​
Creating a developer account

To get started, sign up on the developer portal. Enter your phone number and verification code. Finally, once your developer portal loads, go to the Send phone call page.

​
Sending your first phone call

Although Luly is an API-first platform, the send phone call page provides a simple interface for quickly testing calls. On the left side you can adjust the call options and on the right hand side you can see how the code updates. Once you’re satisfied with a call, copy the code on the right side (in Javascript, Python, or cURL) and add it to your application.
1

Enter your phone number

In the Phone Number field,enter your own phone number.
2

Write your prompt

For the task box either select one of the example prompts or write your own. For more instrucionts about prompting your AI phone agent, read this blog post
3

Send the call

Scroll to the bottom of the page, and press the Send call button. Note calls are charged at $0.12/minute, billed to the exact second.
To send a phone call programatically, read the API reference.

​
Testing your phone agent

Once you’ve sent your first phone call, the next step is to test and improve the outputs from your phone agent. One way to test your agent is to send yourself test calls. A faster way, however, is to use the Luly AI testing suite.
1

Set up the test suite

Select the model and language and insert your current prompt into the task box.
2

Write a message

Start messaging your phone agent. Act like you’re the person receiving the call, and purposefully ask edge-case questions to throw the phone agent off.
3

Update the prompt

Based on the responses you receive, update the instructions in the prompt.
