The Manus API v2 at https://api.manus.ai/v2 starts agent tasks and reads their progress. Methods are named like task.create; the response's task_id is what you poll.
Create a key in your Manus account's API settings and send it as the x-manus-api-key header. In the examples it's written {{MANUS_API_KEY}}.
