x402-gated trade data endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides premium API access to trade data via the x402 payment protocol. The specific resource `/api/v1/trades/100` appears to serve trade-related information (likely for a specific trade or asset ID 100), payable per-request in USDC on the Base network.
The provider operates a broader platform offering multiple API categories including data & analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are priced at $0.02 per request with no API keys, no rate limits, and no minimum commitments required. Payment is handled entirely through the x402 protocol using USDC on Base.
The x402 challenge confirms the endpoint is live and accepts POST requests. The max amount required is 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. The payment is settled to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a timeout of 300 seconds. No detailed documentation, request/response schemas, or example payloads were available from the crawled pages — the docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content.

Quality
The x402 challenge is live and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI schema, no request/response examples, no documentation beyond a landing page listing, and the specific behavior of /api/v1/trades/100 is undocumented. This is effectively a stub listing.
