langchain-anakin

LangChain tools for Anakin: web scraping, site mapping and crawling, AI search, multi-stage agentic research, and Wire (pre-built structured actions for hundreds of sites). Built on the official anakin-sdk Python client (not a separate HTTP implementation).

Install

pip install -U langchain-anakin
export ANAKIN_API_KEY="ask-..."   # free at https://anakin.io/signup

No key yet? AnakinScrapeTool, AnakinWireDiscoverTool and AnakinWireRunTool (read-only actions) work without one on a free per-IP allowance. The other tools return a ConfigurationError message with a signup link.

Tools

from langchain_anakin import (
    AnakinScrapeTool,
    AnakinSearchTool,
    AnakinWireDiscoverTool,
    AnakinWireRunTool,
)

AnakinScrapeTool().invoke({"url": "https://example.com"})

AnakinScrapeTool().invoke({
    "url": "https://example.com/product",
    "output_schema": {"type": "object", "properties": {"price": {"type": "number"}}},
})

AnakinSearchTool().invoke({"prompt": "latest developments in AI agents"})

actions = AnakinWireDiscoverTool().invoke({"query": "search products on walmart"})
AnakinWireRunTool().invoke({"action_id": "walmart_search", "params": {"query": "phones"}})

Every tool also supports async (await tool.ainvoke(...)), backed by anakin.AsyncAnakin.

Use with an agent:

from langchain.agents import create_agent
from langchain_anakin import (
    AnakinScrapeTool,
    AnakinSearchTool,
    AnakinWireDiscoverTool,
    AnakinWireRunTool,
)

agent = create_agent(
    model,
    tools=[
        AnakinSearchTool(),
        AnakinScrapeTool(),
        AnakinWireDiscoverTool(),
        AnakinWireRunTool(),
    ],
)

Errors (bad key, no credits, a Wire site that needs a connected account) come back to the agent as text instead of raising, including any URL it needs to fix the problem.

Development

Requires anakin-sdk 0.2.x.
