When they open a company, list its people by role, seniority and department, page by page.

Frequently asked questions
How do I integrate BlitzAPI into my application?
Every capability is a standard REST endpoint returning structured JSON. Typed SDKs are available for Python and TypeScript / JavaScript, so you can call search, enrichment, and validation from your backend, internal tools, or agents.
Can I try the API before committing?
Yes. Sign up and you get 1,000 free records to test endpoints against real data, enough to prototype a feature end to end before wiring it into production.
What happens when a record can't be found?
You get an explicit not-found response instead of a guessed value. BlitzAPI favors verification over guesswork, which keeps the data you ship into your product clean and predictable.
Can AI agents use BlitzAPI?
Yes. The structured JSON outputs are designed to be consumed programmatically: an agent can call the REST API or the typed SDKs as tools for research, enrichment and scoring. The MCP server gives AI tools like Claude and Cursor one tool per endpoint, plus the docs, and Blitz Skills package ready-to-run GTM playbooks for coding agents.
