| 11 | +### TavilyWebSearch |
| 12 | + |
| 13 | +A component that uses Tavily to search the web and return results as Haystack Documents. |
| 14 | + |
| 15 | +This component wraps the Tavily Search API, enabling web search queries that return |
| 16 | +structured documents with content and links. |
| 17 | + |
| 18 | +Tavily is an AI-powered search API optimized for LLM applications. You need a Tavily |
| 19 | +API key from [tavily.com](https://tavily.com). |
| 20 | + |
| 21 | +### Usage example |
| 22 | + |
| 23 | +```python |
| 24 | +from haystack_integrations.components.websearch.tavily import TavilyWebSearch |
| 25 | +from haystack.utils import Secret |
| 26 | + |
| 27 | +websearch = TavilyWebSearch( |
| 28 | + api_key=Secret.from_env_var("TAVILY_API_KEY"), |
| 29 | + top_k=5, |
| 30 | +) |
| 31 | +result = websearch.run(query="What is Haystack by deepset?") |
| 32 | +documents = result["documents"] |
| 33 | +links = result["links"] |
| 34 | +``` |
| 35 | + |
| 36 | +#### __init__ |
| 37 | + |
| 38 | +```python |
| 39 | +__init__( |
| 40 | + api_key: Secret = Secret.from_env_var("TAVILY_API_KEY"), |
| 41 | + top_k: int | None = 10, |
| 42 | + search_params: dict[str, Any] | None = None, |
| 43 | +) -> None |
| 44 | +``` |
| 45 | + |
| 46 | +Initialize the TavilyWebSearch component. |
| 47 | + |
| 48 | +**Parameters:** |
| 49 | + |
| 50 | +- **api_key** (<code>Secret</code>) – API key for Tavily. Defaults to the `TAVILY_API_KEY` environment variable. |
| 51 | +- **top_k** (<code>int | None</code>) – Maximum number of results to return. |
| 52 | +- **search_params** (<code>dict\[str, Any\] | None</code>) – Additional parameters passed to the Tavily search API. |
| 53 | + See the [Tavily API reference](https://docs.tavily.com/docs/tavily-api/rest_api) |
| 54 | + for available options. Supported keys include: `search_depth`, `include_answer`, |
| 55 | + `include_raw_content`, `include_domains`, `exclude_domains`. |
| 56 | + |
| 57 | +#### warm_up |
| 58 | + |
| 59 | +```python |
| 60 | +warm_up() -> None |
| 61 | +``` |
| 62 | + |
| 63 | +Initialize the Tavily sync and async clients. |
| 64 | + |
| 65 | +Called automatically on first use. Can be called explicitly to avoid cold-start latency. |
| 66 | + |
| 67 | +#### run |
| 68 | + |
| 69 | +```python |
| 70 | +run(query: str, search_params: dict[str, Any] | None = None) -> dict[str, Any] |
| 71 | +``` |
| 72 | + |
| 73 | +Search the web using Tavily and return results as Documents. |
| 74 | + |
| 75 | +**Parameters:** |
| 76 | + |
| 77 | +- **query** (<code>str</code>) – Search query string. |
| 78 | +- **search_params** (<code>dict\[str, Any\] | None</code>) – Optional per-run override of search parameters. |
| 79 | + If provided, fully replaces the init-time `search_params`. |
| 80 | + |
| 81 | +**Returns:** |
| 82 | + |
| 83 | +- <code>dict\[str, Any\]</code> – A dictionary with: |
| 84 | +- `documents`: List of Documents containing search result content. |
| 85 | +- `links`: List of URLs from the search results. |
| 86 | + |
| 87 | +#### run_async |
| 88 | + |
| 89 | +```python |
| 90 | +run_async( |
| 91 | + query: str, search_params: dict[str, Any] | None = None |
| 92 | +) -> dict[str, Any] |
| 93 | +``` |
| 94 | + |
| 95 | +Asynchronously search the web using Tavily and return results as Documents. |
