further detail on the insurance domain. Prospective callers should expect to experiment with the endpoint to discover its input/output contract.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02/request in USDC on Base), but there is no OpenAPI spec, no request/response schema, no documentation on what the insurance claims endpoint accepts or returns, and the crawled pages beyond the landing page are empty. This is effectively a stub listing.
Warnings
- —No OpenAPI or schema documentation available — request and response formats are unknown
- —Insurance claims data may be subject to regulatory requirements (HIPAA, state insurance regulations) depending on jurisdiction and data contents
- —The endpoint path references a specific claim ID (23); it is unclear whether other IDs are supported or what the full resource model looks like
- —No examples or descriptions of the insurance domain are provided by the source
