OATDA Audio Translation

Translate foreign-language audio into English text through OATDA's unified audio API.

API Key Resolution

All commands need the OATDA API key. Resolve it inline for each exec call:

export OATDA_API_KEY="${OATDA_API_KEY:-$(cat ~/.oatda/credentials.json 2>/dev/null | jq -r '.profiles[.defaultProfile].apiKey' 2>/dev/null)}"

If the key is empty or null, tell the user to get one at https://oatda.com and configure it.

Security: Never print the full API key. Only verify existence or show first 8 chars.

Model Mapping

User says	Provider	Model
whisper, whisper-1, openai whisper (default)	openai	whisper-1
translate audio, audio translation	openai	whisper-1

Default: openai / whisper-1 if no model specified.

If the user provides provider/model format directly (for example openai/whisper-1), split on /.

⚠️ Models change over time. If a model ID fails, query oatda-list-models with ?type=audio first.

Input Preparation

The translation endpoint supports:

• multipart/form-data with a local file upload
• JSON with a base64 data URL in file

Maximum audio file size is 25MB.

For local files, prefer multipart upload because it is simpler and avoids large JSON bodies.

Discovering Audio Model Parameters

export OATDA_API_KEY="${OATDA_API_KEY:-$(cat ~/.oatda/credentials.json 2>/dev/null | jq -r '.profiles[.defaultProfile].apiKey' 2>/dev/null)}" && \
curl -s -X GET "https://oatda.com/api/v1/llm/models?type=audio" \
  -H "Authorization: Bearer $OATDA_API_KEY" | jq '.audio_models[] | {id, supported_params}'

Look for:

• audio_modes containing translation
• supported response_format values
• optional prompt or filename support

API Call (multipart)

export OATDA_API_KEY="${OATDA_API_KEY:-$(cat ~/.oatda/credentials.json 2>/dev/null | jq -r '.profiles[.defaultProfile].apiKey' 2>/dev/null)}" && \
curl -s -X POST "https://oatda.com/api/v1/llm/translations" \
  -H "Authorization: Bearer $OATDA_API_KEY" \
  -F "provider=<PROVIDER>" \
  -F "model=<MODEL>" \
  -F "file=@<AUDIO_FILE>" \
  -F "response_format=json"

Alternative API Call (base64 JSON)

AUDIO_DATA_URL="data:audio/mpeg;base64,$(base64 -w 0 audio.mp3)"

export OATDA_API_KEY="${OATDA_API_KEY:-$(cat ~/.oatda/credentials.json 2>/dev/null | jq -r '.profiles[.defaultProfile].apiKey' 2>/dev/null)}" && \
curl -s -X POST "https://oatda.com/api/v1/llm/translations" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $OATDA_API_KEY" \
  -d "$(jq -n \
    --arg provider \"<PROVIDER>\" \
    --arg model \"<MODEL>\" \
    --arg file \"$AUDIO_DATA_URL\" \
    '{provider: $provider, model: $model, file: $file, response_format: \"json\"}')"

Common Parameters

• prompt: Optional hint for terminology, names, or translation style
• response_format: json, text, srt, verbose_json, or vtt
• temperature: 0 to 1
• filename: Optional filename for JSON uploads

Response Format

The API returns JSON like:

{
  "text": "The English translation...",
  "language": "fr",
  "duration": 42.5,
  "costs": {
    "inputCost": 0,
    "outputCost": 0.0001,
    "totalCost": 0.0001,
    "currency": "USD"
  }
}

Present the text field to the user and mention that the output is English.

Error Handling

HTTP Status	Meaning	Action
401	Invalid API key	Tell user to check their key
402	Insufficient credits	Tell user to check balance
400	Bad request / model not supported	Check model or file format and query oatda-list-models with type=audio
413	File too large	Keep audio under 25MB or split it
429	Rate limited or monthly cap	Wait briefly and retry once

Example

export OATDA_API_KEY="${OATDA_API_KEY:-$(cat ~/.oatda/credentials.json 2>/dev/null | jq -r '.profiles[.defaultProfile].apiKey' 2>/dev/null)}" && \
curl -s -X POST "https://oatda.com/api/v1/llm/translations" \
  -H "Authorization: Bearer $OATDA_API_KEY" \
  -F "provider=openai" \
  -F "model=whisper-1" \
  -F "file=@french-audio.mp3" \
  -F "response_format=json"
