Workflow

1. Generate — POST creates the gamma, returns a generationId 2. Poll — Use --wait or manually check status until completed 3. Result — Completed response includes gammaUrl (live link) and export download URL if requested 4. Credits — Response shows credits.deducted and credits.remaining

Input Tips

Short prompts work ("AI trends 2026") but detailed structured text produces better results

Insert image URLs directly in inputText where you want them placed

Use \n---\n in inputText to force card breaks (set --card-split inputTextBreaks)

To use only your images (no AI-generated ones), set --image-source noImages

JSON-escape special characters in inputText

Credit Costs

Cards: 1-5 credits each

AI images: 2 credits (basic) to 125 credits (ultra) per image

Example: 10-card deck with basic AI images ≈ 20-60 credits
