    # Cotool API Documentation


    The Cotool API allows you to interact with the Cotool platform
    programmatically, enabling you to build powerful integrations and automate
    your workflows.


    ## Getting an API Key


    Follow these steps to generate your API key:


    1. **Log in** to the Cotool web interface

    2. **Navigate** to `/settings/api-keys`

    3. **Click** "Generate Key"

    4. **Copy and store** your API key securely ⚠️ *It won't be shown again*


    ## API Key Authentication


    For programmatic access and integrations, use your API key with the
    Authorization header:


    ```http

    Authorization: Bearer your_api_key_here

    ```


    ```bash

    curl -X GET "https://app.cotool.ai/api/endpoint" \
      -H "Authorization: Bearer your_api_key_here" \
      -H "Content-Type: application/json"
    ```
