## 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 zumpay-aero-signals-whale-api-4f967493
```

Example prompt: Pull the latest whale signals from the Aerodrome Base pools right now — I want to see who's making big liquidity moves on the DEX.

## When to prefer this

Choose this endpoint when you need real-time, on-chain whale and large liquidity movement signals specifically for Aerodrome DEX pools on the Base network, paid per-call via x402 micropayments — ideal for AI agents that need fresh DeFi intelligence without a subscription commitment.

## Known failure modes

- 402 Payment Required if x402 micropayment header is missing or insufficient
- Empty data array if no whale signals detected in the current window
- Invalid or malformed properties filter returning no results
- Network timeout if Base RPC or indexer is slow
- Rate limiting if query volume exceeds plan thresholds
