Janitor AI is a popular platform for chatting with AI characters. This guide walks you through connecting MegaNova's API as a backend using OpenAI-compatible endpoints.

### **Requirements**

1. A MegaNova account with API access
2. A[ Janitor AI account](https://janitorai.com/?ref=blog.meganova.ai) (free to sign up)
3. An API key from MegaNova

**Usage Policy:** All integrations must comply with MegaNova's[ Terms of Service](https://docs.meganova.ai/legal-docs/terms-of-service?ref=blog.meganova.ai) and[ Privacy Policy](https://docs.meganova.ai/legal-docs/privacy-policy?ref=blog.meganova.ai), including acceptable use and content guidelines.

### **Integration Steps**

#### **1\. Get Your API Key**

- Log into[ MegaNova AI](https://console.meganova.ai/home?ref=blog.meganova.ai) and go to the API Keys page.
- Copy your default API key and store it somewhere secure.

#### **2\. Open Janitor AI and Choose a Character**

- Head to[ Janitor AI](https://janitorai.com/?ref=blog.meganova.ai).
- You can either:
  - **Create your own character** — click "Create Character" to design a custom personality and backstory, or
  - **Use an existing character** — browse thousands of community-made characters (e.g., Fia) and start a chat.

### **Character Configuration**

When creating or editing a character in Janitor AI:

- Set **API Type** to "OpenAI Compatible"
- Set **Temperature** to 0.7–0.9 (recommended for roleplay)
- Set **Max Tokens** to 2048–4096 (recommended)
- Add character-specific instructions in the **System Message**

### **Advanced Configuration**

#### **Custom System Prompt**

You are \[Character Name\], a \[character description\].

You are engaging in a roleplay conversation.

Stay in character and respond naturally to the user's messages.

### **Temperature Guide**

- **0.7-0.8**: Balanced creativity and consistency
- **0.8-0.9**: More creative and varied responses
- **0.9-1.0**: Maximum creativity (may be less coherent)

### **Troubleshooting**

***API requests failing***

- Double-check your API key and endpoint URL
- Confirm you have sufficient credits in your MegaNova account

***Responses too short or too long***

- Adjust the Max Tokens setting in Janitor AI
- Start at 2048 and tune from there

**Network error or bot won't generate a reply** 

This is a known quirk with proxy setups. Quick fix:

1. Save your proxy configuration
2. Reload the Janitor AI page
3. Reopen your chat and continue — your settings will be preserved

### **Rate Limits**

MegaNova's rate limits depend on your tier:

- **Free tier:** 10 requests per minute
- **Paid tiers:** higher limits — see the[ Tier Overview](https://docs.meganova.ai/tiers?ref=blog.meganova.ai)
