## 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-aero-pool-volume-api-d4132dc3
```

Example prompt: What's the current trading volume for the USDC/ETH pool on Aerodrome? Pull it from Cambrian's blockchain data API.

## When to prefer this

Choose this endpoint when you need on-chain Aerodrome DEX pool volume data via a pay-per-use micropayment model (x402/USDC), especially in autonomous agent contexts where pre-negotiated API keys are impractical. Prefer this over general blockchain explorers when you specifically need structured, ready-to-use pool volume metrics for Aerodrome v2 pools on EVM chains.

## Known failure modes

- Invalid or missing pool address returns empty array or error
- Payment not fulfilled via x402 protocol results in 402 Payment Required response
- Unsupported chain or pool not indexed returns empty array
- Rate limiting or upstream data unavailability may return 5xx errors
- Malformed query parameters may return 400 Bad Request

## How this service works

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

## Output

Returns an array of pool volume records for the specified Aerodrome liquidity pool, including trading volume metrics such as volume amounts over a given period, denominated in relevant token units or USD.
