Our Public API
Embed Allegrow's powerful risk analysis directly into your applications. Our API gives you programmatic access to the same 'Safe' or 'Unsafe' verdicts that power our platform.
Our Public API
Go beyond simple validation. Use our API to enrich your products with advanced email verification, build custom data hygiene workflows, and protect your users from reputation-damaging contacts at scale.
Core API Capabilities
The Allegrow API provides direct, programmatic access to our core risk analysis engine. It’s a fast, reliable, and straightforward way to integrate our high-accuracy email verification system. Key functions include:
- Get Definitive 'Safe/Unsafe' Verdicts: No more "risky" or "unknown." Programmatically determine if a contact is safe to email, even on catch-all domains.
- B2B-Optimized Risk Analysis: Purpose-built for stricter B2B spam filters, with advanced detection for risks unique to business environments, including catch-all and role-based addresses.
- Access Granular Risk Factors: Go beyond the verdict. Fetch the specific data points that identify a contact as a spam trap or known complainer.
- Catch-All Resolution: Our API provides individual mailbox verification on catch-all domains, a feature legacy APIs lack.
- Automate Complex Hygiene: Use our data to build robust, custom workflows that keep your contact databases perpetually clean.
- Synchronous Validation: For on-demand checks, like web forms, receive an instant 'Safe' or 'Unsafe' validation result in the same API call.
- Asynchronous Validation: For large datasets, submit thousands of validation requests at once and receive the results efficiently via webhook when ready.
- Flexible & Scalable: Our API is built to handle everything from single lookups to batch analysis of millions of contacts.
Our API is built for performance and reliability, giving you the data you need with no unnecessary complexity. See the full documentation for all endpoints and code samples.
