What it does

This endpoint at lowpaymentfee.com provides DeFi liquidity data for USDT, accessible via the x402 payment protocol on the Base network. Each request costs $0.02 in USDC (20,000 base units of USDC on Base, which has 6 decimals). No API keys or rate limits are required — callers simply attach an x402 payment header to a POST request and receive a JSON response.

The endpoint is part of a broader suite of APIs offered by lowpaymentfee.com spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced uniformly at $0.02 per request. The specific endpoint `/api/v1/defi/USDT/liquidity` is not listed on the provider's landing page among the advertised endpoints, though the DeFi/finance category is represented by other endpoints. The exact response schema is not documented — no OpenAPI spec, detailed docs, or example responses were found in the crawl. The docs, pricing, and API pages all returned only a "Connect wallet" prompt with no further content.

Because documentation is essentially absent beyond the x402 challenge and the landing page overview, the precise fields returned by this liquidity endpoint are unknown. Callers should expect a JSON payload related to USDT liquidity metrics, but the structure must be discovered empirically.
