x402-payable token data endpoint for CFX on Base, $0.02 per request via USDC.
What it does
This endpoint at lowpaymentfee.com provides token data for CFX (Conflux) via an x402 payment-gated API. It is part of a broader platform offering dozens of endpoints across data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request, settled in USDC on the Base network.
The specific endpoint `/api/v1/tokens/CFX` sits under the Finance & Web3 category of the platform. While the exact response schema is not documented, the endpoint path strongly suggests it returns token-level information for the CFX token (likely price, metadata, or market data). The x402 challenge confirms the endpoint is live, accepts POST requests, and requires a payment of 20,000 base units of USDC (0x8335…) on Base — which equals $0.02 given USDC's 6 decimals.
The platform advertises no API keys, no rate limits, and instant access. Authentication is handled entirely through x402 payment headers. Documentation beyond the landing page is essentially empty (all subpages just show "Connect wallet"), so there is no detailed schema, example request/response, or parameter documentation available. The endpoint is confirmed live via a valid 402 challenge.
