Disclaimer: I work at SerpApi.

You now have to use the Google Search API to make your GET requests.

All other methods have been blocked.

You can load it in the browser and then scrape results via Javascript.

Or you can use Google API, but seems that it requires payment if you will request it more then 100 times per day.

To add a bit more sauce to the answers as they are not correct and do not even respond to your problem.

First of all, it's perfectly legal to scrape Google as long as you do not harm their service through it (DoS-like).
Also the methods have not been blocked, it's just not that simple.

The speed depends on your methods, it does not have to be very slow..
You can scrape ten thousands of keyword pages in a minute if needed.

You will find a better answer to the topic here: Is it ok to scrape data from Google results?

Your problem with curl comes indeed from protection, Google does not allow automated access and it has a very sophisticated set of detection algorithms.
They go from simple user agent checks (that's what stopped you directly) up to artificial intelligence that tries to detect unusual queries or related queries.
