## 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 x402-agentutility-ai-event-poster-image-generator-0eddb395 -d '<json body>'
```

Example prompt: Generate a portrait-format event poster for our annual AI Summit — show a futuristic cityscape at night with glowing neon lights and a bold stage — use the 'creative' tier at 768×1024 pixels.

## When to prefer this

Choose this endpoint when you need original, custom SFW event imagery (posters, banners, campaign backgrounds) without relying on stock photo libraries. It is ideal for autonomous agents building event promotion pipelines or conference marketing workflows, and supports multiple model tiers (fast, creative, anime, sd35) to balance speed against stylistic control.

## Known failure modes

- Prompt exceeds 2000 characters — request rejected
- Width or height outside 256–1024 range — snapped or rejected
- Invalid model name provided — returns error
- Payment not provided or insufficient USDC — x402 payment required response
- Model tier enum value unrecognized — defaults or errors
- Prompt violates SFW content policy — generation refused or filtered

## How this service works

Generates SFW event artwork, launch posters, and campaign backgrounds without relying on stock art. Same fast image-generate backend. Use it as an event poster image generator API, conference visual tool, or meetup campaign image source.

## Output

Returns a JSON object containing the hosted image URL (on fal.media CDN), the model used for generation, and the output image dimensions (width and height in pixels).
