## 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 twelvex-earnings-calendar-517446ce
```

Example prompt: Pull up the earnings calendar for next week — from Monday April 21 to Friday April 25 — so I can see which companies are reporting and plan around them.

## When to prefer this

Use this endpoint when you need a broad calendar view of all upcoming or recent corporate earnings announcements across the market for a date range, rather than looking up a specific company's historical earnings. Prefer this over stock-specific endpoints when planning trades or monitoring market events across multiple companies simultaneously.

## Known failure modes

- Invalid date format returns an error or empty result
- start_date after end_date may return an empty or error response
- Dates too far in the future may return no data if not yet scheduled
- Rate limiting or payment failure (402) if USDC payment is not processed
- Very broad date ranges may return large payloads or be throttled
