async function sendMessage(chatbotId, message) {
  const response = await fetch('https://your-domain.com/api/v1/chat', {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.AGENTKIT_API_KEY}`,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      chatbotId,
      messages: [{ role: 'user', content: message }],
    }),
  });

  if (!response.ok) {
    throw new Error(`API error: ${response.status}`);
  }

  const data = await response.json();
  return data.text;
}

Python

import requests

def send_message(chatbot_id: str, message: str) -> str:
    response = requests.post(
        'https://your-domain.com/api/v1/chat',
        headers={
            'Authorization': f'Bearer {API_KEY}',
            'Content-Type': 'application/json',
        },
        json={
            'chatbotId': chatbot_id,
            'messages': [{'role': 'user', 'content': message}],
        },
    )
    response.raise_for_status()
    return response.json()['text']

Node.js with Streaming

async function streamMessage(chatbotId, message) {
  const response = await fetch('https://your-domain.com/api/v1/chat', {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.AGENTKIT_API_KEY}`,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      chatbotId,
      messages: [{ role: 'user', content: message }],
      stream: true,
    }),
  });

  const reader = response.body.getReader();
  const decoder = new TextDecoder();

  while (true) {
    const { done, value } = await reader.read();
    if (done) break;

    const text = decoder.decode(value);
    process.stdout.write(text); // Print as it streams
  }
}

Conversation Management

Starting a Conversation

Omit conversationId to start a new conversation. The response header X-Conversation-ID returns the new ID.

Continuing a Conversation

Include the conversationId and all previous messages to maintain context.

Message History

You must include previous messages in each request. The API is stateless - we don't store conversation history on the server between requests.
