MINA liquidity data via x402 micropayment on Base — $0.02 per request, no API key needed.
What it does
This endpoint at lowpaymentfee.com provides DeFi liquidity data for the MINA token. It is part of a broader platform offering data analytics, AI/ML inference, finance/Web3, and infrastructure APIs, all gated behind the x402 payment protocol on the Base network. Each request costs $0.02 in USDC (the x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC, which has 6 decimals, equaling $0.02).
The endpoint accepts POST requests and returns JSON. No API key or account registration is required — callers pay per request by attaching an X-PAYMENT header with a valid x402 payment proof. The platform advertises no rate limits and instant access. Payment settles on the Base L2 network using the USDC contract at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned 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 proper 402 challenge), but the actual data shape and coverage for MINA liquidity are unknown.

Quality
The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, and all documentation pages returned only 'Connect wallet' with no useful content. The actual data returned by this endpoint is entirely unknown.
