Deploy a Python Flask App with OpenClaw

This guide shows how to deploy a Python Flask app with OpenClaw. Flask's simplicity makes it excellent for AI backends.

The Flask App

# app.py
from flask import Flask, jsonify, request
import os

app = Flask(__name__)

@app.get('/health')
def health():
    return jsonify({'status': 'ok'})

@app.post('/chat')
def chat():
    data = request.get_json()
    message = data.get('message')
    # OpenClaw handles AI routing
    response = openclaw.chat(message)
    return jsonify({'response': response})

if __name__ == '__main__':
    app.run(host='0.0.0.0', port=int(os.getenv('PORT', 3000)))
