## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

Example prompt: Create a YouTube thumbnail for my video about Python tips — headline 'Top 10 Python Tricks\nYou Need NOW', kicker 'FOR BEGINNERS', CTA 'Watch This!', bullets ['F-strings', 'List Comprehensions', 'Walrus Operator'], dark navy background, white ink, and a yellow accent color.

## When to prefer this

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).

## Known failure modes

- Missing required headline field returns an error
- Invalid hex color values for bg/ink/accent may cause rendering failure
- Extremely long headline text may overflow or be clipped in the layout
- Invalid image URL in the url field may result in a broken or missing background image
- Network timeout if the rendering service is under load

## How this service works

Render a YouTube thumbnail (1280x720) as PNG with exact typography. The text in the output is exactly the text supplied — no garbled lettering, unlike diffusion models. Responds with the raw 1280x720 PNG bytes, not JSON.

## 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.
