## 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 api-402pixels-com-dfeb46f8 -d '<json body>'
```

Example prompt: Claim the pixel block at position (0, 0) — the origin corner — on the 402pixels canvas for me and pay the $0.75 USDC fee.

## When to prefer this

Use this endpoint specifically when the user wants to claim the pixel block at coordinates (0, 0) on the 402pixels canvas. Choose this over other sibling endpoints only when the origin/top-left block is the target. Requires x402 USDC payment capability.

## Known failure modes

- Block already claimed — another user has already claimed (0,0) and it is no longer available
- Payment failure — insufficient USDC balance or x402 payment protocol error
- Invalid coordinates — coordinates out of bounds or malformed request body
- Network timeout — API unreachable or slow to respond
- Duplicate claim attempt — caller tries to re-claim a block they already own

## How this service works

## Output
