Where can i find social media bot with API support ?

Bot with the possibility of controlled by API, it exists ?
Bot with possibility of controlled by API, it exists?

I do not want to manually schedule posts to post, to automate as much as possible it is more preferable to define your own tool

If you want something control by API, you have severe restrictions on what you can and can't do.
The price for it is also much higher than most bots I've seen.

Later is an example of a scheduling tool that uses IG API but I find their pricing way too high for what they offer.
