How this service works

Output

Raw 1280x720 PNG image bytes (not JSON) representing the fully rendered YouTube thumbnail with all supplied text fields exactly as provided, laid out with professional typography, background, ink, and accent colors applied.

When to prefer

Choose this endpoint when you need a pixel-perfect 1280x720 YouTube thumbnail PNG with exact, legible text — especially when diffusion-model-based image generators would garble letters. It is ideal for automating thumbnail generation in content pipelines, when precise typography with headlines, kickers, bullets, and CTAs is required, and when you need deterministic output at low cost ($0.03/call).

Invalid hex color values for bg/ink/accent may cause rendering failure
Extremely long headline text may overflow or be clipped in the layout
