DOGE liquidity data via x402 micropayment on Base network, $0.02 per request.
What it does
This endpoint at lowpaymentfee.com provides DeFi liquidity data for DOGE (Dogecoin) via the x402 payment protocol. It is part of a broader suite of pay-per-call APIs offered by the same provider, spanning data analytics, AI/ML inference, finance, crypto, and utility services. Each request costs $0.02, settled in USDC on the Base network with no API keys, rate limits, or upfront commitments required.
The endpoint accepts HTTP POST requests and returns JSON. The x402 challenge was successfully captured, confirming the endpoint is live. The payment is made to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02.
Documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI schema, no request/response examples, and no description of what fields the liquidity endpoint accepts or returns. The endpoint's actual behavior (e.g., what liquidity metrics it provides for DOGE, which DEXs or pools it covers) is unknown from the available material.
