🤖 GraphQL + LLM: A Match Made in AI Heaven

Welcome to the world of AI-powered GraphQL! This guide will show you how to bind the GraphQL Agent Tool with your LLM models. It's like giving your GraphQL tools a brain! 🧠

The Big Picture 🎨

The GraphQL Agent Tool can be bound with any LLM that supports tool calling. This enables your LLM to:

Understand when to use GraphQL operations
Construct appropriate queries and mutations
Handle responses intelligently
Chain multiple operations together

Binding the Tool with Your LLM 🤝

Here's how to bind the GraphQL Agent Tool with your LLM:

import { GraphqlAgentTool } from "graphql-agent-tool";
import { YourLLM } from "your-llm-package";

// Create a GraphQL tool for country information
const countryInfoTool = new GraphqlAgentTool({
  name: "getCountryInfo",
  purpose: "Retrieves information about countries including capital, population, and languages...",
  url: "https://countries.trevorblades.com",
  query: `
    query GetCountryInfo($countryCode: ID!) {
      country(code: $countryCode) {
        capital
        population
        languages {
          name
        }
      }
    }
  `,
}).getTool();

// Create a GraphQL tool for space information
const spaceInfoTool = new GraphqlAgentTool({
  name: "getSpaceInfo",
  purpose: "Retrieves information about space missions and launches...",
  url: "https://api.spacex.land/graphql",
  query: `
    query GetLaunches($limit: Int!) {
      launches(limit: $limit) {
        mission_name
        launch_date_local
        launch_site {
          site_name_long
        }
      }
    }
  `,
}).getTool();

// Create a GraphQL tool for movie information
const movieInfoTool = new GraphqlAgentTool({
  name: "getMovieInfo",
  purpose: "Retrieves information about movies including title, release date, and cast...",
  url: "https://tmdb.sandbox.zoosh.ie/graphql",
  query: `
    query GetMovie($id: ID!) {
      movie(id: $id) {
        title
        releaseDate
        cast {
          name
          character
        }
      }
    }
  `,
}).getTool();

// Bind the tools with your LLM
const llm = new YourLLM({
  tools: [countryInfoTool, spaceInfoTool, movieInfoTool],
});

// The LLM can now use these tools autonomously
const response = await llm.chat("What's the capital of India and when was the last SpaceX launch?");

Available Open GraphQL APIs 🌐

Here are some free, open GraphQL APIs you can use with the tool:

Countries API
- URL: https://countries.trevorblades.com
- Purpose: Country information, capitals, languages, etc.
- Example Query: Get country details by code
SpaceX API
- URL: https://api.spacex.land/graphql
- Purpose: Space missions, launches, rockets
- Example Query: Get recent launches
TMDB GraphQL
- URL: https://tmdb.sandbox.zoosh.ie/graphql
- Purpose: Movie information, actors, reviews
- Example Query: Get movie details
Rick and Morty API
- URL: https://rickandmortyapi.com/graphql
- Purpose: Character information, episodes, locations
- Example Query: Get character details
AniList API
- URL: https://graphql.anilist.co
- Purpose: Anime and manga information
- Example Query: Get anime details

How It Works 🧐

You create GraphQL tools with specific purposes
Bind these tools with your LLM
The LLM understands when to use each tool
The LLM constructs appropriate queries
The tools execute the queries
The LLM processes the responses

Why This Is Amazing 🌟

Autonomous Operations: LLMs can determine when to use GraphQL
Multiple APIs: Support for various GraphQL endpoints
Type Safety: TypeScript keeps everything type-safe
Flexible: Works with any LLM that supports tool calling
Extensible: Easy to add new GraphQL tools

Pro Tips 💡

Clear Purpose: Write clear purpose descriptions for each tool
Response Parsing: Use response parsers to help LLMs understand the data
Error Handling: Implement proper error handling in your tools
Rate Limits: Be mindful of API rate limits
Tool Selection: Choose tools that complement each other
