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 70) 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 particular endpoint falls under what appears to be an insurance domain (`/api/v1/insurance/claims/70`), though the provider's landing page does not list insurance endpoints among its advertised categories. The endpoint accepts POST requests and returns JSON.
Because no OpenAPI schema, request body documentation, or sample responses are available for this specific endpoint, the exact input parameters and response structure are unknown. The endpoint is confirmed live (returns a well-formed 402 challenge), but callers will need to experiment or contact the provider to determine the expected POST body format.
