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/2` is part of the lowpaymentfee.com platform, which offers a collection of x402-protocol APIs spanning data & analytics, AI/ML, 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 commitments required.
The specific `/api/v1/trades/2` endpoint is listed under "Premium API Access" and accepts POST requests. The x402 challenge indicates a maximum cost of 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 endpoint returns `application/json` responses.
Note that while the provider's landing page lists many API categories (analytics, AI, finance, infrastructure), the specific functionality of this particular trades endpoint is not well-documented. The endpoint path suggests it returns trade-related data (possibly financial or crypto trade information), but no request/response schema, parameter documentation, or example payloads are available from the crawled material. The docs, API, pricing, and README pages all rendered only a "Connect wallet" prompt with no substantive content.

Quality
The endpoint is live (402 challenge confirmed) with clear pricing ($0.02 USDC on Base), but there is no request/response schema, no parameter documentation, no examples, and the docs pages are empty. The actual functionality of '/api/v1/trades/2' is unclear beyond the generic 'Premium API Access' label.
