## When to use
- Get growth or inflation forecasts for a country plan or a budget.
- Find the right IMF code first with `words`, then fetch values.
## When not to use
- Long historical series with many indicators. Use https://skills.duaer.com/world-bank.md.
- Monthly or quarterly data. The DataMapper is yearly.
