What makes BlitzAPI different from other B2B data providers?

BlitzAPI is distinguished by its unwavering commitment to data quality and a true API-first, deliverability-focused architecture. Unlike providers that sell bulk, unverified lists, we prioritize accuracy over volume, with features like real-time catch-all validation ensuring over 98% email deliverability. Our pricing model charges only for verified results, not attempts, aligning our success directly with yours. Furthermore, our APIs are designed for flexible integration, adapting to your workflow rather than forcing you into a rigid platform.

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

Our credit system is consumption-based and results-driven. You are charged a credit only when our API successfully returns a verified piece of data you request, such as a validated email or an enriched phone number. If we cannot find or verify the requested information, no credit is consumed. This model ensures you never pay for bad data, directly tying your cost to the value received and providing transparent, predictable ROI on your data investment.

Can BlitzAPI integrate with our existing tech stack (CRM, MAP, etc.)?

Absolutely. BlitzAPI is built as a flexible, developer-friendly API specifically for seamless integration into existing ecosystems. It can be integrated directly into popular CRM platforms like Salesforce and HubSpot, marketing automation platforms, data warehouses, and custom internal tools via REST API. This allows you to automate data enrichment and validation within your current workflows without disruptive platform changes or manual processes.

What is your data coverage and accuracy rate?

Our database covers over 360 million verified B2B contacts and 60 million enriched company profiles across major global markets. We maintain a high accuracy standard, with an email deliverability rate exceeding 98%, thanks to our multi-layered validation process and proprietary catch-all detection. Data is continuously updated and verified to ensure freshness, providing teams with reliable information for their critical GTM activities.
