Return the current MarkItUp credit balance and subscription status for the authenticated account. Use this before calling generation tools to verify the account has credits available.

Generate polished marketing-visual variations of a screenshot or image using the MarkItUp pipeline (Claude analyzes the image and writes copy; Gemini renders the visuals). Costs 1 credit. Provide the image either as a public URL (image_url) OR as a base64-encoded string (image_base64) — exactly one. Common template IDs: glassmorphic, clean_minimal, bold_marketing, dark_professional, documentation. Returns the generated images plus the marketing copy (headline, subhead) written by Claude.

Regenerate a single variation from a previous markitup_generate call with the same source image and template. Costs 1 credit if charge_credit=true. Pass back the source image (as URL or base64) AND the text analysis object returned in the previous generate's structuredContent.text — the regen uses the same headline/copy so visuals stay consistent. Use variation_index to choose which slot (0–2) to regenerate.

AI-outpaint an image to a larger canvas. Useful for converting a square asset to 16:9 or 9:16, or extending a tight crop. Costs 1 credit. Provide the source image as URL or base64, plus the target aspect ratio and pixel dimensions.

Remove the background from an image using Photoroom's HD AI background-removal service. Returns a transparent PNG. Costs 1 credit (free for active Pro/Power subscribers). Provide the source image as URL or base64.
