Frequently asked questions

How do I start building with BlitzAPI?

Create an account and you get 1,000 free credits to test real workflows, no sales call required. Every endpoint is standard REST with structured JSON outputs, so you can run your first search or enrichment call in minutes.

Does BlitzAPI work with Clay, n8n, and custom agents?

Yes. BlitzAPI is the API layer behind Clay workflows, n8n and Make automations, CRMs, internal tools, and custom agents. Any system that can send an HTTP request can call the endpoints and route the structured outputs, for your own use. Redistributing the data or your API access through a marketplace or a third-party listing is outside what our Terms allow.

How fresh is the data behind these workflows?

Records are refreshed continuously through captured signals and recurring update cycles, and verified emails are re-tested against mail infrastructure at least every 30 days, so recurring workflows keep running on current data.

What kind of data does BlitzAPI provide?

BlitzAPI focuses on business-context B2B data: companies, professional profiles, work emails, and job postings. See our privacy policy for how data is processed, and contact us if your team has specific compliance requirements.
