Example prompt: Find all Uniswap V3 pools on Ethereum that contain USDC at contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48, ranked by total value locked, so I can see the best liquidity options and fee tiers available.

## When to prefer this

Use this endpoint when you need to discover Uniswap V3 liquidity pools for a specific ERC20 token on Ethereum — particularly for DEX routing decisions, liquidity analysis, or finding the best fee tier for a swap. Prefer this over generic DeFi data providers when you need TVL-ranked pool data directly from the Uniswap V3 subgraph without building your own subgraph query.

## Known failure modes

- Invalid or non-Ethereum token contract address returns empty results or error
- Token with no Uniswap V3 pools returns empty list
- Subgraph data lag means very recently created pools may not appear
- Rate limiting or payment failure returns 402 or 429 error
- Malformed address (wrong checksum, wrong length) returns validation error

## How this service works

Uniswap V3 pools on Ethereum that contain a given token, by token contract address, ranked by total value locked, each with pair, fee tier and TVL, from a subgraph behind an API key. For finding where a token has liquidity. find pools, token liquidity pools, pools for token, where to trade, dex routing Accepts payment on Base or Solana — either network works.

## Output
