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 85) via an x402 pay-per-request model. Payment is settled in USDC on the Base network. The x402 challenge indicates a maximum cost of $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 provider site (lowpaymentfee.com) hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services, all priced uniformly at $0.02 per request. This specific endpoint falls under what appears to be an insurance claims category, though the site's landing page does not explicitly list insurance endpoints among its featured categories. The endpoint accepts POST requests and returns application/json.
Because no OpenAPI schema, request body documentation, or sample responses are available for this endpoint, the exact input parameters and response structure are unknown. The endpoint is confirmed live (returns a well-formed 402 challenge), but consumers should expect to experiment with request payloads or contact the provider for documentation.

Quality
The endpoint is confirmed live with a valid x402 402 challenge, but there is no OpenAPI schema, no request/response documentation, and no examples. The insurance claims category is not listed on the provider's landing page, making the endpoint's actual data content uncertain. This is effectively a stub listing.
Warnings
- —No API documentation, OpenAPI spec, or example responses available for this endpoint.
- —The insurance claims endpoint is not listed among the provider's advertised API categories, raising questions about its completeness or intended audience.
- —Request body schema is entirely unknown — callers must guess or discover parameters experimentally.
- —The endpoint path includes a hardcoded claim ID (85); it is unclear whether other claim IDs are available or how to query them.
