CallerAPI is a powerful platform that offers caller identification and phone number enrichment through a REST API. With Relevance AI, you can enhance these features, allowing AI Agents to utilize caller data for more effective and automated interactions.



CallerAPI provides robust caller identification and phone number enrichment through its REST API. Relevance AI amplifies these capabilities by enabling intelligent AI Agents to leverage this data for smarter decision-making and automation.
Real-Time Voice Intelligence
Agent gains instant access to caller data and insights during live conversations, enabling smarter interactions
Conversational Analytics Mastery
Processes and learns from call patterns to continuously improve interaction quality and outcomes
Predictive Response Capability
Anticipates caller needs through historical data analysis and behavioral patterns
Relevance AI seamlessly integrates CallerAPI into your workflows, enhancing caller identification and data enrichment processes.
What you’ll need
You don't need to be a developer to set up this integration. Follow this simple guide to get started:
- A Relevance AI account
- An Airtable account with access to the base and table you'd like to use
- Authorization (you'll connect securely using OAuth—no sensitive info stored manually)
Security & Reliability
The CallerAPI integration utilizes secure OAuth authentication, ensuring that only authorized workflows can access caller identification and phone number enrichment data. Relevance AI manages API operations (such as GET requests for phone number information and profile pictures) seamlessly in the background—eliminating concerns about errors, formatting, or rate limits.
With built-in validation for phone numbers in E.164 format and automatic handling of API responses, your applications can enrich caller data reliably and efficiently, even when data formats vary.
No training on your data
Your data remains private and is never utilized for model training purposes.
Security first
We never store anything we don’t need to. The inputs or outputs of your tools are never stored.

To get the most out of the CallerAPI + Relevance AI integration without writing code:
- Start with a clean data structure: Ensure phone numbers are stored in E.164 format for consistency and accuracy.
- Use pre-built workflows: Leverage Relevance AI's templates for retrieving caller information and enriching data seamlessly.
- Connect carefully: Verify that you have the correct OAuth credentials and permissions set up during the integration process.
- Test before scaling: Conduct tests with sample phone numbers to validate responses and avoid issues in production.
- Monitor API usage: Keep an eye on your API call limits and response times to ensure smooth operation and avoid throttling.
