ElevenLabs

ElevenLabs

Access the ElevenLabs API with managed authentication. Generate lifelike speech from text, clone voices, create sound effects, and process audio.

Quick Start

# List available voices
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/elevenlabs/v1/voices')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Base URL

https://api.maton.ai/elevenlabs/{native-api-path}

Maton proxies requests to api.elevenlabs.io and automatically injects your API key.

Authentication

All requests require the Maton API key in the Authorization header:

Authorization: Bearer $MATON_API_KEY

Environment Variable: Set your API key as MATON_API_KEY:

export MATON_API_KEY="YOUR_API_KEY"

Getting Your API Key

1. Sign in or create an account at maton.ai
2. Go to maton.ai/settings
3. Copy your API key

Connection Management

Manage your ElevenLabs connections at https://api.maton.ai.

Delete Connection

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/connections/{connection_id}', method='DELETE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')

Specifying Connection

If you have multiple ElevenLabs connections, specify which one to use with the Maton-Connection header:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/elevenlabs/v1/voices')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', '{connection_id}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

If you have multiple connections, always include this header to ensure requests go to the intended account.

Security & Permissions

• Access is scoped to text-to-speech, voices, voice cloning, audio generation, and projects within the connected ElevenLabs account.
• All write operations require explicit user approval. Before executing any create, update, or delete call, confirm the target resource and intended effect with the user.

Code Examples

JavaScript - Text to Speech

const response = await fetch(
  'https://api.maton.ai/elevenlabs/v1/text-to-speech/JBFqnCBsd6RMkjVDRZzb',
  {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      text: 'Hello world!',
      model_id: 'eleven_multilingual_v2'
    })
  }
);
const audioBuffer = await response.arrayBuffer();

Python - Text to Speech

import os
import requests

response = requests.post(
    'https://api.maton.ai/elevenlabs/v1/text-to-speech/JBFqnCBsd6RMkjVDRZzb',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'},
    json={
        'text': 'Hello world!',
        'model_id': 'eleven_multilingual_v2'
    }
)
audio_data = response.content
with open('output.mp3', 'wb') as f:
    f.write(audio_data)

Python - List Voices

import os
import requests

response = requests.get(
    'https://api.maton.ai/elevenlabs/v1/voices',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}
)
voices = response.json()
for voice in voices['voices']:
    print(f"{voice['name']}: {voice['voice_id']}")

Notes

• Text-to-Speech is billed per character
• Sound Effects are billed per generation
• Speech-to-Text is billed per audio minute
• Audio output format can be specified as codec_sample_rate_bitrate (e.g., mp3_44100_128)
• Models available: eleven_multilingual_v2 (recommended), eleven_turbo_v2_5 (low latency)
• Voice IDs can be found using the List Voices endpoint
• Maximum text length varies by model
• IMPORTANT: When using curl commands, use curl -g when URLs contain brackets to disable glob parsing
• IMPORTANT: When piping curl output to jq, environment variables may not expand correctly. Use Python examples instead.

Error Handling

Troubleshooting: API Key Issues

1. Check that the MATON_API_KEY environment variable is set:

echo $MATON_API_KEY

1. Verify the API key is valid by listing connections:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/connections')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Troubleshooting: Invalid App Name

1. Ensure your URL path starts with elevenlabs. For example:

• Correct: https://api.maton.ai/elevenlabs/v1/voices
• Incorrect: https://api.maton.ai/v1/voices
