langchain-netcafe

LangChain tools that hand back finished files — PDF, docx, chart PNG, SRT subtitles, invoices, screenshots — from one hosted endpoint. Free quota, no API key to start.

pip install langchain-netcafe

from langchain_netcafe import get_netcafe_tools

tools = get_netcafe_tools()                # anonymous free quota
# tools = get_netcafe_tools(api_key="sk-...")   # unlimited, billed to you

# use with any LangChain / LangGraph agent:
from langgraph.prebuilt import create_react_agent
agent = create_react_agent("openai:gpt-4o-mini", tools)

Works with CrewAI out of the box (CrewAI consumes LangChain tools directly):

from crewai import Agent
Agent(role="analyst", tools=get_netcafe_tools(), ...)

What's inside

14 curated tools (search, screenshot→PNG, markdown→PDF/docx, charts, QR, audio→SRT, invoice→PDF, meeting minutes, flashcards→Anki CSV, SQL, Dockerfile, diagrams, transcription) plus netcafe_call(tool, params) to reach all 43+ outcome tools: https://ainetcafe.com/tools

Every call reports its real metered cost. Beyond the free quota: pay-per-call (x402/USDC for agents, Stripe for humans) or bring an AllRouter key.
