Usage Examples

Code examples and common use cases for the Devin API

Quick Examples

Creating and Monitoring Sessions

import os
import requests
import time

DEVIN_API_KEY = os.getenv("DEVIN_API_KEY")

# Create a new session
response = requests.post(
    "https://api.devin.ai/v1/sessions",
    headers={"Authorization": f"Bearer {DEVIN_API_KEY}"},
    json={
        "prompt": "Review PR #249",
        "idempotent": True
    }
)

print("Response:\n"+ str(response.json()))
session_id = response.json()["session_id"]

# Monitor session status
while True:
    status = requests.get(
        f"https://api.devin.ai/v1/session/{session_id}",
        headers={"Authorization": f"Bearer {DEVIN_API_KEY}"}
    ).json()
    print("Status:\n" + str(status))
    if status["status_enum"] in ["blocked", "stopped"]:
        break
    time.sleep(5)

File Upload and Processing

import os
import requests

DEVIN_API_KEY = os.getenv("DEVIN_API_KEY")

# Upload a file
with open("data.csv", "rb") as f:
    response = requests.post(
        "https://api.devin.ai/v1/attachments",
        headers={"Authorization": f"Bearer {DEVIN_API_KEY}"},
        files={"file": f}
    )
file_url = response.text

# Create a session to process the file
response = requests.post(
    "https://api.devin.ai/v1/sessions",
    headers={"Authorization": f"Bearer {DEVIN_API_KEY}"},
    json={
        "prompt": f"Analyze the data in {file_url}"
    }
)

print(str(response.json()))

Interactive Sessions

import os
import requests

DEVIN_API_KEY = os.getenv("DEVIN_API_KEY")

# Send a message to an active session
requests.post(
    f"https://api.devin.ai/v1/session/{session_id}/message",
    headers={"Authorization": f"Bearer {DEVIN_API_KEY}"},
    json={
        "message": "Make sure to write units tests when you are done."
    }
)

GitHub Repository Analysis

Here’s a complete example that demonstrates how to use the Devin API to analyze GitHub repositories. This example shows:

• Authentication and error handling
• Creating and monitoring sessions
• Processing structured output
• Proper resource management with async/await

import os
import aiohttp
import asyncio
from typing import List, Dict

API_KEY = os.getenv("DEVIN_API_KEY")
API_BASE = "https://api.devin.ai/v1"

async def count_stars(session: aiohttp.ClientSession, repo_url: str) -> int:
    """Count stars for a GitHub repository using Devin."""
    # Create a new Devin session
    async with session.post(
        f"{API_BASE}/sessions",
        json={"prompt": f"Count stars for GitHub repository: {repo_url}"}
    ) as response:
        session_data = await response.json()
        session_id = session_data["session_id"]
        print(f"Created session {session_id} for {repo_url}")
        print(f"URL: {session_data['url']}")

    # Poll for results with exponential backoff
    backoff = 1
    print("Polling for results...")
    while True:
        async with session.get(
            f"{API_BASE}/session/{session_id}"
        ) as response:
            response_json = await response.json()
            if response_json["status_enum"] in ["blocked", "stopped"]:
                return response_json["structured_output"].get("star_count", 0)
        await asyncio.sleep(min(backoff, 30))
        backoff *= 2

async def main():
    """Main function to analyze GitHub repositories."""
    headers = {"Authorization": f"Bearer {API_KEY}"}
    async with aiohttp.ClientSession(headers=headers) as session:
        # Example repositories to analyze
        repos = [
            "https://github.com/openai/openai-python",
            "https://github.com/anthropics/anthropic-sdk-python"
        ]
        
        # Count stars for each repository
        for repo in repos:
            stars = await count_stars(session, repo)
            print(f"{repo}: {stars} stars")

if __name__ == "__main__":
    asyncio.run(main())
