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 22) via the x402 payment protocol. It is part of a broader platform offering dozens of pay-per-call API endpoints spanning data analytics, AI/ML inference, finance, crypto, infrastructure utilities, and more — all settled on the Base network using USDC.
The x402 challenge confirms the endpoint is live and accepts POST requests. The price for this specific endpoint is 20,000 base units of USDC (6 decimals), which equals $0.02 per request. The platform advertises uniform $0.02/request pricing across all its endpoints, with no API keys, no rate limits, and no minimum commitments required. Payment is made via the x402 "exact" scheme to a specified wallet address on Base.
Important caveats: the endpoint path suggests it returns data for a single insurance claim (ID 22), but no documentation, request/response schema, or example payloads are available. The platform's landing page lists this endpoint's category under broader offerings but provides no specifics about what fields the insurance claims response contains or what POST body parameters are accepted. Without an OpenAPI spec or detailed docs, the actual data returned and input format remain unknown.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI spec, no documentation of request/response schemas, no example payloads, and no explanation of what insurance claims data is actually returned. The endpoint path is very specific (claim 22) with no context on whether other claim IDs are available. Effectively a stub listing.
Warnings
- —No OpenAPI or schema documentation available for this endpoint
- —No example request or response payloads — input/output format is unknown
- —Endpoint path is hardcoded to claim ID 22; unclear if other claim IDs exist or are accessible
- —The broader platform lists many endpoint categories but provides no detailed docs for any of them
- —Insurance data may be subject to regulatory requirements (HIPAA, state insurance regulations) — no compliance information provided
