Code Completion

Introduction

Show the code completion for a specific text input.

Request

Show the code completion for a specific text input. The /ai/tools/complete API accepts requests in the following format:

CodeCompletionRequest Model - Request to show code completion for a specific text input.
language string Enum
required
example: Py
Programming language for the code completion. Options : ['C#', 'Py']
sentence string
required
example: self.add_equity(\"AAPL\"
Sentence to complete.
responseSizeLimit integer
example: 10
Maximum size of the responses.
Example 
{
  "language": "Py",
  "sentence": "self.add_equity(\"AAPL\"",
  "responseSizeLimit": 10
}

Responses

The /ai/tools/complete API provides a response in the following format:

200 Success

CodeCompletionResponse Model - Response to a code completion request.
state string
example: End
State of the code completion.
version string
example: 2.0
Version of the response.
payload string Array
Code completion suggestions.
payloadType string
example: StringArray
Type of the payload, e.g. StringArray.
Example 
{
  "state": "End",
  "version": 2.0,
  "payload": [
    "string"
  ],
  "payloadType": "StringArray"
  ]
}

401 Authentication Error

UnauthorizedError Model - Unauthorized response from the API. Key is missing, invalid, or timestamp is too old for hash.
www_authenticate string
Header

Examples

The following example demonstates code completion for a specific algorithm attribute through the cloud API.

from base64 import b64encode
from hashlib import sha256
from time import time
from requests import get, post
BASE_URL = 'https://www.quantconnect.com/api/v2/'

# You need to replace these with your actual credentials.
# You can request your credentials at https://www.quantconnect.com/settings/
# You can find our organization ID at https://www.quantconnect.com/organization/ 
USER_ID = 0
API_TOKEN = '____'
ORGANIZATION_ID = '____'

def get_headers():
    # Get timestamp
    timestamp = f'{int(time())}'
    time_stamped_token = f'{API_TOKEN}:{timestamp}'.encode('utf-8')

    # Get hased API token
    hashed_token = sha256(time_stamped_token).hexdigest()
    authentication = f'{USER_ID}:{hashed_token}'.encode('utf-8')
    authentication = b64encode(authentication).decode('ascii')

    # Create headers dictionary.
    return {
        'Authorization': f'Basic {authentication}',
        'Timestamp': timestamp
    }

# Authenticate to verify credentials
response = post(f'{BASE_URL}/authenticate', headers = get_headers())
print(response.json())

# --------------------


### Code Completion
# Send a POST request to the /ai/tools/complete endpoint to get code completion
response = post(f'{BASE_URL}/ai/tools/complete', headers=get_headers(), json={
    "language": "Python",  # Programming language for code completion
    "sentence": "self.add_equity('AAPL",  # Partial code to complete
    "responseSizeLimit": 30  # Maximum size of the completion response
})
# Parse the JSON response
result = response.json()
# Check if the request was successful and print the code completion results
if result['success']:
    print("Code Completion Results:")
    print(result)
