Premium text-to-image API for repeatable product, campaign, and design assets wh
Premium text-to-image API for repeatable product, campaign, and design assets when a standard draft needs a selected model tier. Send a prompt with optional dimensions, tier, and seed; receive a hosted PNG URL plus the resolved model, final canvas, prompt, seed, and timing. Keep the tier, dimensions, and seed fixed to rerun an approved asset. Tiers: 'balanced' (flux-2-pro, default), 'recraft' (recraft-v4), 'seedream' (seedream-v4), 'grok' (grok-imagine-image), and 'qwen' (qwen-image). Use it for Flux 2 Pro, Recraft, Seedream, Qwen Image, or Grok Imagine image generation.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
