Capabilities
One interface.
Clear boundaries.
Designed as composable infrastructure, with Preview labels wherever production behavior is not yet available.
01
HTTP synthesis
Documented, observable and designed to fit into your existing product architecture.
02
SSE streaming
Documented, observable and designed to fit into your existing product architecture.
03
Voice selection
Documented, observable and designed to fit into your existing product architecture.
04

Interface example
Start with a request.
Inspect every field.
Use a project API key from your server and follow the capability status documented on this page.
curl https://api.audelyr.ai/v1/speech/synthesize \
-H "Authorization: Bearer $AUDELYR_API_KEY" \
-H "Idempotency-Key: tts-demo-001" \
-H "Content-Type: application/json" \
-d '{"text":"Hello from Audelyr","voice":"nova","audio_format":"mp3"}'02
Before you begin
Create a project API key in the console and keep it on your server.
03
Request lifecycle
Realtime connections return events as audio is processed. HTTP and SSE endpoints return structured errors when a request cannot run.
04
Availability
Each guide states whether its capability is available today or still planned. Do not send production traffic to an endpoint marked unavailable.
Early Access
Build the interface
before the infrastructure.
Explore the honest Preview, then tell us what production voice needs from Audelyr.
