Amadeus

This notebook walks you through connecting LangChain to the Amadeus travel APIs.

This Amadeus toolkit allows agents to make decision when it comes to travel, especially searching and booking trips with flights.

To use this toolkit, you will need to have your Amadeus API keys ready, explained in the Get started Amadeus Self-Service APIs. Once you’ve received a AMADEUS_CLIENT_ID and AMADEUS_CLIENT_SECRET, you can input them as environmental variables below.

Note: Amadeus Self-Service APIs offers a test enviornment with free limited data. This allows developers to build and test their applications before deploying them to production. To access real-time data, you will need to move to the production environment.

!pip install --upgrade amadeus > /dev/null

Assign Environmental Variables​

The toolkit will read the AMADEUS_CLIENT_ID and AMADEUS_CLIENT_SECRET environmental variables to authenticate the user so you need to set them here. You will also need to set your OPENAI_API_KEY to use the agent later.

# Set environmental variables here
import os

os.environ["AMADEUS_CLIENT_ID"] = "CLIENT_ID"
os.environ["AMADEUS_CLIENT_SECRET"] = "CLIENT_SECRET"
os.environ["OPENAI_API_KEY"] = "API_KEY"
# os.environ["AMADEUS_HOSTNAME"] = "production" or "test"

Create the Amadeus Toolkit and Get Tools​

To start, you need to create the toolkit, so you can access its tools later.

from langchain_community.agent_toolkits.amadeus.toolkit import AmadeusToolkit

toolkit = AmadeusToolkit()
tools = toolkit.get_tools()

Use Amadeus Toolkit within an Agent​

from langchain.agents import AgentType, initialize_agent

llm = OpenAI(temperature=0)
agent = initialize_agent(
    tools=tools,
    llm=llm,
    verbose=False,
    agent=AgentType.STRUCTURED_CHAT_ZERO_SHOT_REACT_DESCRIPTION,
)
