metalift-langchain 1.0.0

LangChain tools for the Metalift web context API

Metalift LangChain integration

LangChain tools for Metalift — a hosted web context API that turns URLs into LLM-ready markdown for agents. This package wraps the Metalift REST API; it does not use @langchain/community RecursiveUrlLoader or any local server-side HTTP fetch of user-supplied URLs.

Get an API key

1. Sign up for Metalift Cloud and verify your email.
2. Complete onboarding on the dashboard.
3. Copy your API key from Dashboard → API keys.

New accounts receive 1,000 free credits/month on the Free tier. Use the hosted API at https://api.metalift.ai, or point api_url at your own self-hosted scrape API.

Do not commit API keys into source code — pass them at runtime or via the METALIFT_API_KEY environment variable.

Security

• All URL fetching runs on the Metalift scrape API with SSRF guards: manual redirect validation, private/metadata IP blocklist, DNS pinning, and Playwright egress isolation.
• Do not use LangChain's built-in RecursiveUrlLoader (or similar loaders with automatic redirect following) for untrusted URLs — see CVE-2026-27795 and Metalift security.

Usage

pip install metalift-langchain

from metalift_langchain import get_metalift_tools

tools = get_metalift_tools(api_url="https://api.metalift.ai", api_key="YOUR_API_KEY")

Requires the metalift-sdk package and a reachable Metalift scrape API.
