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 #52) 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 provider, lowpaymentfee.com, hosts a broad catalog of pay-per-request APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per call with no API keys, no rate limits, and no commitments. The specific endpoint listed here falls under an insurance claims resource path, though no detailed documentation, request schema, or response schema is available beyond the x402 challenge metadata.
Because there is no OpenAPI spec, no example request/response payloads, and no dedicated documentation page for this endpoint, the actual fields accepted in the POST body and the structure of the returned claims data are unknown. The endpoint is confirmed live (returns a valid 402 challenge), but users should experiment or contact the provider to understand the expected input and output formats.

Quality
The endpoint is confirmed live via a valid x402 402 challenge, but there is no OpenAPI spec, no request/response schema, no dedicated documentation, and no example payloads. The insurance claims path is not mentioned anywhere on the provider's landing page, making the actual functionality unclear. Effectively a stub listing.

- —No example request or response payloads are available — input/output format is unknown
