Talk to it like you would talk to Claude

A real conversation. Everything below works the same in the search bar, from the REST API, or from inside your own agent.

AgentData · 128 million companies · free forever

Hi. I know 128 million companies: their tech stacks, email patterns, people, and what changed on their websites this week. Ask me about one, or tell me who you are looking for.

What do you know about fathom.co?

Nothing yet, so I have gone to get it. Fathom is at the front of the crawl queue.

Find SaaS companies using Intercom that I could email

6,076 companies use Intercom. Here are five in Software & SaaS with contacts, sorted by how complete the profile is:

The same question as an API call, no key needed:
GET /api/v1/companies?tech=Intercom&sector=Software%20%26%20SaaS

Company, tech and signal data is open. Emails and people need a free account: 1,000 reveals a day, no card.

Can my agent do this itself?

Yes. I speak MCP, so anything that runs tools can call me with one line of config. Six tools: lookup, companies, people, tech, signals and usage.

Anything with an HTTP step can use the REST API instead. Docs →

What does it cost?

Nothing. Search, company pages, tech stacks and signals are free without an account. A free account adds 1,000 contact reveals a day, 5,000 API requests every 5 hours, and one bucket across the website, the API and MCP. No card, no trial, no credits.

If you ever hit those numbers, Pro is $99 a year for 10x the contacts and 5x the requests.

A company you have revealed stays open for 30 days without using another reveal. Why it is free →

Works wherever your agent lives

MCP for anything that runs tools. REST for anything with an HTTP step.
