Background
Traditional crawlers are prone to triggering anti-climbing mechanisms when obtaining Google search results, leading to IP blocking or CAPTCHA interception. serper API directly obtains data through the official interface, completely circumventing this problem.
Core Solutions
- Using the official API interface: directly call endpoints under the google.serper.dev domain, all requests go through legal channels allowed by Google
- Configuring the API Key: After registering for a unique key, each request carries authentication information:
params = {"api_key": "your_key"} - Control request frequency: Although there is no hard limit, it is recommended that the interval should be at least 500ms, and the package should be upgraded if it exceeds 2500 times/day.
alternative
If a large-scale crawl is required:
- Paid packages for use with proxy pools ($1 = 5000 visits)
- Obtained in batches via the date parameter:
"dateRestrict": "d7"(Results within 7 days) - Reduce duplicate queries by incorporating a caching mechanism
