FAQ

About this tool

What can it not see?

Tools that leave no trace on the public site: a CRM used only by the team, a data warehouse, an internal billing system. What it sees is reliable; what it misses is the back office.

Can I look up a list of domains?

From your agent, with batch_run: the prompt under the result does it and keeps the accounts that use the tools you sell into or replace.

Is it really free?

Yes, with a daily allowance per network so the tool stays open for everybody. No sign-up, no email. The same input inside 7 days is answered from the stored result. Past the allowance, the same calls run from your own agent with a key, priced per call.
