x402-gated backup/data endpoint on Base, pay $0.02 per request in USDC with no API keys.
What it does
This endpoint at lowpaymentfee.com provides access to a backup resource (specifically the 2024-10 backup) via the x402 payment protocol. It is part of a broader platform offering multiple API categories including data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities—all gated behind per-request USDC micropayments on the Base network.
The specific endpoint `/api/v1/backups/2024-10` accepts POST requests and returns JSON. Payment is settled on-chain via USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base using the x402 "exact" scheme. The maximum amount required is 20,000 base units of USDC (6 decimals), which equals $0.02 per request. No API keys, rate limits, or subscriptions are needed—callers simply attach an X-PAYMENT header with a valid payment proof.
The platform advertises simple pay-per-use pricing across all its endpoints at $0.02/request. Documentation pages exist but appear to require wallet connection to view, so detailed request/response schemas are not publicly available. The endpoint is confirmed live via a proper 402 challenge response.
