Synthesia (BYOK) lets an AI assistant read your own Synthesia data through the Synthesia API with a key you supply (Synthesia API key (Legacy v2 scope)). Read-only: 5 tools (list_videos, get_video, list_templates, get_template, get_credit_balance). 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.synthesia.io. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Synthesia. Synthesia and its logos are trademarks of their owners and are used only to say which service the connector works with.
Sources: Live from the Synthesia API (api.synthesia.io) with a BYOK key; documentation: https://docs.synthesia.io/reference/video-api-introduction. Endpoints checked against that documentation on 2026-10-16.
