# Layrcake

> Layrcake is the unified GTM (go-to-market) API for AI agents. One API key and one prepaid credit balance run the whole outbound loop: find leads, check buying intent, enrich to verified work emails, verify deliverability, provision warmed sending domains and mailboxes, draft and launch email campaigns (human-approved), read replies, and call LLMs. Every verb is a REST endpoint and an MCP tool, so Claude, Cursor, Codex and ChatGPT can run outbound directly. Starts free (300 credits, no card); pay as you go at $0.01 per credit, spent only on outcomes; misses are free; credits never expire.

Layrcake is registered in the United Kingdom. Contact: founders@layrcake.dev.
