## 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 fastapi-online-anime-image-generator-6f462ae5 -d '<json body>'
```

Example prompt: Generate an anime image of a silver-haired female warrior standing in a moonlit forest, wearing traditional Japanese armor — use seed 42 so I can reproduce it later.

## When to prefer this

Choose this endpoint when you need anime-specific image generation rather than photorealistic or generic art styles. It is ideal for agents that need reproducible outputs (via seed), want pay-per-call pricing with no signup using crypto, and require a dedicated anime diffusion model rather than a general-purpose image generator like DALL-E or Stable Diffusion with generic settings.

## Known failure modes

- Description too short (below 1 character) or too long (above 300 characters) — validation error
- Invalid seed type (non-integer) — schema validation failure
- Model timeout or inference failure on the self-hosted backend — 500 error
- Payment not received or insufficient USDC — 402 Payment Required
- Missing required description field — 422 Unprocessable Entity

## How this service works

Chat, embeddings, OCR, speech-to-text, image editing, image understanding (captioning/Q&amp;A), text-to-speech, translation, writing tools, classification tools, developer tools, local utilities, format/checksum validators, encoding &amp; crypto utilities, date/time calculators, geo/coordinate math, math &amp; finance calculators, novelty tools, and business/social writing generators — 179 endpoints in all, across multiple specialized self-hosted models. Pay per call with crypto — no signup — or get an API key.

## Output

Returns an anime-style image generated from the provided text description. The seed parameter enables deterministic generation so the same prompt+seed combination produces consistent results. The image is typically returned as binary image data or a URL pointing to the generated artwork.
