About this skill
API Gateway
Passthrough proxy for direct access to third-party APIs using managed OAuth connections, provided by Maton. The API gateway lets you call native API endpoints directly.
Quick Start
# Native Slack API call
python <<'EOF'
import urllib.request, os, json
data = json.dumps({'channel': 'C0123456', 'text': 'Hello from gateway!'}).encode()
req = urllib.request.Request('https://gateway.maton.ai/slack/api/chat.postMessage', 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/{app}/{native-api-path}
Replace {app} with the service name and {native-api-path} with the actual API endpoint path.
IMPORTANT: The URL path MUST start with the connection's app name (eg. /google-mail/...). This prefix tells the gateway which app connection to use. For example, the native Gmail API path starts with gmail/v1/, so full paths look like /google-mail/gmail/v1/users/me/messages.
Authentication
All requests require the Maton API key in the Authorization header:
Authorization: Bearer $MATON_API_KEY
The API gateway automatically injects the appropriate OAuth token for the target service.
Environment Variable: You can set your API key as the MATON_API_KEY environment variable:
export MATON_API_KEY="YOUR_API_KEY"
Getting Your API Key
- Sign in or create an account at maton.ai
- Go to maton.ai/settings
- Click the copy button on the right side of API Key section to copy it
Connection Management
Connection management uses a separate base URL: https://ctrl.maton.ai
List Connections
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections?app=slack&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
Query Parameters (optional):
app- Filter by service name (e.g.,slack,hubspot,salesforce)status- Filter by connection status (ACTIVE,PENDING,FAILED)
Response:
{
"connections": [
{
"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=5e9...",
"app": "slack",
"method": "OAUTH2",
"metadata": {}
}
]
}
Create Connection
python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'slack'}).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
Request Body:
app(required) - Service name (e.g.,slack,notion)method(optional) - Connection method (API_KEY,BASIC,OAUTH1,OAUTH2,MCP)
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=5e9...",
"app": "slack",
"metadata": {}
}
}
Open the returned URL in a browser to complete OAuth.
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 connections for the same app, you can specify which connection to use by adding the Maton-Connection header with the connection ID:
python <<'EOF'
import urllib.request, os, json
data = json.dumps({'channel': 'C0123456', 'text': 'Hello!'}).encode()
req = urllib.request.Request('https://gateway.maton.ai/slack/api/chat.postMessage', 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 for that app.

Also use when user references an existing image file and asks to modify it in any way (e.g., "modify this image", "change the background", "replace X with Y"). Supports both text-to-image generation and image-to-image editing with configurable resolution (1K default, 2K, or 4K for high resolution). DO NOT read the image file first - use this skill directly with the --input-image parameter.
