## 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 delx-pro-image-flux-1-1-pro-for-agents-61548d93 -d '<json body>'
```

Example prompt: Generate a high-quality FLUX 1.1 Pro hero image of a minimalist coffee shop interior with warm lighting and wooden furniture, in 16:9 landscape format using the balanced quality profile — I need something polished enough to ship on a landing page.

## When to prefer this

Choose this endpoint when you need production-ready, brand-safe images with strong prompt adherence and fine detail — hero stills, campaign creatives, or product shots where the $0.01 draft quality is insufficient. Prefer this over the draft tier when the output will be customer-facing or shipped in a campaign. Ideal for agent workflows that require no API key, no subscription, and verifiable image integrity via SHA-256.

## Known failure modes

- Invalid or empty prompt returns a 400 validation error
- Unsupported model alias returns an enum validation error
- Aspect ratio not in allowed list returns a 400 error
- x402 payment failure or insufficient USDC balance blocks the request
- Prompt exceeds 2000 character limit returns a validation error
- Upstream Replicate model timeout or outage returns a 5xx error

## How this service works

Pro-grade FLUX 1.1 Pro images for agents at $0.06 USDC. Call when the $0.01 draft is not good enough to ship—hero stills, campaign creatives, product shots, and brand-facing assets with sharper detail and stronger prompt adherence. Public WebP URL + SHA-256 via x402 on Base; no API key, no subscription.

## Output

Returns a public WebP image URL (hosted, immediately accessible), a SHA-256 hash of the image for integrity verification, upstream model cost, and gross margin markup fields. Payment is processed via x402 on Base at $0.06 USDC per call with no API key or subscription required.
