Free go-to-market tools

Three checks you'd otherwise pay a tool for. Each runs the same call your AI agent makes with a Layrcake key. 3 free tries a day each, no account.

Check if an email address will deliver

Paste a work email. We ask the mail server whether the mailbox exists, without sending anything, and tell you whether it's safe to send to.

Find a company's email format

Enter a company's domain. We read addresses at that company that have passed a mailbox check and show the format they follow. We never guess a person's address.

See who engaged with a post

Paste a public LinkedIn or X post. See how many people engaged, how, and what they do for a living. Names come with a free account.

Your next move

Give your AI agent the key to go to market.

The right companies, people, details and signals, all available through one API key. Ready for your AI agent the moment you paste it. Nothing sends until you say so. Free to start, then pay as you go.
