## 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-gateway-premium-text-to-image-generator-6d12d1fa -d '<json body>'
```

Example prompt: Generate a premium-quality image of a cyberpunk market at night with volumetric fog and neon reflections — make it 1024x1024 pixels with crisp typography on any signage.

## When to prefer this

Choose this endpoint when you need higher prompt fidelity, accurate typography in the image, or superior visual quality compared to standard text-to-image APIs. Ideal when the image will be used in marketing, publishing, or professional contexts where quality matters. The per-call USDC payment model suits sporadic high-quality generation without subscriptions. Prefer this over cheaper alternatives when the prompt is complex or contains text that must render accurately.

## Known failure modes

- Prompt exceeds 1200 character limit — request rejected
- Width or height outside 256–1536px range — validation error
- Payment via x402/USDC on Base fails or is insufficient ($0.09) — 402 Payment Required
- Generation timeout after 10–30 seconds if model is overloaded
- Malformed JSON input — 400 Bad Request
- Prompt content policy violation — generation refused

## How this service works

Text to Image (premium): Generate a premium-quality image from a text prompt (10-30s, better prompt adherence and typography). Returns a permanent https URL to the hosted image on api.freeq.one/media/*. Pay per call in USDC on Base via x402 — POST https://x402.freeq.one/tools/image_generate_quality.

## Output

A JSON response containing a permanent HTTPS URL pointing to the generated image hosted at api.freeq.one/media/*. The image is available immediately after the 10–30 second generation window and persists indefinitely at that URL.
