DeFi liquidity data for MNT (Mantle) via pay-per-call x402 on Base network.
What it does
This endpoint at lowpaymentfee.com provides DeFi liquidity information for the MNT (Mantle) token. It is part of a broader platform offering data & analytics, AI/ML, finance/Web3, and infrastructure APIs, all accessible via the x402 payment protocol on the Base network with no API keys or rate limits required.
The specific endpoint `/api/v1/defi/MNT/liquidity` accepts POST requests and returns JSON. Payment is settled in USDC on Base (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 USD — consistent with the platform's uniform $0.02/request pricing advertised on its landing page.
Documentation is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the liquidity endpoint accepts or returns. The endpoint is confirmed live (returns a valid x402 402 challenge), but the actual data payload structure must be discovered by making a paid call. The platform advertises no API keys, no rate limits, and instant access.
