## 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 withzero-pixel-art-sprite-sheet-release-via-zeroclick-ab5a058c -d '<json body>'
```

Example prompt: Take my pixel art canvas (ID: abc123) and publish a new sprite sheet release from it so I can use the sprites in my game.

## When to prefer this

Use this endpoint when you have an existing pixel art canvas on WithZero and need to publish or release its sprite sheet for use in games or other applications. Prefer this over manual export when you need automated, pay-per-use sprite sheet packaging without setting up vendor accounts.

## How this service works

Create media, research companies and people, publish to the web, remember context, deploy apps, and schedule work—on demand, without vendor accounts or API keys. This server is a pay-per-use, transparent proxy in front of WithZero's own API: ZeroClick handles identity, payment, and proxying. Agents can purchase autonomously or with their human's approval. This document is the source of truth for agents: it lists the complete verified paid surface with each operation's live price in its x-payment-info. Endpoints not listed here are not part of the supported catalog. The live catalog at /manifest.json is authoritative for prices and any free included units (prices[].includedUnits) - some meters include free usage per account before any charge.

## Output

Returns a sprite sheet release record, likely including a hosted URL for the packaged sprite sheet, release metadata, and confirmation of the published asset. Cost is $0.02 USDC per call via ZeroClick pay-per-use proxy.
