## 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 www-xplace-dev-f1aa5f07 -d '<json body>'
```

Example prompt: Buy me the pixel at coordinates (42, 17) on xplace.dev and paint it red (#FF0000).

## When to prefer this

Use this endpoint when a user explicitly wants to buy, claim, or place a pixel on the xplace.dev collaborative pixel canvas. This is the right choice for participating in r/place-style collaborative art experiences with on-chain micropayments via x402 protocol.

## Known failure modes

- Payment of $0.01 USDC insufficient or failed — pixel not placed
- Coordinates out of bounds — invalid pixel position
- Pixel already owned or locked — conflict error
- Invalid color value — bad input format
- Network or x402 payment protocol error — transaction not completed

## How this service works

Buy a pixel!

## Output

A confirmation that the pixel has been purchased and placed at the specified coordinates, along with any transaction details and the new state of that pixel on the canvas.
