How to parse Google search results without blocking (PHP + cURL)?

Question

Google

I parse the output of Google (only the first page of the output), after about 30 requests, Google dumps the captcha. Is it possible to parse without blocking, without using a proxy? It is necessary that ~ 1500 requests be processed in no more than three hours.
I set pauses between requests, sent browser-like headers.

Answer 1

There is an XMLRiver
service ~ 1500 requests can be collected in 10 minutes.

Answer 2

Never
Use an API
Use a bunch of proxies
Use a real browser
....

Answer 3

No, and moreover, a proxy, and even more so a VPS / VDS, may already be present in the list so that the captcha appears on almost every second request.

Answer 4

Pay for captcha and don't worry

Answer 5

На днях написали статью "How to check which URLs have been indexed by Google using Python"
Тут имеется в виду парсинг по списку URL, можно подшаманить и парсить по запросу.

Answer 6

Парсить с одного IP без блокировок не получится, но можно настроить сетку проксей на одну геолокацию для ровных результатов. А можно купить услуги готовых сервисов, например serpentine.io.
