Our REST API gives you the power to integrate AI chatbot capabilities into any application

# Send a message to AI
curl -X POST https://asyntai.com/api/v1/chat/ \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"message": "What are your hours?"}'

Simple REST API

A single API endpoint to send messages and get AI responses. Use cURL, Python, JavaScript, or any language that can make HTTP requests. No complex SDKs required.

# AI Response
{
  "success": true,
  "response": "We're open Monday-Friday,
    9am-6pm EST. How can I help?"
,
  "session_id": "abc123"
}

Intelligent Responses

The AI knows your business inside out. It learns from your website, documents, and custom instructions to provide accurate, contextual answers to any question.

# Conversation with context
{
  "message": "What was my last question?",
  "session_id": "user_12345"
}

Frequently Asked Questions

Everything you need to know about the AI Chatbot API

How do I get started with the API?
Click here to get your API key. Create an account, enter your website URL (so the AI learns about your business), and generate your API key. Then make your first request using cURL, Python, JavaScript, or any HTTP client.
What programming languages are supported?
Any language that can make HTTP requests works with our API. This includes Python, JavaScript, PHP, Ruby, Java, C#, Go, Swift, Kotlin, and many more. We provide code examples in our documentation.
How does conversation context work?
Include a session_id parameter in your requests. The AI will remember all previous messages in that session and provide contextual responses. Use any unique identifier for each user or conversation.
How does the AI know about my business?
You can teach the AI about your business by uploading your website URL (we'll crawl it automatically), uploading documents (PDFs, text files), adding custom instructions, or providing specific Q&A pairs. All this is done through the dashboard - no API changes needed.
What are the rate limits?
Rate limits depend on your plan. The API is designed for real-time chat applications. If you need higher limits for your use case, contact us and we'll work with you.
Is the API secure?
Yes. All API requests use HTTPS encryption. Your API key should be kept secret and never exposed in client-side code. We recommend making API calls from your backend server.
