We'll see it's a viable approach to start working with a massive API spec AND to assist with user queries that require multiple steps against the API.The idea is simple: to get coherent agent behavior over long sequences behavior & to save on tokens, we'll separate concerns: a "planner" will be responsible for what endpoints to call and a "controller" will be responsible for how to call them.In the initial implementation, the planner is an LLM chain that has the name and a short description for each endpoint in context. The controller is an LLM agent that is instantiated with documentation for only the endpoints for a particular plan. There's a lot left to get this working very robustly :)To start, let's collect some OpenAPI specs.â€‹import os, yamlwget https://raw.githubusercontent.com/openai/openai-openapi/master/openapi.yamlmv openapi.yaml openai_openapi.yamlwget

GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools.By including a BaseGraphQLTool in the list of tools provided to an Agent, you can grant your Agent the ability to query data from GraphQL APIs for any purposes you need.In this example, we'll be using the public Star Wars GraphQL API available at the following endpoint: https://swapi-graphql.netlify.app/.netlify/functions/index.First, you need to install httpx and gql Python packages.pip install httpx gql > /dev/nullNow, let's create a BaseGraphQLTool instance with the specified Star Wars API endpoint and initialize an Agent with the tool.from langchain import OpenAIfrom langchain.agents import load_tools, initialize_agent,

Let's ask the Agent to list all the Star Wars films and their release dates.graphql_fields = """allFilms {    films {      title      director      releaseDate      speciesConnection {        species {          name          classification          homeworld {            name          }        }      }    }  }"""suffix = "Search for the titles of all the stawars films stored in the graphql database that has this schema "agent.run(suffix + graphql_fields)            > Entering new AgentExecutor chain...
