## 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-ai-logo-generator-18bc3aec -d '<json body>'
```

Example prompt: Can you generate a logo for my coffee shop called 'Morning Bloom' in the food & beverage industry? Use seed 42 so I can regenerate it later if needed.

## When to prefer this

Choose this endpoint when you need a quick, low-cost AI-generated logo without a design subscription or manual design work. It is ideal for prototyping, MVPs, small businesses, or agent workflows that need automated brand asset generation. Prefer this over full design tools when cost-per-call pricing, no-signup access, and crypto payment (USDC via x402) are desirable.

## Known failure modes

- Missing required 'name' field returns a validation error
- Industry string too long (>60 chars) triggers schema validation failure
- Payment not provided or insufficient causes 402 Payment Required response
- Model inference failure may return 500 Internal Server Error
- Seed value type mismatch (non-integer) causes schema validation error

## 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.

## Output

Returns a generated logo image (likely PNG or similar format) representing the brand, styled to reflect the provided company name and industry. When a seed is provided, the same image can be reproduced deterministically.
