Defastra is a powerful tool for fraud detection and risk analysis, offering deep verification of emails and phone numbers. With Relevance AI, you can leverage this data to create smarter, more responsive AI Agents that enhance your decision-making processes.



Defastra provides robust fraud detection and risk analysis through deep email and phone verification. Relevance AI amplifies these capabilities by enabling intelligent AI Agents to analyze and act on the enriched data effectively.
Real-Time Risk Intelligence
Empowers AI agents with instant fraud detection capabilities and risk assessment insights across multiple digital channels.
Identity Verification Mastery
Enhances agent capabilities with advanced document verification and biometric matching for seamless identity confirmation.
Adaptive Risk Scoring
Grants agents the ability to dynamically adjust risk assessments based on real-time transaction patterns and user behavior.
Relevance AI seamlessly integrates with Defastra to enhance your fraud detection workflows.
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 Defastra account
- A Relevance AI account with access to your project settings
- Authorization (you'll connect securely using API keys—no sensitive info stored manually)
Security & Reliability
The integration between Defastra and Relevance AI leverages secure OAuth authentication, ensuring that only authorized workflows can access your fraud detection and risk analysis capabilities. Relevance AI manages API operations (like POST requests for deep email and phone checks) seamlessly in the background, allowing you to focus on identifying potential fraud patterns without worrying about errors, formatting, or limits.
With built-in validation and type conversion, your workflows will run smoothly, even when dealing with varying data formats. This integration provides comprehensive fraud detection, scalable data enrichment, and flexible timeout controls to balance detail and speed, all while keeping your data organized with custom labels.
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 Defastra + Relevance AI integration without writing code:
- Start with a clear data structure: Use descriptive labels for your requests to keep track of different verification batches.
- Utilize timeout settings wisely: Choose the appropriate timeout level based on your needs—`normal` is recommended for a balance of speed and detail.
- Test with sample data: Run initial checks using test emails and phone numbers to ensure everything is functioning correctly before scaling.
- Implement error handling: Always include error handling in your requests to manage authentication errors and timeouts effectively.
- Monitor API usage: Keep an eye on response times and rate limits to optimize your integration and avoid throttling issues.
