Fish Audio

Fish Audio — Text-to-Speech

Generate narration / voiceover through AceDataCloud's Fish Audio API.

Setup: See authentication for token setup.

Quick Start

curl -X POST https://api.acedata.cloud/fish/tts \
  -H "Authorization: ******ACEDATACLOUD_API_TOKEN" \
  -H "Content-Type: application/json" \
  -H "model: s2-pro" \
  -d '{"text":"你好，欢迎使用 AceData Cloud。","reference_id":"d7900c21663f485ab63ebdb7e5905036","format":"mp3"}'

Synchronous responses return a direct audio URL:

{"audio_url":"https://platform.r2.fish.audio/task/8a72ff9840234006a9f74cb2fa04f978.mp3"}

Endpoints

Workflows

1. Find a reference voice

curl "https://api.acedata.cloud/fish/model?page_size=10&page_number=1&title=Marcus" \
  -H "Authorization: ******ACEDATACLOUD_API_TOKEN"

The response includes items[] with public voice metadata such as _id, title, languages, tags, visibility, and state. Use an item _id as reference_id in TTS requests.

2. Text-to-Speech

POST /fish/tts
Headers:
  model: s2-pro

{
  "text": "Your narration text.",
  "reference_id": "d7900c21663f485ab63ebdb7e5905036",
  "format": "mp3"
}

3. Async TTS

POST /fish/tts
Headers:
  model: s1

{
  "text": "Longer narration for background processing.",
  "async": true,
  "callback_url": "https://api.acedata.cloud/health"
}

Async: See async task polling. Poll via POST /fish/tasks with {"id":"..."}.

Parameters — /fish/tts

JSON body

Gotchas

• The documented TTS endpoint is POST /fish/tts — not /fish/audios.
• Choose the Fish engine with the model request header, not a JSON model field.
• Use reference_id from GET /fish/model — not voice_id.
• Synchronous requests return audio_url directly; async jobs should be polled via /fish/tasks.
