What is BlitzAPI?

BlitzAPI is an API-first B2B data platform that delivers fresh, verified contact and company information directly into your workflows. Instead of burning credits on stale leads or guessing at email accuracy, BlitzAPI provides search, enrichment, and validation tools designed to power modern go-to-market (GTM) playbooks. With over 360 million verified B2B contacts and 60 million enriched company profiles, it acts as the infrastructure layer for growth and revenue teams that need reliable data at scale.

Who it's for

• Growth teams that want to automate lead generation and enrichment without juggling multiple data vendors.
• Revenue operations that need clean, validated contact data to improve email deliverability and reduce bounce rates.
• GTM engineers building scalable outreach sequences who require a programmable API with predictable pricing and high throughput.

Key features

Smart ICP Targeting

BlitzAPI’s algorithm identifies and ranks your ideal decision-makers instantly. You define your ideal customer profile, and the API returns only the most relevant contacts, prioritized by fit. This eliminates manual filtering and ensures your outreach lands on the right people.

Verified Email & Phone Enrichment

Get accurate, verified email addresses and direct phone numbers for your target contacts. The enrichment engine cross-references multiple sources to deliver data you can trust, reducing the time spent on manual research and verification.

Catch-All Email Validation

Validate catch-all email domains in real time with over 98% accuracy. Instead of guessing whether an email will bounce, BlitzAPI confirms deliverability before you send, helping you maintain sender reputation and campaign performance.

Real-Time LinkedIn Scraping API

Enrich company and profile data from LinkedIn through a reliable, real-time API. This feature lets you pull up-to-date professional information without building or maintaining your own scraping infrastructure.

What stands out

"BlitzAPI is not just another data provider. It’s the infrastructure behind thousands of GTM workflows."

The platform is built around an API-first philosophy, meaning every feature — from enrichment to validation — is accessible through simple API calls. This makes it easy to integrate into existing stacks without custom middleware. The pricing model is also notable: you pay only for verified results, with no hidden fees or lock-in. Plans start at $49 for unlimited email validation and $399 for unlimited leads and companies, making it a cost-effective alternative to per-credit data providers.
