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 on your looot account and shows the cost. It can take a whole list, which the box above does not.

  • You give it: a zip or postal code, or an address, and a country code.
  • Billed per call, nothing while your agent is idle.
  • The agent shows the price before it calls.
