What makes BlitzAPI different from other B2B data providers?

BlitzAPI distinguishes itself through an API-first architecture built for seamless integration and a fundamental commitment to verified outcomes. Unlike providers that prioritize data volume, BlitzAPI focuses on deliverability and accuracy first, offering features like high-accuracy catch-all validation and a "pay only for verified results" model. It is designed as flexible infrastructure that adapts to your workflow, not the other way around.

How does the "pay only for verified results" pricing work?

BlitzAPI operates on a transparent credit system where you are only charged for successful, verified data retrievals. For instance, if you request an email enrichment and a verified, deliverable email is returned, one credit is consumed. Failed lookups or unverified data do not deplete your credits, ensuring you only pay for high-quality information that directly contributes to your GTM efforts.

Can BlitzAPI integrate with our existing tech stack?

Absolutely. BlitzAPI is engineered as a developer-friendly, REST API service designed for easy integration into any existing workflow or technology ecosystem. It can connect directly with your CRM (like Salesforce or HubSpot), marketing automation platforms, internal databases, and custom applications, serving as the unified data engine for your entire GTM operation.

What is the accuracy rate for email data and validation?

BlitzAPI maintains an exceptional email deliverability rate of over 98%. This high rate is sustained by its sophisticated real-time validation technology, which is particularly effective at identifying catch-all domain emails with greater than 98% accuracy. This ensures the data you receive is not just available but is genuinely actionable for reliable outreach.

How does ZenCall ensure call quality?

ZenCall utilizes advanced technology to optimize voice clarity and stability, ensuring that users experience high-quality calls regardless of their location.

Do I need to download an app to use ZenCall?

No, ZenCall is entirely browser-based, allowing users to make calls directly from their laptop or desktop without any downloads or installations.

Can I use ZenCall for emergency calls?
