Overview

Converts a block of text into speech using a stock or previously cloned voice. This is the newest turbo tier, optimized for speed and cost. Voice settings control delivery — speaking rate, volume, pitch, and an emotional register such as calm — while audio settings control the encoding: container format, sample rate, bitrate, and mono or stereo. A language hint improves pronunciation for a particular language or dialect. Billing counts the characters submitted, so the price of a call is known before it is made.

The audio, returned inline, with its length, sample rate, size, and the character count that was billed.

Input

These go in the input object of the run request.

Example

Use your own API key and a saved idempotency key for each new job. Replace image or media placeholders with your own publicly reachable HTTPS URLs. Keep the same key and request body when recovering a timeout.

# Set once per job; reuse this key and the identical body after a timeout.
: "${AGENTSKY_IDEMPOTENCY_KEY:?Set a unique, saved key for this job}"
curl --fail-with-body https://gateway.agentsky.dev/v1/run \
  -H "authorization: Bearer $AGENTSKY_API_KEY" \
  -H "content-type: application/json" \
  -H "Idempotency-Key: $AGENTSKY_IDEMPOTENCY_KEY" \
  -d '{"provider":"minimax","endpoint":"speech-2.8-turbo","input":{"text":"Hello, and welcome back to the show.","voice_setting":{"voice_id":"female-shaonv","speed":1},"audio_setting":{"format":"mp3","sample_rate":32000}}}'
# If status is READY/RUNNING, poll GET /v1/runs/{runId} with the same API key.
