## 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-generate-mascot-ef25d96a -d '<json body>'
```

Example prompt: Generate a mascot for my tech startup called ByteBlast — make it a friendly robot holding a lightning bolt, use seed 42 so I can reproduce it later.

## When to prefer this

Choose this endpoint when you need a quick, cheap ($0.012 USDC), no-signup mascot image generated from a text description, especially when reproducibility via seed is important. Prefer this over larger cloud image generation APIs when cost-per-call and crypto payment (x402) are preferred, or when no API key registration is desired.

## Known failure modes

- Description too short (minLength 1) or too long (maxLength 300) — returns validation error
- Invalid seed type (non-integer) — returns schema validation error
- Model unavailable or server error — returns 5xx response
- Payment not provided or insufficient — returns 402 Payment Required
- Empty or nonsensical description may produce poor or abstract mascot output

## 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 a generated mascot image based on the provided description and optional seed. The image is created by a self-hosted AI image generation model. The seed allows reproducible outputs — using the same seed and description will yield the same mascot.
