+## SearchApi API
+
+[SearchApi](https://searchapi.io) is a collection of real-time SERP APIs. Any existing or upcoming SERP engine that returns `organic_results` is supported. The default web search engine is `google`, but it can be changed to `bing`, `baidu`, `google_news`, `bing_news`, `google_scholar`, `google_patents`, and others.
+
+### Setup
+
+1. Go to [SearchApi](https://searchapi.io), and log on or create a new account.
+2. Go to `Dashboard` and copy the API key.
+3. With `API key`, open `Open WebUI Admin panel` and click `Settings` tab, and then click `Web Search`.
+4. Enable `Web search` and set `Web Search Engine` to `searchapi`.
+5. Fill `SearchApi API Key` with the `API key` that you copied in step 2 from [SearchApi](https://www.searchapi.io/) dashboard.
