Image generation through the API
Choose the exact model, image size and count. Check the price before generation; the text trial does not fund images.
Use a dedicated API key for each tool. Set a spending limit and verify one small request, then inspect actual usage and cost in your account logs.
Prices depend on model, group, context length and request parameters. Open the complete model contract for dynamic tariffs. A listed price does not guarantee availability or client compatibility.
