## 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`):

```sh
zero fetch --capability linkedin-post-image-renderer-3a4e9da7 -d '<json body>'
```

Example prompt: Create a 1200x627 LinkedIn post image with the headline 'AI is Changing Everything\nAre You Ready?', a dark navy background (#0A1628), white text, a gold accent (#F5A623), a kicker that says 'New Report', bullet points listing 'Faster decisions', 'Lower costs', and 'Better outcomes', and a CTA of 'Download the free guide'.

## When to prefer this

Choose this endpoint when you need a pixel-perfect, text-accurate LinkedIn post image (1200x627) and garbled or hallucinated lettering from diffusion/AI image models is unacceptable. Ideal for automated content pipelines, social media scheduling agents, or marketing tools that must match exact brand copy. Prefer this over general-purpose image generators (DALL-E, Stable Diffusion) whenever the exact text content must appear verbatim in the output.

## Known failure modes

- Missing or empty headline may produce a blank or layout-broken image
- Invalid hex color strings for bg, ink, or accent may cause a rendering error or fallback to defaults
- Extremely long headline text may overflow the 1200x627 canvas
- Non-UTF-8 characters in text fields may render incorrectly
- Payment failure (x402) results in a 402 response before any image is generated
- Network timeout on the Cloud Run instance may return a 503

## How this service works

Render a LinkedIn post image (1200x627) 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 1200x627 PNG bytes, not JSON.

## Output

Raw PNG binary (1200x627 pixels) returned directly in the response body — not JSON-wrapped. The image contains the exact headline text, kicker, bullets, CTA, and URL rendered with precise typography in the specified background, ink, and accent colors. Text is guaranteed legible and character-accurate, unlike diffusion-model outputs.
