## 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 market-calendar-api-next-us-economic-indicator-release-c6c52ef0
```

Example prompt: When is the next CPI release — give me the exact date and time in ET and UTC, and tell me what reference period it covers.

## When to prefer this

Choose this endpoint when you need the single next upcoming release for one or more specific US macro indicators with exact ET/UTC times from official government calendars. Prefer this over the date-range listing endpoint when you only need the immediate next release and don't need a full schedule. Ideal for pre-trade checks, alert scheduling, or quickly answering 'when is the next X report?' without parsing a list.

## Known failure modes

- Invalid or unsupported indicator code returns an error (only CPI, NFP, PPI, GDP, PCE accepted)
- Date parameter in wrong format (not YYYY-MM-DD) returns a validation error
- No upcoming release found for the given indicator within the calendar window
- Service unavailable if the underlying BLS/BEA calendar data source is temporarily inaccessible
- Rate limiting or payment failure (x402) if USDC balance is insufficient

## How this service works

Returns the next scheduled release of a US economic indicator (CPI, NFP, PPI, GDP, PCE) with exact time in ET and UTC and the reference period, from official BLS/BEA calendars.

## Output

A structured response containing the indicator name, the next scheduled release date, exact release time in both Eastern Time (ET) and UTC, and the reference period (e.g., 'June 2025') the data covers, sourced from official BLS/BEA release calendars.
