A worker is an AI colleague in your workspace. Every workspace starts with Taylor, the AI account executive (follow-ups, proposals, scheduling), and Parker, the AI platform admin (keeps company, people and deal records current after every email and meeting). Custom workers take any role you describe in plain words. Workers appear where your team works: as task assignees, in Ask Heliyos, and as the actor on the changes they make.

What workers know

Workers read your workspace’s knowledge base on every run: the business context, your products, the pain points they solve, your value proposition, what makes a lead worth pursuing, and any custom entries your team adds, such as pricing or competitors. Read and change it with Get the knowledge base and Update the knowledge base. Files your workers read are files with kind knowledge_base.

Three ways to start work

Each start creates a run. Follow it with Get a run, which can wait up to 30 seconds for a change, or list runs with List runs.

Run lifecycle

  • queued and running move on their own. Poll them.
  • awaiting_approval, paused, waiting and scheduled wait on a person or a time. Polling will not move them.
  • completed carries the result in output. failed carries an error.

Review keeps people in control

Consequential actions, such as sending an email or changing a deal, wait for approval unless your workspace’s autopilot settings allow them. The run shows awaiting_approval and lists what is waiting in reviews. A person approves or rejects in Heliyos, with the worker’s evidence and reasoning next to the action. The API can list reviews and approve or reject one, so give that power only to systems your team trusts to decide.

Credits

Runs that call custom workers use credits. Built-in workers and the planning step are free. Check usage with List credit usage. When the workspace is out of credits, starting a task run answers 409 CONFLICT.
Starting a run makes workers act in your workspace. Start with review on, and widen autopilot only after you trust a worker with a kind of action.
