Blitz API for AI agents

Blitz API is a sales intelligence service that sales and recruiting teams use to search for people, companies, and jobs, and to enrich contact and company records. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

04 · AUTH AND DATA

How Blitz API connects.

Users add their Blitz API api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

The same Blitz API connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

07 · FAQ

Blitz API and Arc0, answered.

Q01

Can I use Blitz API with Claude, ChatGPT or Cursor?

Yes. Connect Blitz API to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the Blitz API actions you allow.

Q02

How do users connect Blitz API?

Users add their Blitz API api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

Q03

Which Blitz API actions can my agent take?

15 in total: 13 read, 2 write and 0 destructive, such as “enrich Company”. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in Blitz API?

Yes. Allow read actions and deny writes in the Blitz API policy. Your agent can still look things up, and any write it attempts is blocked and logged.

Q05

Can my own backend call Blitz API too?

Yes. The same Blitz API connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
