# SpecStream for LangGraph

SpecStream is the live web data engine for teams and agents. Put the langchain-specstream tools in a ToolNode, and your graph searches the live web, reads pages and asks for whole lists, under a price cap the model can't raise.

[Read the guide](https://specstream.ai/docs/integrations/langgraph.md)

## What you get

One ToolNode, four tools

specstream\_tools gives search, page reading, lists and a row reader with one key. tools\_condition routes each call.

A pause before paid work

Send list calls to their own node and compile with interrupt\_before. The graph stops with its state saved until you resume it.

Retries paid once

A retried node that asks for the same list within the hour reaches the list it already started.

## Set it up

1.  Run pip install -U langgraph langchain-specstream and export SPECSTREAM\_API\_KEY with a key from Agents & API.
2.  Bind specstream\_tools(max\_price\_usd=5) to your model and add ToolNode(tools) to a StateGraph with tools\_condition.
3.  Invoke the graph with a question in plain words.
