PDF.co

Access the PDF.co API with managed authentication. Convert, merge, split, and edit PDFs with full document manipulation capabilities.

Quick Start

# Get PDF info
python <<'EOF'
import urllib.request, os, json
data = json.dumps({'url': 'https://example.com/sample.pdf'}).encode()
req = urllib.request.Request('https://gateway.maton.ai/pdf-co/v1/pdf/info', 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://gateway.maton.ai/pdf-co/{native-api-path}

Replace {native-api-path} with the actual PDF.co API endpoint path. The gateway proxies requests to api.pdf.co and automatically injects your API credentials.

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 PDF.co connections at https://ctrl.maton.ai.

List Connections

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections?app=pdf-co&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': 'pdf-co'}).encode()
req = urllib.request.Request('https://ctrl.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://ctrl.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": "21fd90f9-5935-43cd-b6c8-bde9d915ca80",
    "status": "ACTIVE",
    "creation_time": "2025-12-08T07:20:53.488460Z",
    "last_updated_time": "2026-01-31T20:03:32.593153Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "pdf-co",
    "metadata": {}
  }
}

Open the returned url in a browser to complete authorization.

Delete Connection

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.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 PDF.co connections, specify which one to use with the Maton-Connection header:

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'url': 'https://example.com/sample.pdf'}).encode()
req = urllib.request.Request('https://gateway.maton.ai/pdf-co/v1/pdf/info', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
req.add_header('Maton-Connection', '21fd90f9-5935-43cd-b6c8-bde9d915ca80')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

If omitted, the gateway uses the default (oldest) active connection.

Code Examples

JavaScript

const response = await fetch(
  'https://gateway.maton.ai/pdf-co/v1/pdf/merge',
  {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      url: 'https://example.com/doc1.pdf,https://example.com/doc2.pdf',
      name: 'merged.pdf'
    })
  }
);
const result = await response.json();
console.log(result.url);

Python

import os
import requests

response = requests.post(
    'https://gateway.maton.ai/pdf-co/v1/pdf/merge',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'},
    json={
        'url': 'https://example.com/doc1.pdf,https://example.com/doc2.pdf',
        'name': 'merged.pdf'
    }
)
result = response.json()
print(result['url'])

Notes

• All file URLs must be publicly accessible or use PDF.co temporary storage
• Multiple URLs for merge operations should be comma-separated
• Page indices are 0-based (first page is 0)
• Page ranges use format: 0-2 (pages 0,1,2), 3- (page 3 to end), 0,2,4 (specific pages)
• Output files are stored temporarily and expire after 60 minutes by default
• Use async: true for large files to avoid timeout
• Use inline: true to get content directly in response instead of URL
• IMPORTANT: When using curl commands, use curl -g when URLs contain brackets to disable glob parsing
• IMPORTANT: When piping curl output to jq or other commands, environment variables like $MATON_API_KEY may not expand correctly in some shell environments

Error Handling

Troubleshooting: API Key Issues

1. Check that the MATON_API_KEY environment variable is set:

echo $MATON_API_KEY

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

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.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 pdf-co. For example:

• Correct: https://gateway.maton.ai/pdf-co/v1/pdf/merge
• Incorrect: https://gateway.maton.ai/v1/pdf/merge
