DeFi liquidity data for CAKE token, paid per-request via x402 on Base network.
What it does
This endpoint at lowpaymentfee.com provides DeFi liquidity data for the CAKE token (PancakeSwap). It is part of a broader API platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure endpoints, all priced at $0.02 per request with no API keys, no rate limits, and no commitments.
The specific endpoint `/api/v1/defi/CAKE/liquidity` is accessed via HTTP POST and returns JSON. Payment is handled through the x402 protocol on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The max amount required is 20,000 base units of USDC, which equals $0.02 (USDC uses 6 decimals). The payment timeout is 300 seconds.
Documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional content. There is no OpenAPI schema, no request/response examples, and no description of what fields the liquidity endpoint returns or what parameters it accepts. The endpoint is confirmed live via a valid 402 challenge, but the actual data quality and response format remain unknown.
