Composable primitives
Build around the voice capabilities you need
Create agents, initiate calls, generate speech, and retrieve outcomes using focused endpoints that fit an existing backend or application.

Observability
From key to production
A developer path that stays clear as usage grows.
Create scoped credentials, make the first request, handle events and failures, then monitor the complete integration in production.
- 01
Create credentials
Use a server-side key for the appropriate test or production environment.
- 02
Make a request
Call the required agent, call, or speech endpoint from your backend.
- 03
Handle events
Verify webhook requests and process state changes idempotently.
- 04
Monitor and scale
Track latency, failures, limits, and usage as traffic grows.
Inside a production request
Clear primitives at the edge. Strong controls underneath.
Authentication, voice endpoints, and observable events give developers a predictable path from the first request to production traffic.
Event-driven workflows
Respond when the conversation changes state
Use signed webhook events to connect call starts, completions, transfers, and outcomes to the rest of your product workflow.
Production controls
Separate environments and observe usage
Scope credentials, protect server-side secrets, handle errors, and monitor request volume as the integration moves into production.

Frequently asked questions
What developers ask before integration.
A practical overview of api access, setup, and how your team stays in control.
Where should API keys be stored?
Keep API keys in a server-side secret store and never expose them in browser or mobile client code. Use separate credentials and least-privilege access for each environment.
How should webhook events be processed?
Verify the request signature, acknowledge events quickly, queue slower work, and process event identifiers idempotently so retries do not create duplicate actions.
Can we test before making live calls?
Use a separate development environment, test data, and approved destination numbers where available. Validate the complete event and error path before enabling a production workflow.
What should we monitor in production?
Track request errors, call outcomes, webhook delivery, end-to-end latency, usage, and any downstream system failures that affect the customer experience.
