Developer-first platform

Everything the UI can do, the API can do.

Full REST API. MCP server. Zero locked features.

API highlights.

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

Full CRUD on all resources

Contacts, campaigns, posts, funnels, referrals, affiliates. Every object is an API resource.

Scoped API keys

Read, write, admin. Issue keys per integration, revoke individually. SHA-256 hashed at rest.

Webhook subscriptions

Subscribe to any event: contact.created, campaign.sent, referral.converted. Real-time delivery.

Event-driven architecture

Every action emits an event. Build reactive workflows, audit trails, and real-time dashboards.

Nobody in this space has this

Claude, GPT, Cursor — connect via MCP. Spin up campaigns, build funnels, manage contacts without touching the dashboard.

Standard MCP protocol — works with any compatible client

Full tool coverage: contacts, campaigns, posts, funnels

Scoped permissions — give agents exactly the access they need

Event streaming for real-time agent reactions
