# Serp API Tool

The [Serp API](https://serpapi.com/) (Search Engine Results Page) allows developers to scrape results from search engines such as Google, Bing and Yahoo, and can be used as in Langflow through the `Search` component.

<Admonition type="info">
  To use the Serp API, you first need to sign up [Serp
  API](https://serpapi.com/) for an API key on the provider's website.
</Admonition>

Here, the `ZeroShotPrompt` component specifies a prompt template for the `ZeroShotAgent`. Set a _Prefix_ and _Suffix_ with rules for the agent to obey. In the example, we used default templates.

The `LLMChain` is a simple chain that takes in a prompt template, formats it with the user input, and returns the response from an LLM.

<Admonition type="tip">
  In this example, we used [`ChatOpenAI`](https://platform.openai.com/) as the
  LLM, but feel free to experiment with other Language Models!
</Admonition>

The `ZeroShotAgent` takes the `LLMChain` and the `Search` tool as inputs, using the tool to find information when necessary.
