Insurance claims data endpoint on Base, pay-per-request via x402 with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to insurance claims data (specifically claim ID 81) 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 USDC's 6 decimals = $0.02). 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 on the Base network. This particular endpoint falls under an insurance claims category, though the site's landing page does not list insurance endpoints among its featured categories. No OpenAPI schema, detailed documentation, or example responses are available for this specific endpoint, so the exact shape of the returned claims data is unknown.
The endpoint is live and returns a proper x402 402 challenge when called without payment. The x402 version is 1, the payment scheme is "exact," and the timeout is 300 seconds. The USDC asset contract on Base is 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no OpenAPI schema, no documentation for the insurance claims endpoint specifically, no example request/response payloads, and the insurance category is not even listed on the provider's landing page. The listing is essentially a stub with confirmed liveness and pricing.
