## 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-ada05457
```

Example prompt: Pull the earnings calendar from TwelveX for the next two weeks — from July 14 to July 28 — so I can see which companies are reporting their quarterly results.

## When to prefer this

Use this endpoint when you need a calendar view of upcoming or past corporate earnings announcements across all stocks, particularly when planning trades or research around earnings season. Prefer this over individual stock lookups when you need a broad date-range sweep of all reporting companies.

## Known failure modes

- Invalid date format returns an error — dates must be in YYYY-MM-DD format
- Empty result if no earnings are scheduled in the requested range
- Overly wide date range may return very large payloads or be rejected
- Payment failure (402) if USDC balance is insufficient
- Service unavailable if Twelve Data upstream is down
