Tools are utilities designed to be called by a model: their inputs are designed to be generated by models, and their outputs are designed to be passed back to models.

• The LangChain integration documentation provides basic information about the tools, but gathering complete, up-to-date information requires additional steps. This includes details about subscriptions, regional API availability, and support for different models. I propose enhancing the documentation structure by adding filterable tables with key parameters (e.g., regional availability, cost) to simplify integration for developers.

Adding Crawl4 ai will be amazing it be used as KB

[danni-boii]

You can customise your own tool using crawl4ai like this.

import crawl4ai
from langchain_core.tools import StructuredTool
from pydantic import BaseModel, Field

config = crawl4ai.CrawlerRunConfig()

async def crawl_by_url(url: str):
    async with crawl4ai.AsyncWebCrawler() as crawler:
        results = await crawler.arun_many(
            urls=[url],
            config=config,
        )

        result_in_markdown = [
            {
                "url": result.url,
                "markdown": result._markdown.markdown_with_citations
                if result._markdown
                else "No data",
            }
            for result in results
        ]

        return result_in_markdown

class InputSchema(BaseModel):
    url: str = Field(..., title="URL", description="The URL of the webpage to crawl.")

# Or simply use the annotation @tool
web_crawl_tool = StructuredTool.from_function(
    coroutine=crawl_by_url,
    name="web_crawl",
    description="Browse webpage content by the url and return the content.",
    input_schema=InputSchema,
)

Wolframalpha code not working

[maxiller]

Google Serper is not free, actually. It offers 2500 queries per month for free.

[edurodriguesdias]

You can try DuckDuckGo! It's completely free and works well.

아 사람 짜증나게 하네.

형님들. 카테고리 분류 좀 제대로 좀 해봐.

보기 너무 불편해 죽겠어. parameter 설명도 좀 적으라고 시키던가. 아니면 설명 양식을 좀 통일 시키던가 아 진짜 모니터 부수고 싶네
