LangChain tools for Mapsi geospatial APIs — geocoding, routing, isochrone, places

mapsi-langchain

LangChain tools for Mapsi geospatial APIs. One package covers LangChain, CrewAI, AutoGen, and LangGraph.

Install

pip install mapsi-langchain

Get your API key at mapsi.dev/console/api-keys (free tier: 1,000 calls/day).

LangChain

from mapsi_langchain import get_tools
from langchain.agents import initialize_agent, AgentType
from langchain_openai import ChatOpenAI

llm = ChatOpenAI(model="gpt-4o")
agent = initialize_agent(
    get_tools("your-mapsi-api-key"),
    llm,
    agent=AgentType.OPENAI_FUNCTIONS,
)

agent.run("Find the 3 nearest hospitals to 51.5074, -0.1278 and route to the closest one")

CrewAI

from mapsi_langchain import get_tools
from crewai import Agent

geo_agent = Agent(
    role="Geospatial Analyst",
    goal="Answer location questions using real map data",
    tools=get_tools("your-mapsi-api-key"),
)

AutoGen / LangGraph

Both accept standard LangChain tools — pass get_tools("your-key") directly.

OpenAI Agents SDK (function calling)

from mapsi_langchain.openai_tools import MAPSI_TOOLS
import openai

response = openai.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": "Geocode 10 Downing Street London"}],
    tools=MAPSI_TOOLS,
)
