## 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 claw402-twelve-data-economic-calendar-b700b054
```

Example prompt: Show me all high-importance economic events for the United States from January 13 to January 20, 2025 — things like GDP releases, Fed meetings, or jobs reports.

## When to prefer this

Use this endpoint when you need structured economic calendar data — scheduled releases, central bank decisions, or macro indicators — for a specific country and date window, especially in a crypto-native agent context where you want to pay per-call in USDC without API key management. Prefer this over direct Twelve Data access when avoiding registration overhead is a priority.

## Known failure modes

- Empty data array if no events match the specified date range or country
- Payment failure if wallet lacks sufficient USDC balance (402 response)
- Invalid date format causing a bad request error
- Unrecognized country code or importance value returning empty results
- Network timeout or provider-side outage from Twelve Data

## How this service works

Backed by vergex.trade. Pay for any API with USDC. No API keys. No registration. Just a wallet.

## Output

A JSON object containing a list of economic calendar events matching the specified filters, including event names, dates, countries, and importance levels. The response has a status code field and a data array with event entries.
