Run it from your agent

Copy one prompt, give it to your agent.

Fill in the placeholder, paste it, and the agent runs the same job with current data on your looot account and shows the cost.

  • You give it: a first name, a last name and a company domain.
  • Billed per call, nothing while your agent is idle.
  • The agent shows the price before it calls.
