langchain-netnest

LangChain tools for the NetNest Design Fundamentals API: company fundamentals and SEC filing events, with the source filing on every number.

pip install langchain-netnest
from langchain_netnest import NetNestToolkit
from netnest_fundamentals import NetNestClient

tools = NetNestToolkit(client=NetNestClient("demo")).get_tools()  # or your key; defaults to NETNEST_API_KEY
# give tools to create_agent(model, tools) or any tool calling model
  • Tools: netnest_search_company, netnest_get_company, netnest_get_fundamentals, netnest_get_history, netnest_get_events, netnest_get_events_head. Each returns the API's JSON as a string.
  • An API refusal (unknown ticker, a limit) comes back as {"error": {...}} for the model to read, not an exception.
  • Each tool is also importable on its own, for example NetNestFundamentals(client=...).
