Frequently Asked Questions
BlitzAPI FAQ
What makes BlitzAPI different from other data providers?
BlitzAPI is built as an API-first infrastructure, not just a data portal!

You only pay for verified, successful results, not for credits wasted on bad data. Our APIs are designed for seamless integration, fitting into your existing workflow without forcing you to adapt to a rigid tool.

Our "Waterfall ICP" feature is designed for efficiency! You define your ideal customer persona, and our algorithm prioritizes leads that match it. The system will search and return the best matches first. More importantly, you only use credits for successfully enriched and verified data.

Absolutely! We encourage you to experience the power of clean data firsthand. You can get started with 1,000 free credits to test our APIs—no credit card required. This allows you to run searches, enrich contacts, and validate emails to see the quality and speed for yourself.

What kind of integrations does BlitzAPI support?
BlitzAPI is built for developers and no-code users alike! We offer a clean, well-documented REST API that can integrate with any modern tech stack, including CRMs (like Salesforce, HubSpot), sales engagement platforms, marketing automation tools, and custom internal systems. The API-first architecture means you can connect it anywhere you need clean B2B data to flow, enabling truly automated workflows.
Vendor Space FAQ
How quickly can I set up my first event?
Incredibly fast! Most organizers have their first event live and ready to accept vendors within 15 minutes. Simply create your event, configure your booth options and pricing, and instantly share your unique vendor registration page. It's designed for speed so you can focus on what matters most--curating an amazing event!
What does the 6% transaction fee cover?
The 6% fee is a flat rate applied only when you successfully collect a payment from a vendor or sponsor. This single fee covers all payment processing (powered by Stripe), access to the entire Vendor Space platform, unlimited events, and all features including the vendor portal, booth mapping, contracts, and analytics. There are no monthly subscriptions or hidden costs ever!
Can I manage sponsors alongside vendors?
Absolutely! Sponsor management is a core module built directly into Vendor Space. You can create custom sponsorship tiers with specific benefits, track deliverables, and manage all communication and payments for your sponsors right from the same dashboard you use for vendors. This integration ensures a cohesive and professional partnership experience.
Do vendors need an account to apply and pay?
No, it's super easy for them! Vendors do not need to create a separate Vendor Space account. They simply click on the unique registration link you provide, fill out your custom application form, and can complete payment securely via credit card. They receive a portal to manage their info, but the barrier to entry is beautifully low, encouraging more applications.
