# Start simulated calls

POST https://api.levrage.ai/v1/agents/{agent_id}/voice-simulations
Content-Type: application/json

Simulated PHONE calls to the agent with the callers you describe: a real voice, interruptions and
background noise, graded against your rubric. Returns a run id at once; the calls take a few minutes
(GET /v1/voice-simulations/\{run\_id}). Uses the monthly simulated-minutes allowance.
