## 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-v2-liquidity-pools-99dbf7bc
```

Example prompt: Pull the current list of Aerodrome V2 liquidity pools on Base from Cambrian's x402 pay-per-use API so I can analyze TVL and available trading pairs.

## When to prefer this

Choose this endpoint when you need structured, up-to-date Aerodrome V2 pool data on EVM chains without managing your own RPC infrastructure, and when a pay-per-use micropayment model (via x402) is acceptable. Ideal for autonomous agents that need on-demand DeFi pool data without subscription overhead.

## Known failure modes

- Missing or invalid x402 payment header returns 402 Payment Required
- Insufficient USDC balance causes payment failure and blocked request
- Invalid or unsupported query parameters may return empty array or 400 error
- Network or RPC issues with the underlying EVM chain may cause stale or unavailable data
- Rate limiting if payment is not processed correctly

## How this service works

Pay-per-use blockchain and social data for autonomous agents.

## Output

Returns a JSON array of Aerodrome V2 pool objects, each containing pool-level data such as pool addresses, token pair details, fee tiers, liquidity metrics, and other on-chain pool attributes relevant for DeFi analysis and agent decision-making.
