How can I resolve a 403 Disallowed User Agent error when accessing an ML model?

The primary solution is to set a valid and recognized User Agent in your request headers. Check the ML API provider's documentation for the required User Agent string. If they provide an SDK, use it as it will likely handle the User Agent correctly. If no specific User Agent is specified, try setting it to a common browser User Agent (e.g., Chrome, Firefox) as a temporary workaround, but be aware this might violate their terms of service.
