What getCurrencyVolatilityForecast does on API Ninjas
AI agents call getCurrencyVolatilityForecast to retrieve information from API Ninjas without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
pair | string | Yes | Currency pair in ABC_DEF form (e.g. EUR_USD). Both must be supported fiat currency codes; ZWG, BTC, and XAG are not supported. |
lambda | number | — | EWMA decay factor (only used when method=ewma). Defaults to 0.94. Must be between 0.80 and 0.99. |
method | string | — | Forecast method: garch_11 (default) or ewma. If a GARCH fit does not converge the response falls back to EWMA. |
horizon | string | — | Comma-separated forecast horizons in trading days (e.g. 1,5,21,63). Defaults to 1,5,21,63. |
day_count | integer | — | Annualization factor: 252 trading days (default) or 365 calendar days. |

Why getCurrencyVolatilityForecast is rated Low
Even though getCurrencyVolatilityForecast only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
