Frequently Asked Questions
BlitzAPI FAQ
What makes BlitzAPI different from other data providers?
Most data vendors sell you bulk, unverified lists full of outdated info. BlitzAPI flips the script. We're API-first, built to integrate into your workflow. We prioritize quality and deliverability, so you only pay for verified, accurate results (not noise). Plus, our catch-all validation is next-level.
How does the "pay for verified results" model work?
Simple. You get credits. You only use a credit when we successfully return a verified piece of data you request (like a validated email or phone). If we can't find it or verify it, you don't get charged. No more wasting money on empty searches or bad data. It's fair and scalable.
Is it easy to integrate BlitzAPI into our existing tech stack?
Absolutely. We're built by devs for modern GTM stacks. Our APIs are clean, well-documented, and designed for easy integration into CRMs (like Salesforce), marketing automation tools, data warehouses, and custom apps. You shouldn't need an engineering PhD to get it running.
What kind of data coverage and accuracy do you have?
We're packing serious heat: over 360 million verified B2B contacts and 60 million enriched company profiles. Our email deliverability rate is over 98%, thanks to real-time validation tech that even tackles catch-all domains. We focus on major markets to keep our data fresh and reliable.
