Pricing & Billing
Explore this guide to learn how ChatboxAI works and how to integrate it into your workflow.
Pricing & Billing
ChatboxAI uses a unified, real-time Credit-Based Billing System. Instead of managing separate bills for text, images, and audio, everything is deducted from a single US Dollar ($) credit balance.
[!IMPORTANT]
Free Tier Limits: All models marked as "Free" cost exactly $0.00 to use, but they are strictly limited to 300 requests per day and 5 requests per minute (RPM) per account to prevent abuse.
1. How Credit Billing Works
- Purchase Credits: You purchase API Credits (e.g., $10.00) from the Dashboard.
- Make Requests: Every time you make an API request to a Paid model, ChatboxAI calculates the exact cost in USD based on the model and usage (tokens, images, or characters).
- Real-time Deduction: The calculated cost is instantly deducted from your balance.
Every API response header includes your exact remaining balance:
X-API-Credits-Remaining: 9.9995The response JSON body also explicitly shows the cost of that specific API call:
{
"usage": {
"prompt_tokens": 100,
"completion_tokens": 400
},
"cost_usd": 0.00032
}2. Text & Chat Pricing
Text generation is priced per 1,000 tokens (both input and output).

5. Cost Estimation Examples
Example A: Chat Completions (Text)
You send 1,000 input tokens and generate 500 output tokens using the paid chatboxai/claude-4.5-sonnet model:
Input Cost: (1000 / 1000) * $0.0030 = $0.0030
Output Cost: (500 / 1000) * $0.0150 = $0.0075
------------------------------------------------
Total Request Cost: $0.0105Example B: Image Generation
You request 4 high-quality images of "a futuristic city" via chatboxai/image-flux-dev:
Image Cost: 4 images * $0.01 = $0.04
------------------------------------------------
Total Request Cost: $0.046. Subscriptions vs Credits
Understanding how your Subscription Plan interacts with your API Credits:
- Subscription Plan (Free, Pro, Business): Determines your Rate Limits (Requests per Minute and Tokens per Minute), Priority Support access, and access to premium features.
- API Credits: Acts as your wallet to pay for actual API usage when you use Paid models.
