Steps to reproduce

This PR addresses an issue where the application is not calling the correct endpoint to verify the API key.

✔️ Expected Behavior

It should call the correct API endpoint to correctly check the API Key vailidity.

❌ Actual Behavior

It's calling an endpoint which is not defined, thus never being able to verify the API Key.

Hello, @pulgamecanica! I'm here to help you with any bugs, questions, or contributions you have. Let's tackle this API key verification issue together!

To fix the API Key verification endpoint for the SlideSpeak API, ensure that the endpoint URL is correctly constructed and that the API Key is included in the request headers. The endpoint URL should be constructed using the base_url and a test task ID, with the API Key included in the headers as "X-API-Key". Here's a relevant code snippet:

def _validate_credentials(self, credentials: dict[str, Any]) -> None:
    api_key = credentials.get("slidespeak_api_key")
    base_url = credentials.get("base_url")

    if not api_key:
        raise ToolProviderCredentialValidationError("API key is missing")

    if base_url:
        base_url = str(URL(base_url) / "v1")

    headers = {"Content-Type": "application/json", "X-API-Key": api_key}

    test_task_id = "xxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
    url = f"{base_url or 'https://api.slidespeak.co/api/v1'}/task_status/{test_task_id}"

    response = requests.get(url, headers=headers)
    if response.status_code != 200:
        raise ToolProviderCredentialValidationError("Invalid SlidePeak API key")

Ensure that the base_url is correctly set to the SlideSpeak API's base URL, and the API Key is valid and correctly passed in the headers. Additionally, consider using asynchronous requests with aiohttp for better performance, as demonstrated in the SlidesGeneratorTool class ^[1][2].
