x402-gated backup endpoint on Base, paying $0.02 in USDC per request.
What it does
This endpoint at lowpaymentfee.com provides access to a backup resource at the path `/api/v1/backups/2026-01`. It is part of a broader platform that offers a variety of x402-protocol pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per call, settled in USDC on the Base network.
The specific `/api/v1/backups/2026-01` endpoint accepts POST requests and returns `application/json` responses. Payment is handled via the x402 protocol: callers must include an `X-PAYMENT` header with a valid payment proof. The maximum amount required is 20,000 base units of USDC (6 decimals), which equals $0.02. The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base, with a timeout of 300 seconds.
The platform advertises no API keys, no rate limits, and instant access. However, documentation beyond the landing page is essentially empty (all doc/pricing/API pages just show "Connect wallet"), so the exact request body schema and response format for this backup endpoint are unknown. The endpoint is confirmed live via a valid 402 challenge.
