Pay-per-call trade data endpoint on Base via x402, settled in USDC at $0.02/request.
What it does
This endpoint at `/api/v1/trades/60` is part of the lowpaymentfee.com platform, which offers a collection of x402-protocol APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities. All endpoints use the x402 payment protocol on the Base network, accepting USDC (USD Coin) for per-request micropayments with no API keys, no rate limits, and no subscriptions required.
The specific `/api/v1/trades/60` endpoint is labeled "Premium API Access" and accepts POST requests. Based on the x402 challenge, the maximum amount required is 20,000 base units of USDC (6 decimals), which equals $0.02 per request. Payment is made to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on the Base network, with a timeout of 300 seconds. The response MIME type is `application/json`.
The exact data returned by this particular endpoint is not documented in the crawled material — the path suggests trade-related data (possibly a specific trade record with ID 60), but no schema or example response was found. The broader platform advertises categories including finance/price feeds, exchange rates, token quotes, and gas estimates, so this endpoint likely falls within the finance/trading data domain. Documentation pages (`/docs`, `/pricing`, `/README`) all returned only a "Connect wallet" prompt with no substantive content.
