Kai can send calls and leads where your business already works.
The public product promise is simple: no app to learn, no dashboard to babysit. The developer promise is what makes that possible behind the scenes: scoped API access, signed webhooks, outbound actions, and integrations that move work into the systems your business already runs on.
Scoped access
Issue scoped API keys, limit them to a business when needed, and keep dashboard-authenticated key management separate from public API calls.
Signed event delivery
Use signed webhooks for `lead.created`, `lead.scored`, and `call.completed` so downstream systems can verify source before acting.
Move work, not just data
Route calls, trigger follow-up, send SMS, and sync outcomes into the calendar, CRM, webhook, or tool chain your business already uses.
Start with the right surface
Use the plain-language page to understand why the platform exists. Use the full docs when you are ready to wire the mechanics.
Authentication and permissioning
Bearer auth, OAuth surfaces, scoped keys, business-level access, and one-time secret display for new credentials.
Agents, calls, and follow-up actions
Create or update agents, place outbound calls, send SMS, and keep follow-up behavior tied to the same business context.
Leads, transcripts, and event flows
Push lead outcomes into your system of record and react to call events without forcing owners into a separate operator app.
Messaging and webhook operations
SMS and webhook tooling are documented alongside the event model so follow-up systems stay connected to the call lifecycle.
Quick start
A common first use case is pushing an outbound follow-up call from your own workflow instead of asking staff to swivel between tools.
