## 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 imf-datamapper-series-0ac9d4c1 -d '<json body>'
```

Example prompt: Pull the IMF DataMapper real GDP growth indicator (NGDP_RPCH) for the United States, Germany, and Japan from 2015 to 2025 so I can see which years are forecasts versus actuals.

## When to prefer this

Choose this endpoint when you need structured, per-year economic time-series data from the IMF DataMapper for specific indicators (e.g. NGDP_RPCH, PCPIPCH) across one or more countries, especially when you need clear separation of historical actuals from IMF forecasts. It is ideal for macroeconomic research, country comparison dashboards, and investment analysis pipelines that consume IMF World Economic Outlook-style data programmatically.

## Known failure modes

- Invalid or unrecognized IMF indicator code returns an error or empty series
- Unknown country codes result in missing or empty country-level data
- Year range outside available IMF data returns no data points
- Network or payment (x402) authentication failure prevents response
- Requesting too many countries at once may cause timeout or partial results

## How this service works

Returns one IMF DataMapper indicator (e.g. NGDP_RPCH real GDP growth) for one or more countries, optionally limited to a year range. Output has unit, per-country series of {year, value, forecast_flag}, and a top-level forecast_flag. A point is a forecast when year &gt;= the current UTC year.; Searches

## Output

Returns a structured response containing the indicator's unit label, and for each requested country a time series of {year, value, forecast_flag} objects. The top-level response also includes a forecast_flag indicating whether the most recent data point is projected. Any year >= the current UTC year is treated as a forecast.
