# FirecrawlWebSearch
Search the web and extract content using the Firecrawl API.

## Overview
When you give `FirecrawlWebSearch` a query, it uses the Firecrawl Search API to search the web, crawl the resulting pages, and return the structured text as a list of Haystack `Document` objects. It also returns a list of the underlying URLs.
Because Firecrawl actively scrapes and structures the content of the pages it finds into LLM-friendly formats, you generally don't need an additional component like `LinkContentFetcher` to read the web pages. `FirecrawlWebSearch` handles the retrieval and scraping all in one step.
`FirecrawlWebSearch` requires a [Firecrawl](https://firecrawl.dev) API key to work. By default, it looks for a `FIRECRAWL_API_KEY` environment variable. Alternatively, you can pass an `api_key` directly during initialization.
## Usage
### On its own
Here is a quick example of how `FirecrawlWebSearch` searches the web based on a query, scrapes the resulting web pages, and returns a list of Documents containing the page content.
```python
from haystack_integrations.components.websearch.firecrawl import FirecrawlWebSearch
from haystack.utils import Secret
web_search = FirecrawlWebSearch(
api_key=Secret.from_env_var("FIRECRAWL_API_KEY"),
top_k=5,
search_params={"scrape_options": {"formats": ["markdown"]}},
)
query = "What is Haystack by deepset?"
response = web_search.run(query=query)
for doc in response["documents"]:
print(doc.content)
```
### In a pipeline
Here is an example of a Retrieval-Augmented Generation (RAG) pipeline where using `FirecrawlWebSearch` to look up an answer. Because Firecrawl returns the actual text of the scraped pages, you can pass its `documents` output directly into the `ChatPromptBuilder` to give the LLM the necessary context.
```python
from haystack import Pipeline
from haystack.utils import Secret
from haystack.components.builders.chat_prompt_builder import ChatPromptBuilder
from haystack.components.generators.chat import OpenAIChatGenerator
from haystack_integrations.components.websearch.firecrawl import FirecrawlWebSearch
from haystack.dataclasses import ChatMessage
web_search = FirecrawlWebSearch(
api_key=Secret.from_env_var("FIRECRAWL_API_KEY"),
top_k=2,
search_params={"scrape_options": {"formats": ["markdown"]}},
)
prompt_template = [
ChatMessage.from_system("You are a helpful assistant."),
ChatMessage.from_user(
"Given the information below:\n"
"{% for document in documents %}{{ document.content }}\n{% endfor %}\n"
"Answer the following question: {{ query }}.\nAnswer:",
),
]
prompt_builder = ChatPromptBuilder(
template=prompt_template,
required_variables={"query", "documents"},
)
llm = OpenAIChatGenerator(
api_key=Secret.from_env_var("OPENAI_API_KEY"),
model="gpt-5-nano",
)
pipe = Pipeline()
pipe.add_component("search", web_search)
pipe.add_component("prompt_builder", prompt_builder)
pipe.add_component("llm", llm)
pipe.connect("search.documents", "prompt_builder.documents")
pipe.connect("prompt_builder.prompt", "llm.messages")
query = "What is Haystack by deepset?"
result = pipe.run(data={"search": {"query": query}, "prompt_builder": {"query": query}})
print(result["llm"]["replies"][0].text)
```
