Does Google have an API to detect text containing watermarks?

I would like to ask, does Google have an API to detect text containing watermarks?

The channel where I learned this information is: SynthID: Tools for watermarking and detecting LLM-generated Text  |  Responsible Generative AI Toolkit  |  Google AI for Developers

Hi @lidashuaiqi ,
Google does not offer a public API specifically designed to detect watermark text in documents or images.
Google Cloud APIs Documentation.
Thanks!
