Embed speech generation, voice workflows, and usage controls directly into your own product stack.
API Access
Production voice capabilities ready to connect with the products you already build.
Authentication, voice endpoints, and observable events give developers a predictable path from the first request to production traffic.
Request lifecycle
Scoped authentication, stable endpoints, and visible events create a dependable runtime from integration through production.
System
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.
System
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.
System
Separate environments and observe usage
Scope credentials, protect server-side secrets, handle errors, and monitor request volume as the integration moves into production.
Create scoped credentials, make the first request, handle events and failures, then monitor the complete integration in production.
Use a server-side key for the appropriate test or production environment.
Call the required agent, call, or speech endpoint from your backend.
Verify webhook requests and process state changes idempotently.
Track latency, failures, limits, and usage as traffic grows.
Connect API events to the rest of your application stack.
Create agents, initiate calls, generate speech, and retrieve outcomes using focused endpoints that fit an existing backend or application.
Included controls
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.
Verify the request signature, acknowledge events quickly, queue slower work, and process event identifiers idempotently so retries do not create duplicate actions.
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.
Track request errors, call outcomes, webhook delivery, end-to-end latency, usage, and any downstream system failures that affect the customer experience.
