Developers & Automation
Use the Creative REST API and MCP to generate ads from your own apps and agents.
Everyday creative work happens in the brand workspace. Use this section when you want AdGreetz to run from another system.
API
The versioned Creative REST API uses the same generation pipelines as the app. Authenticate with a bearer API key from Settings → API Keys, or a Supabase OAuth access token.
See the API overview and the interactive reference.
MCP
The Model Context Protocol endpoint lets Claude, Cursor, Codex, and other agents generate ads on a team you authorize.
How this relates to brands
API and MCP generations still resolve to a brand. Pass an existing brand_id, or a brand name plus website, the same way the app creates or reuses a brand. Website query strings are stripped when the brand is stored.
If you are setting up the brand in the UI first, start with Create a brand.
