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 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 credits 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, and an MCP server is available so agents can call BlitzAPI as a tool for research, enrichment, and scoring workflows.
