Prerequisite: You’ll need an account on Morph to obtain an API key.

​
Authentication

All Morph API endpoints require authentication using Bearer tokens: 
Authorization: Bearer your-morph-api-key
To get your API key:
  1. Visit the Morph dashboard
  2. Create an account or sign in
  3. Navigate to your API keys section
  4. Generate a new API key
Keep your API key secure and never expose it in client-side code or public repositories.

​
Base URL

All Morph API endpoints use the following base URL: 
https://api.morphllm.com/v1

​
Test Your API Key

Verify your setup with a simple test request: 
from openai import OpenAI

client = OpenAI(
    api_key="your-morph-api-key",
    base_url="https://api.morphllm.com/v1"
)

# Test the connection
response = client.chat.completions.create(
    model="morph-v3-fast",
    messages=[{
        "role": "user",
        "content": "<code>def hello():\n    print('Hello World')</code>\n<update>def hello():\n    print('Hello Morph!')</update>"
    }]
)

print(response.choices[0].message.content)
If the test succeeds, you should see the updated code with “Hello Morph!” instead of “Hello World”.
