DeFi liquidity data for WIF token, paid per-request via x402 on Base network.
What it does
This endpoint at lowpaymentfee.com provides DeFi liquidity data for the WIF (dogwifhat) 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 endpoint accepts POST requests and returns JSON. Payment is settled in USDC on Base (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) at a maximum cost of $0.02 per request (20,000 base units with 6 decimals). The x402 challenge was captured live, confirming the endpoint is operational. The payment timeout is 300 seconds.
Documentation is extremely sparse — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no actual 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 path suggests it returns liquidity information for the WIF token in a DeFi context, but the exact response structure is unknown.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is zero documentation on request parameters, response schema, or what 'liquidity' data is actually returned. Docs pages are empty. This is effectively a stub listing.
