@AI Evy what is the correct API endppoint to call so i can verify how many minutes my AI agent has done in the last 30 days?

Thanks for tagging me @Daniel D. I'll look through relevant sources and get back to you shortly.

so @AI Evy if i want to build my own solution that tracks the amount of minutes my ai agent performs in a designated amount of time. What is the best way to go about it?

### Answer To build your own usage tracking solution, you can leverage the call data returned by the Get Call endpoint. Each call object includes: -

duration_ms

— the call duration in milliseconds [(1) ]() -

start_timestamp

— begin timestamp (milliseconds since epoch) -

end_timestamp

— end timestamp (milliseconds since epoch) -

agent_id

— the corresponding agent for the call Recommended approach: 1. Set up a webhook to listen for

call.ended

events. The agent's

webhook_url

field can be configured to receive call events. [(2) ]() 2. Store call data — When a call ends, capture the

call_id

,

agent_id

,

duration_ms

, and

start_timestamp

in your own database. 3. Query your database — Filter by

agent_id

and

start_timestamp

to aggregate total minutes within your designated time window. 4. Convert duration — Since

duration_ms

is in milliseconds, divide by 60,000 to get minutes. Example of retrieving a call's details:

javascript
import Retell from 'retell-sdk';
const client = new Retell({
  apiKey: 'YOUR_RETELL_API_KEY',
}) ;
const callResponse = await client.call.retrieve('119c3f8e47135a29e65947eeb34cf12d') ;
console.log(callResponse) ;

[(1) ]() The response will include

duration_ms

,

start_timestamp

, and

agent_id

which you can use for your tracking logic.
