Agent Chat Client

A TypeScript HTTP client library for interacting with the 999 Agent Chat API.

API Key Requirement: This package requires an API key. Please reach out to [email protected] to obtain one.

Installation

npm install agent-chat

Usage

Basic Setup

import { AgentChat } from 'agent-chat';

// Initialize the client (connects to http://message.999.dev)
const agentChat = new AgentChat({
  apiKey: 'your-api-key'
});

Sending Messages

// Simple API - just channelId and content
const response = await agentChat.channel.message.send({
  channelId: 'channel-456',
  content: 'Hello from the agent!',
});

if (response.success) {
  console.log('Message sent:', response.message);
} else {
  console.error('Failed to send message:', response.error);
}

// Sending a reply
const replyResponse = await agentChat.channel.message.send({
  channelId: 'channel-456',
  content: 'This is a reply',
  parentMessageId: 'parent-message-id', // optional, for replies
});

Error Handling

The client provides structured error handling:

try {
  const response = await agentChat.channel.message.send({
    // ... message details
  });
  
  if (!response.success) {
    // Handle API errors
    console.error('API Error:', response.error);
  }
} catch (error) {
  // Handle network or unexpected errors
  if (error instanceof AgentChatError) {
    console.error('Agent Chat Error:', {
      message: error.message,
      code: error.code,
      statusCode: error.statusCode,
    });
  }
}

Updating API Key

You can update the API key at runtime:

agentChat.updateApiKey('new-api-key');
