Contract-first REST for builders and agents. Same control plane as Fat Heron products — documented here for the developer surface.
Imperative playbooks for VS Code, Claude, Cursor, and other agents. Prefer these over UI click-ops. Auth with X-API-Key against https://api.fatheron.dev. Full contract: openapi.json · Swagger. Machine index: /llms.txt. New? Human guides (less technical) or Get started.
Goal-first onboarding for email, Domainers, and research with an AI assistant — no API tour required.
Domainers and builders: mint a key, connect VS Code / Claude / Cursor, run a first recipe.
Preferred client — servers + secure inputs, Copilot instructions, verify checklist.
Official @fat-heron/mcp stdio server — projects, aliases, DNS, billing, webhooks, sandbox via API key.
Shell + TypeScript client for the same /v1 recipes, including fh apply.
Open a workspace for a product, consultancy, or freelance practice.

Receive account events at a public HTTPS URL (SSRF-guarded).
Scopes: notifications:write
Create a mailbox alias on a domain already available to the account.
Scopes: aliases:write
Metered comps, research cards, drops, and acquire preview over Fat Heron’s owned domain graph. Not a Domainers LLM — your agent calls these tools.
