What it does

This endpoint at lowpaymentfee.com provides "Premium API Access" via the x402 payment protocol. The specific path `/api/v1/trades/14` suggests a trades-related data endpoint, though the exact response payload is not documented. The provider operates a broader platform offering Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure utility APIs, all priced at $0.02 per request settled in USDC on the Base network.

The endpoint accepts POST requests and requires an X-PAYMENT header conforming to x402 version 1. Payment is settled in USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base, with a maximum amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals). There are no API keys, no rate limits, and no subscription commitments — each call is independently paid.

Documentation is extremely sparse. The crawled docs, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical detail. The output schema and response format for this specific trades endpoint are not documented anywhere in the available material.

The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation of request parameters, response schema, or what 'trades/14' actually returns. Docs pages are empty beyond a wallet connect prompt.

Warnings

  • The meaning of '/trades/14' (trade ID? category?) is unclear
  • All docs/pricing/README pages render only 'Connect wallet' with no technical content
  • Output schema and example responses are entirely undocumented
