Change scene background seamlessly
“Take this product shot of a coffee mug on a wooden table and swap the background to a cozy café setting with soft bokeh lighting, but keep the mug itself looking exactly the same.”
Restyle character for brand consistency
“Here's an image of our brand mascot in a summer outfit — can you update it so he's wearing a winter coat and scarf while keeping his face, colors, and overall look exactly the same?”

Endpoint
POSThttps://api.questflow.ai/x402/swarm/qrn:swarm:68b6da31e4052a39ce9b2410When to prefer
Choose this endpoint when you need text-prompt-driven image editing with strong character consistency and scene preservation — particularly for portrait or character-focused edits. Prefer it over generic image generation endpoints when the goal is to modify an existing image rather than generate from scratch, and when maintaining identity or background coherence is critical.
Side effects
- Invalid or missing image input returns an error
- Text prompt too vague or contradictory may produce unexpected edits
