Layrcake is one key your agent uses to find people, verify and enrich them, send from warmed inboxes and read the replies, from Claude, ChatGPT, Cursor or any MCP client. Here is how that compares with the two kinds of tool it replaces.

No. Finding, enriching and verifying run on their own. Launching a campaign, replying to a thread and buying sending capacity wait for your approval, every time. If you want an agent to act unattended, you switch that on per key, and only for that key.
About 60 verified work emails, or 50 company matches, or 300 verifications. A credit is one cent. Misses cost nothing, so you only pay for people who exist.
No. Ask for sending capacity and warmed domains and mailboxes are provisioned for you: 1,500 credits per domain once, 750 credits per mailbox per month, quoted before anything is bought.
From a waterfall of specialist data providers, routed per request and verified before you see a result. Layrcake is a UK company; the data processing addendum is at layrcake.dev/dpa and suppression is enforced before every send.
You sign in, no card, and the key is on screen. Paste the connect block for your tool, type one of the prompts on this page, and the first result is back inside two minutes.
Every account begins with 300 free credits — no card, full API, every verb. Top up as you go: 1 credit = $0.01, spent only on outcomes. Credits never expire.
