Manus

Access the Manus AI Agent API with managed API key authentication. Create and manage AI agent tasks, projects, files, and webhooks.

Quick Start

# Create a task
python <<'EOF'
import urllib.request, os, json
data = json.dumps({'prompt': 'What is the capital of France?'}).encode()
req = urllib.request.Request('https://api.maton.ai/manus/v1/tasks', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Base URL

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

Maton proxies requests to api.manus.ai 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 Manus API key connections at https://api.maton.ai.

List Connections

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

Create Connection

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

Get Connection

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

Response:

{
  "connection": {
    "connection_id": "{connection_id}",
    "status": "ACTIVE",
    "creation_time": "2026-02-28T00:12:24.030143Z",
    "last_updated_time": "2026-02-28T00:16:08.920760Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "manus",
    "metadata": {},
    "method": "API_KEY"
  }
}

Open the returned url in a browser to enter your Manus API key.

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"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Specifying Connection

If you have multiple Manus 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/manus/v1/tasks')
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 tasks, browser sessions, files, and agent executions within the connected Manus 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

// Create a task
const response = await fetch(
  'https://api.maton.ai/manus/v1/tasks',
  {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({ prompt: 'Summarize the latest news' })
  }
);
const data = await response.json();
console.log(data.task_url);

Python

import os
import requests

# Create a task
response = requests.post(
    'https://api.maton.ai/manus/v1/tasks',
    headers={
        'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}',
        'Content-Type': 'application/json'
    },
    json={'prompt': 'Summarize the latest news'}
)
task = response.json()
print(task['task_url'])

Notes

• Tasks are executed asynchronously. Use GET /manus/v1/tasks/{task_id} to poll for completion or set up a webhook
• File uploads use presigned S3 URLs that expire within 3 minutes
• Files expire after ~48 hours if not used
• Webhook payloads are signed with RSA-SHA256 for verification
• Available models: manus-1.6, manus-1.6-lite, manus-1.6-max, manus-1.5, manus-1.5-lite, speed
• Connection uses API_KEY authentication method (not OAuth)

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

Ensure your URL path starts with manus. For example:

• Correct: https://api.maton.ai/manus/v1/tasks
• Incorrect: https://api.maton.ai/v1/tasks
