Developer-first platform

The public API is included on every plan, including free.

API highlights.

Not an afterthought. The API is how we built the product.

Scoped API keys

Per-pillar scopes — contacts, campaigns, blog, funnels, and more. Issue keys per integration, revoke individually. SHA-256 hashed at rest.

Webhook subscriptions

Webhooks are signed and logged. Subscribe to page.published and contact.captured, or to contact.suppressed through the API.

Nobody in this space has this

AI agents operate GrowthFox natively.

Claude, GPT, Cursor — point any agent at the API. Spin up campaigns, build funnels, manage contacts without touching the dashboard. (MCP server on the roadmap.)

Scoped keys — give agents exactly the access they need

Simple, predictable API.

RESTful. JSON. Bearer token auth. No surprises.
