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 86) via a POST request, gated by the x402 payment protocol. Payment is settled in USDC on the Base network at $0.02 per request (20,000 base units of USDC with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The hosting site lowpaymentfee.com offers a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services, all uniformly priced at $0.02 per request. This particular endpoint falls under an insurance claims category, though the site's landing page does not list insurance endpoints among its featured API groups. The exact schema of the response payload is not documented; the x402 challenge confirms the output MIME type is application/json but provides no further field-level detail.
Because there is no OpenAPI spec, no example responses, and no documentation beyond the generic landing page, the actual data returned for claim 86 is unknown. Callers should treat this as a lightly documented endpoint and verify the response structure empirically before relying on it in production.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no example request/response, no documentation for the insurance claims resource, and the endpoint is not even listed on the provider's own landing page. Effectively a stub.
Warnings
- —No OpenAPI or schema documentation available for this endpoint
- —Insurance claims endpoint is not listed among the provider's advertised APIs on the landing page
- —Response payload structure is completely unknown — no field-level schema provided
- —Single hardcoded claim ID (86) — unclear if other claim IDs are accessible or what data is returned
