DeFi liquidity data for BAT token, paid per-request via x402 on Base network.
What it does
This endpoint at lowpaymentfee.com provides DeFi liquidity data for the BAT (Basic Attention Token) via a POST request. 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. All endpoints use the x402 payment protocol on the Base network, settling in USDC.
The specific endpoint `/api/v1/defi/BAT/liquidity` returns JSON data related to BAT liquidity in DeFi contexts. The x402 challenge confirms the endpoint is live, accepting payments of up to 0.02 USDC (20,000 base units of USDC with 6 decimals) per request to a specified wallet address. The payment scheme is "exact" with a 300-second timeout.
Documentation is extremely sparse — the provider's docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema, and no usage examples available from the crawled material. The endpoint name and path suggest it returns liquidity metrics for BAT, but the exact response structure is unknown. The provider advertises no API keys, no rate limits, and instant access across all their endpoints.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC per request), but there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no examples. The actual data returned is entirely unknown, making this effectively a stub listing.
