Colossal: The Global Directory of Ready-to-Use LLM Agents

What is Colossal? Colossal is a comprehensive platform designed to streamline the integration of AI agents into Large Language Model (LLM) applications. It serves as the largest global directory of pre-made, tool-using agents, allowing developers to skip the time-consuming process of building their own tools and instead connect to agents that can perform API calls with a single fetch.

Key Features:

  • Global Directory: Colossal hosts an extensive collection of ready-to-use LLM agents.
  • API Integration: Connect to AI agents capable of performing API calls.
  • Tool-Using Agents: Agents are designed to interact with various tools and services.
  • Simplified Integration: Integrate agents into your applications with a single API request.

How does Colossal work?

Colossal simplifies the integration of AI agents into your LLM applications through a straightforward API-driven approach. Here's how it works:

  1. Browse the Directory: Explore the Colossal directory to find agents that match your application's needs. Agents are categorized by the services they interact with, such as Zendesk, Twilio, Slack, Square, and QuickBooks.
  2. Integrate with a Single Fetch: Once you've identified an agent, integrate it into your application using a simple curl request. This involves providing the necessary credentials for both the provider (e.g., OpenAI) and the agent (e.g., Zendesk).
  3. Interact with the Agent: Send user messages to the agent and receive responses that leverage the agent's tool-using capabilities. Colossal handles the orchestration of API calls and returns the results in a structured format.

Supported Agents:

Colossal offers a variety of pre-built agents for popular services, including:

  • Zendesk: Automate support ticket management with agents that can create and update tickets.
  • Twilio: Send and receive SMS and email messages programmatically.
  • Slack: Interact with Slack channels by creating threads and sending messages.
  • Square: Manage orders and catalog operations within your Square account.
  • QuickBooks: Handle financial data and invoice operations seamlessly.

Example Usage:

Here's an example of how to integrate the Zendesk agent using a curl request:

curl -X POST \
  https://colossalhq.com/api/v1/agents/zendesk \
  -H 'Content-Type: application/json' \
  -H 'Accept: text/plain' \
  -H 'Authorization: Bearer <COLOSSAL_API_TOKEN>' \
  -d '{
    "provider": "openai",
    "providerCredentials": {
      "apiKey": "<OPENAI_TOKEN>"
    },
    "agentCredentials": {
      "subdomain": "my-zendesk-subdomain",
      "email": "my-zendesk-email", 
      "apiToken": "<ZENDESK_API_TOKEN>"
    },
    "options": {
      "toolCallStreaming": true,
      "maxSteps": 10
    },
    "metadata": {
      "messages": [
        {
          "role": "user",
          "content": "Hey, I need help with my order"
        }
      ],
      "userInfo": {
        "name": "Jonathan Qwilao",
        "email": "jonathan@colossalhq.com"
      }
    }
  }'

This request sends a user message to the Zendesk agent, which then creates a ticket and responds with the ticket ID.
