## 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 cambrian-x402-api-aerodrome-v3-pool-lookup-22d0ddf7
```

Example prompt: Pull the Aerodrome V3 pool data for the USDC/WETH pair on Base — I need the current liquidity, fee tier, and tick info.

## When to prefer this

Choose this endpoint when you need real-time Aerodrome V3 pool data on EVM chains (particularly Base) in a pay-per-use model without API key setup. Prefer it over self-hosted RPC calls when you want managed, metered access to Aerodrome DEX data with x402 micropayment billing.

## Known failure modes

- Payment not included or invalid x402 payment header returns 402 Payment Required
- Invalid or missing query parameters returns an empty array or 400 error
- Pool not found for given token pair returns empty array
- Chain or contract not supported returns an error
- Rate limiting or upstream RPC failure returns a 5xx error
