Layrcake

**The Unified GTM API for AI agents. The whole outbound loop, on one key.** Layrcake gives your agent one hosted MCP server and one prepaid credit balance for the entire go-to-market loop: find leads and companies, enrich people to verified work emails, verify deliverability, detect buying intent, provision warmed sending domains and mailboxes, draft and launch email campaigns, read replies, set lead status and answer threads. **How it bills.** Every tool returns the outcome and the credits it charged. A miss costs nothing. Start free with 300 credits, no card; top up from $20; credits never expire. **How it stays safe.** Free reads run without prompting. Tools that spend credits or change campaign data are annotated so your host asks first. Launching a campaign, sending a reply and buying sending capacity always need a signed-in human to approve at a link the tool returns. Suppression is re-checked before anything sends. **Tools (19).** `find_leads`, `find_companies`, `enrich`, `enrich_company`, `verify_email`, `find_intent`, `find_posts`, `setup_sending`, `create_campaign`, `add_leads`, `launch_campaign`, `get_replies`, `get_reply`, `set_lead_status`, `reply_to_thread`, `get_me`, `get_usage`, `get_operation`, `get_request`. **Connect.** OAuth 2.1 with dynamic client registration; sign in when your client prompts. Works with Claude, Cursor, ChatGPT and any Streamable HTTP client. Docs: https://docs.layrcake.dev · Pricing: https://docs.layrcake.dev/pricing.html · Privacy: https://layrcake.dev/privacy
