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 3) 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, lowpaymentfee.com, hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services, all priced at $0.02 per request. This specific endpoint falls under an insurance claims category, though the site's landing page does not list it among the featured API groups. The endpoint accepts POST requests and returns application/json responses.
Because there is no OpenAPI schema, no documentation beyond the landing page, and no example request/response payloads available, the exact input parameters and response structure for this insurance claims endpoint are unknown. Callers should expect a JSON response but will need to experiment or contact the provider for details on required POST body fields.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no documentation for this specific insurance claims endpoint, no example request/response, and the endpoint is not even listed on the provider's landing page. Effectively a stub with confirmed liveness.
