Which online consultant with api to choose?

Question

Computer networks

Good afternoon.
The task is to select an online consultant with a developed API for exchanging data with the site. For example, you need to start a chat window with a given text on an event on the site (a question about a specific product, etc.). I would also like full customization of the appearance of the button and chat.
I saw similar functionality at intercom.io . But the price and lack of localization confuses.
