Database snapshot access (2024-11) via x402 micropayment on Base network for $0.02 per request.
What it does
This endpoint provides access to a database snapshot dated November 2024, served by lowpaymentfee.com. It uses the x402 payment protocol, requiring a per-request micropayment of $0.02 in USDC on the Base network. The endpoint accepts POST requests and returns JSON data.
The provider lowpaymentfee.com hosts a variety of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no commitments required. This specific endpoint (`/api/v1/database/snapshots/2024-11`) appears to deliver a historical database snapshot, though the exact schema of the returned data is not documented in the available crawl material.
Payment is settled on-chain via USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on the Base L2 network. The x402 challenge specifies a maximum amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals) with a timeout of 300 seconds. No OpenAPI spec or detailed response schema was found.
