## How to call it through Zero

```sh
zero fetch --capability nacian-finance-fb591410
```

Example prompt: Show me the top liquidity pools by TVL on Arbitrum for ETH and USDC — I want to see pool IDs, fee tiers, and how much value is locked in each.

## When to prefer this

Use this endpoint when you need a ranked list of the most liquid pools by TVL across Arbitrum, Base, or Ethereum, especially when you want to discover the best venues for swapping or providing liquidity for a token pair. Prefer this over the detailed pool info endpoint when you need broad discovery rather than deep metrics on a known pool, and over the APR endpoint when TVL ranking rather than yield is the primary concern.

## Known failure modes

- Unsupported chain specified — only Arbitrum, Base, and Ethereum are supported
- Invalid or unrecognized token addresses return empty or error response
- No pools found for the specified token pair on the given chain
- Payment not processed — x402 payment required at $0.01 USDC per call
- Rate limiting or upstream data provider unavailability causing timeout

## How this service works

Access top liquidity pools by TVL across multiple chains (Arbitrum, Base, Ethereum). Tokens do not necessarily need to be token0 and token1 respectively in the pool, they are reordered automatically.

## Output

Returns a list of top liquidity pools sorted by TVL for the specified chain and optional token pair, including pool ID, fee tier, raw liquidity value, total USD value locked, and per-token TVL amounts, along with chain metadata, protocol name, and response timestamp.
