I’m new to Prefect, and want to know if Prefect exposes any REST API. I have the frontend UI already and want to figure out a way to talk with Prefect

Hi @Alfie and welcome to the community! Yes, Prefect has a GraphQL API (GraphQL is much more expressive than a REST API and can still be accessed via POST requests). There are currently two options for using the Prefect API: 1.) currently, the open source version of Prefect allows you to host this API locally yourself. In short, if you plan to only run workflows on a local machine this is a viable option. Configuring this to work across machines is non trivial but is possible (e.g., see this blog post: https://medium.com/the-prefect-blog/prefect-server-101-deploying-to-google-cloud-platform-47354b16afe2) 2.) If you want to run workflows in a distributed environment (e.g., kubernetes, multiple cloud environments, multiple machines) but are not interested in the networking complexities of hosting an API yourself, you might consider Prefect Cloud which is a highly available publicly accessible API that Prefect hosts on users’ behalf. You can sign up and get started for free at https://cloud.prefect.io/ Hope that helps!

good to know these, thanks!
