Exploring the Issue: Why the Error Occurs

The root cause of this error is usually an incorrectly formatted API key. Anthropic's API keys follow a specific pattern that must be adhered to for successful authentication. Deviations from this pattern, such as missing characters or incorrect key length, trigger the error.

Step 1: Retrieve the Correct API Key

Log into your Anthropic account and navigate to the API Dashboard. Locate the section where your API keys are listed and ensure you are using the correct key for your application.

Step 2: Verify the Key Format

Check the format of the API key. It should match the expected pattern, which is typically a combination of letters and numbers. Ensure there are no extra spaces or missing characters.

Step 3: Update Your Application

Once you have the correct API key, update your application's configuration to use this key. This might involve editing a configuration file or updating environment variables.

Step 4: Test the Integration

After updating the API key, test your application to ensure that the error is resolved. Make a test API call to verify successful authentication.
