The engine behind the Vidmoat editor, as a REST API: create a project, apply edit commands, render it, read the result. Editing runs through the identical command reducer the editor uses, so anything you can do by hand you can do over HTTP.
curl -X POST https://api.vidmoat.com/v1/projects \

-d '{"name":"My first API edit"}'Sign in with your normal Vidmoat account — there is no separate developer identity. Registering an app and minting test keys is free on any plan.
