Introduction
HollrAI is a dedicated platform for building and deploying AI call agents for real business workflows. You can configure an agent, choose its voice and languages, connect the systems it needs, and deploy it from the HollrAI platform at app.hollr.ai.
The API is the programmatic layer on top of that platform. Its purpose is to let your application trigger AI calls programmatically and read the resulting conversation data, using an agent and campaign you’ve already configured on the platform.
Trigger a single outbound call or a batch of calls from your application
Read the records created from calls, including transcripts and call insights
How HollrAI fits into your application
Campaigns and agents are set up once, in the HollrAI platform. Your application then uses the API to trigger calls and read the results.
- Create a campaign in HollrAI. Sign in to app.hollr.ai and create a campaign, for example “Lead Qualification”. A campaign is the container for a calling workflow.
- Create an agent under that campaign. Still in the platform, configure the AI voice agent attached to the campaign — its opening message, system prompt, voice, and languages.
- Trigger calls from your application. Your backend sends a phone number, the campaign ID, and optional metadata to the Calls API.
- Read the result. After the call, use the Conversations API to retrieve the conversation record, transcript, summary, sentiment, recording information, and other available call data.
You do not need to rebuild any of the campaign or agent configuration inside your application. The platform is where campaigns and agents are built; the API gives your application a reliable way to trigger calls and read what happened.
