🧪 API Playground

Simulate AI API calls and see exactly what they'll cost. Compose prompts, pick models, adjust parameters — no API key needed.

Frequently Asked Questions

Does the API Playground make real API calls?

No. The playground simulates API requests and estimates costs based on token counts and current pricing. No actual API calls are made and no API key is needed.

How are tokens counted?

We estimate tokens by counting words and multiplying by 1.3. For precise counts, use the official tokenizer for your chosen model.

Can I compare costs across models?

Yes! After composing your prompt, you can switch between models to see how costs differ. Or use our Batch Calculator to compare all models at once.

What parameters can I adjust?

You can set the system prompt, user message, expected output length, temperature, max tokens, and number of requests to estimate daily/monthly costs.
