About

CurrencyAPI (BYOK) lets an AI assistant read your own CurrencyAPI data through the CurrencyAPI API with a key you supply (CurrencyAPI key). Read-only: 8 tools (get_latest_rates, get_historical_rates, convert_currency, get_pair_rate, get_fluctuation, get_central_bank_rates, list_currencies, get_quota_status). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.currencyapi.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by CurrencyAPI. CurrencyAPI and its logos are trademarks of their owners and are used only to say which service the connector works with.

Sources: Live from the CurrencyAPI API (api.currencyapi.com) with a BYOK key; documentation: https://currencyapi.com/docs. Endpoints checked against that documentation on 2026-10-16.

BYOK: bring your own keyThis connector uses your own CurrencyAPI CurrencyAPI key. Create one at https://app.currencyapi.com/api-keys, with the fewest permissions it needs (read-only if the provider offers it). Your assistant sends it in the X-Upstream-Key header with every request. It is used for that one call only: never stored, logged or cached, and only ever sent to CurrencyAPI. Revoke it at the provider whenever you like. Unofficial connector: not affiliated with CurrencyAPI.
