The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
convert_currency Convert an amount between currencies ~144
Converts an amount from one currency to another using the latest rate, or the rate on a past date if 'date' is given. Returns the rate used, the given amount, and the converted amount. Starter plan and above (any paid plan).

get_fluctuation Get exchange rate fluctuation ~242
Returns how currencies moved between two dates: start rate, end rate, absolute change, and percent change for each symbol against the base. Note the sign convention: change = startRate - endRate, so a POSITIVE change means fewer units per base, i.e. the symbol currency strengthened against the base, and a NEGATIVE change means the rate rose and the symbol currency weakened. Professional plan and above.
| Name | Type | Req | Description |
|---|---|---|---|
| base | string | – | Base currency code the rates are expressed against (e.g. 'EUR'). Default is USD. Changing the base requires the Starter plan or above (any paid plan). |

get_historical_rates Get historical exchange rates ~187

ip_to_currency Convert to the local currency of an IP address ~128
Resolves the local currency from an IP address's geolocation and converts an amount into it using the latest rate. Useful for localizing prices for a visitor. The target currency is returned in the 'to' field. Growth plan and above.
| Name | Type | Req | Description |
|---|---|---|---|
| amount | number | – | Amount to convert. Must be greater than 0. Default is 1.0. |

list_currencies List supported currencies ~199
Returns the currencies supported by CurrencyFreaks: 1000+ fiat currencies, cryptocurrencies, and precious metals (XAU gold, XAG silver, XPT platinum, XPD palladium). Use it to find a currency code before calling rate or conversion tools. No API key needed. By default returns a compact code → name map. Pass 'search' to filter by code, name, or country (e.g. 'rupee', 'PK', 'bitcoin'). Pass detailed=true for country, status (AVAILABLE/DEPRECATED), and the availableFrom/availableUntil date range of historical data per currency — combine with 'search' because the full detailed catalogue is very large.
| Name | Type | Req | Description |
|---|---|---|---|
| detailed | boolean | – | Return full details per currency (country, status, historical availability range, icon). Default false. |
| search | string | – | Case-insensitive substring to match against currency code, name, or (with detailed=true) country name. |
