Pay-per-call premium API access on Base network via x402 protocol at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides "Premium API Access" via the x402 payment protocol. The specific path `/api/v1/trades/130` suggests a trades-related data endpoint, though the site broadly offers APIs across data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities—all priced at $0.02 per request.
Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The x402 challenge indicates a maxAmountRequired of 20000 base units, which equals $0.02 (USDC uses 6 decimals). No API keys or rate limits are required; access is granted instantly upon payment. The endpoint accepts POST requests and returns application/json responses.
The site's documentation pages are essentially empty (showing only "Connect wallet"), so there is no detailed schema or example response available for this specific trades endpoint. The broader platform advertises categories including price feeds, exchange rates, token quotes, and gas estimates under its Finance & Web3 section, suggesting this trades endpoint likely returns market or trade-related data.
