x402-gated premium API access on Base, pay $0.02 per request in USDC — no keys required.
What it does
This endpoint at lowpaymentfee.com provides "Premium API Access" behind an x402 paywall on the Base network. The specific resource `/api/v1/claims/86` is one of many endpoints offered by the platform, which spans data & analytics, AI & machine learning, finance & Web3, and infrastructure utility categories. All endpoints on the platform are priced at $0.02 per request, payable in USDC (USD Coin) on Base, with no API keys, rate limits, or commitments required.
The x402 challenge confirms the endpoint is live and accepts POST requests. Payment is settled on-chain to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using the USDC contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` on Base. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02. The payment scheme is "exact" with a timeout of 300 seconds.
However, the specific functionality of `/api/v1/claims/86` is unclear. The platform's landing page lists various API categories but does not include a "claims" endpoint in its public catalog. No OpenAPI schema, detailed documentation, or example request/response payloads are available — the docs, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content. As a result, the actual input parameters and response format for this particular endpoint remain unknown.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no OpenAPI schema, no example requests or responses, and the specific purpose of /api/v1/claims/86 is not described anywhere in the crawled material. The docs/pricing/README pages are all empty beyond a wallet-connect prompt.
