## 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 relaystation-og-image-generator-13f6f286 -d '<json body>'
```

Example prompt: Generate an OG card PNG for my article titled 'The Future of AI Agents' using a dark navy background with white text and my brand accent color #FF6B35.

## When to prefer this

Choose this endpoint when you need a programmatic, pay-per-call OG/social card image generated on demand without managing a headless browser or design template infrastructure. Ideal for dynamic content pipelines — blog posts, product pages, newsletters — where each link needs a unique branded preview PNG. Priced at $0.0005/call (1¢ minimum via x402), it suits high-volume or automated workflows where spinning up a custom image rendering service is not cost-effective.

## Known failure modes

- Missing required title field returns a 400 error
- Invalid or unreachable logo/image URL causes rendering failure
- Unsupported color format (e.g. invalid hex) may cause default fallback or error
- Payment insufficient (below 1¢ x402 minimum) results in 402 Payment Required
- Oversized text titles may be truncated or overflow the card layout

## How this service works

$0.0005/call. Render social/OG card PNGs — titles, colors, branding — for links that get clicked. 1¢ x402 min; remainder auto-credits — relaystation.ai/penny

## Output

A PNG image file (binary or URL) representing the rendered Open Graph / social card, sized for standard link preview dimensions, incorporating the supplied title, colors, and branding elements.
