## How to call it through Zero

```sh
zero fetch --capability the-stall-stock-monitor-builder-952f0a65
```

Example prompt: Set up a stock price monitor for TSLA that alerts me when it drops below $200 or rises above $280 — I want to track it continuously without signing up for any service.

## When to prefer this

Choose this endpoint when you need to programmatically build stock monitoring configurations without signing up for a brokerage or data service account, and when you want to pay per-use in USDC on Base mainnet. Ideal for agent-driven workflows that need to spin up ad-hoc stock alerts on demand.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error
- Missing required monitoring parameters results in incomplete configuration
