## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability canaryguard-uniswap-aerodrome-pool-state-auditor-3b022ae2
```

Example prompt: Can you audit the liquidity pool at 0x4e68Ccd3E89f51C3074ca5072bbAC773960dFa36 on Base and tell me the tick depth, fee tier, price impact in bps, and whether there's a high LP concentration rug risk? Use USDC as the quote token.

## When to prefer this

Choose this endpoint when you need on-chain liquidity risk intelligence specific to Uniswap V3/V4 or Aerodrome pools on Base, particularly when evaluating price impact before a swap, assessing LP concentration rug risk before providing liquidity, or auditing pool health as part of a DeFi investment workflow. It is more specialized than generic DEX aggregators and provides rug-risk scoring not available from standard pool explorers.

## Known failure modes

- Invalid or non-existent pool/token address returns an error or empty result
- Address is on a chain other than Base — not supported
- Pool has no liquidity or is newly created — depth metrics may be zero or unavailable
- Rate limiting or payment failure if x402 payment is not properly handled
- Malformed address format causes a validation error

## How this service works

Audits Uniswap V3/V4 and Aerodrome liquidity pools on Base, returning tick liquidity depth, fee tier, price impact bps, and LP concentration rug-risk scores.

## Output

Returns tick liquidity depth across price ranges, the pool's fee tier, estimated price impact in basis points for a swap, and an LP concentration rug-risk score indicating whether liquidity is dangerously concentrated in a few wallets.
