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 96) 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 (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 an insurance claims category, though the site's landing page does not list insurance endpoints among its featured API groups. No OpenAPI schema, detailed field documentation, or example responses are available for this endpoint, so the exact shape of the returned claims data is unknown.
The endpoint is confirmed live: the probe received a proper HTTP 402 challenge with x402 version 1, advertising the USDC asset contract (0x8335…2913) on Base. The payment timeout is 300 seconds. Because no request body schema or response schema is documented, callers will need to experiment or contact the provider to understand what fields to send and what data is returned.

Quality
The endpoint is confirmed live via a valid 402 challenge, but there is no OpenAPI schema, no documented request/response format, no example payloads, and the insurance claims category is not even listed on the provider's own landing page. Effectively a stub with verified liveness and pricing.
