So, my question is simple: how do you solve the problem? I've tried searxng with mediocre success, but it seems a bit heavy to have to be running a complete separate service for this one thing that I only need every once in a while. I haven't tried using a service that requires an API key, simply because I'm not sure which direction to go or who to go with.
Just thought I would ask here first.
(Assuming you prefer Python.)
Try again, but have curl provide a user agent string from one of the real browsers. You'll likely find that the request goes through.
