10 Search Engine Results Page (SERP) APIs

Posted in

There’s a saying in the world of data: “Garbage in, garbage out.” Your projects and tools are only as good as the data that drives them. For programmatically finding quality information online, search engine results page (SERP) APIs are one of the most essential tools in your digital toolkit.

SERP APIs can help differentiate your projects and tools from the most popular large language models (LLMs) like ChatGPT, which are trained on historical data rather than real-time results. Real-time data like you get from SERP APIs can make your applications competitive in an AI-driven marketplace.

With that in mind, we’ve put together ten of the best SERP APIs so you can see how real-time data and advanced search functionality can elevate your development.

Its advanced SERP functions are some of its most impressive features, including knowledge graphs, ‘people also asked for,’ and ‘answer boxes.’ It has dedicated endpoints and workflows for nearly all the biggest search engines, including YouTube Search API and LinkedIn Search API.
