Insurance claims data endpoint on Base, paid per-request via x402 with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to insurance claims data (specifically claim ID 14) via the x402 payment protocol. It accepts POST requests and returns JSON. Payment is settled in USDC on the Base network at $0.02 per request (maxAmountRequired of 20,000 base units with 6 decimals = $0.02). No API keys or rate limits are required; access is granted instantly upon payment.
The hosting site lowpaymentfee.com offers a broad catalog of x402-gated API endpoints spanning data & analytics, AI/ML inference, finance & Web3, and infrastructure utilities — all priced at $0.02 per request. This particular endpoint falls under an insurance claims category, though the site's landing page does not explicitly list it among the featured APIs. The exact schema of the returned claims data is not documented, so callers should expect a JSON response but cannot confirm the field structure without making a paid request.
Because there is no OpenAPI spec, no request/response schema documentation, and no example payloads available, the endpoint's precise input parameters and output fields remain unknown. The x402 challenge is live and well-formed, confirming the endpoint is operational and accepting payments to wallet 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 via USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base.

Quality
The x402 challenge is live and well-formed, confirming the endpoint is operational. However, there is no OpenAPI spec, no request/response schema, no example payloads, and the insurance claims endpoint is not even listed on the provider's landing page. Effectively a stub with confirmed liveness.
