name: reducto description: | Reducto document processing API integration with managed API key authentication. Parse, extract, split, and edit documents. Use this skill when users want to process documents, extract structured data, or modify PDFs and DOCX files. For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway). compatibility: Requires network access and valid Maton API key metadata: author: maton version: "1.0" clawdbot: emoji: homepage: "https://maton.ai" requires: env: - MATON_API_KEY

Reducto

Access the Reducto document processing API with managed API key authentication. Parse documents, extract structured data, split documents into sections, and edit PDFs/DOCX files.

Quick Start

# Parse a document
python <<'EOF'
import urllib.request, os, json
data = json.dumps({'document_url': 'https://example.com/document.pdf'}).encode()
req = urllib.request.Request('https://gateway.maton.ai/reducto/parse', 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/reducto/{native-api-path}

Replace {native-api-path} with the actual Reducto API endpoint path. The gateway proxies requests to platform.reducto.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 Reducto API key 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=reducto&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': 'reducto'}).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": "f7579208-276c-455f-9962-4635fca739b9",
    "status": "ACTIVE",
    "creation_time": "2026-02-28T00:12:24.797884Z",
    "last_updated_time": "2026-02-28T00:16:13.509841Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "reducto",
    "metadata": {},
    "method": "API_KEY"
  }
}

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

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 Reducto connections, specify which one to use with the Maton-Connection header:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/reducto/parse')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', 'f7579208-276c-455f-9962-4635fca739b9')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

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

Document URL Formats

2. Presigned S3 URL: https://bucket.s3.amazonaws.com/key?...
3. Reducto Upload: reducto://file-id (from /upload endpoint)
4. Previous Job: jobid://job-id (reuse parsed content from previous job)

Code Examples

JavaScript

// Parse a document
const response = await fetch(
  'https://gateway.maton.ai/reducto/parse',
  {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      document_url: 'https://example.com/document.pdf'
    })
  }
);
const data = await response.json();
console.log(data.result.chunks);

Python

import os
import requests

# Extract data from a document
response = requests.post(
    'https://gateway.maton.ai/reducto/extract',
    headers={
        'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}',
        'Content-Type': 'application/json'
    },
    json={
        'document_url': 'https://example.com/document.pdf',
        'schema': {
            'type': 'object',
            'properties': {
                'title': {'type': 'string'},
                'date': {'type': 'string'}
            }
        }
    }
)
result = response.json()
print(result['result'])

Async Job Polling

import os
import time
import requests

# Start async parse
response = requests.post(
    'https://gateway.maton.ai/reducto/parse_async',
    headers={
        'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}',
        'Content-Type': 'application/json'
    },
    json={'document_url': 'https://example.com/large-document.pdf'}
)
job_id = response.json()['job_id']

# Poll for completion
while True:
    status = requests.get(
        f'https://gateway.maton.ai/reducto/job/{job_id}',
        headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}
    ).json()

    print(f"Status: {status['status']}, Progress: {status.get('progress')}")

    if status['status'] == 'Completed':
        print(status['result'])
        break
    elif status['status'] == 'Failed':
        print(f"Failed: {status['reason']}")
        break

    time.sleep(2)

Notes

• Synchronous endpoints may timeout for large documents; use async endpoints instead
• Upload presigned URLs expire quickly; upload files immediately after calling /upload
• The reducto:// prefix URLs from /upload can be used in subsequent parse/extract/split/edit calls
• Use jobid:// prefix to reuse parsed content from a previous job (saves processing time)
• Connection uses API_KEY authentication method (not OAuth)
• Credits are consumed based on page count and operation type

Error Handling

Status	Meaning
400	Invalid request (missing required fields, invalid format)
401	Invalid or missing Maton API key
404	Resource not found
422	Validation error (check response body for details)
4xx/5xx	Passthrough error from Reducto API

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

Ensure your URL path starts with reducto. For example:

• Correct: https://gateway.maton.ai/reducto/parse
• Incorrect: https://gateway.maton.ai/parse
