To avoid HTTP 400 errors when calling the Google Generative AI API, validate request payloads by ensuring they meet the expected format, required fields, and data types before sending them.
Here is the code snippet you can refer to:

In the above code we are using the following points:
- String Input Validation: Ensures the prompt is a non-empty string.
- Proper API Configuration: Sets GOOGLE_API_KEY using environment variables.
- Error Handling: Raises a ValueError for incorrect payloads.
- Prevents API Misuse: Avoids sending malformed requests that may trigger HTTP 400 errors.
Hence, validating payloads before making API calls, ensuring correct data types, and handling errors properly help prevent HTTP 400 errors when using the Google Generative AI API.
