Query DeFi liquidity pool data (prices, TVL, volumes, fees) across Arbitrum, Base, and Ethereum via x402.
What it does
This x402-gated endpoint from Nacian provides detailed information about specific liquidity pools across multiple EVM chains. According to the listing description, it covers Arbitrum, Base, and Ethereum, returning token prices, TVL, volumes, fees, and other pool metrics. Supported exchanges include Uniswap V2/V3/V4, PancakeSwap V2, SushiSwap V2/V3, and Camelot V3, depending on the chain.
Nacian's broader platform is an AI-powered DeFi analyzer that translates natural-language questions into protocol queries. The company also offers a web-based analyzer with alert functionality and data export. This particular endpoint appears to be a standalone REST API for pool information, intended for programmatic access by agents or developers who need structured pool data without using the conversational interface.
Important caveat: during probing, the endpoint returned HTTP 404 on both GET and POST requests rather than the expected 402 payment challenge. This means the endpoint may have been moved, renamed, or is not currently live at the advertised URL. The Nacian docs page at /docs also returns 404, and the site's robots.txt disallows /api/. No OpenAPI schema or x402 challenge details (price, token, network) were captured, so pricing and request/response formats cannot be confirmed.
