## 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-2f9a282f -d '<json body>'

Example prompt: Claim block at position (51, 66) on the 402pixels canvas — I want to own that spot and I'm ready to pay the 0.50 USDC fee.

## When to prefer this

Use this endpoint when an agent or user explicitly wants to claim the specific pixel block at coordinates (51, 66) on the 402pixels canvas. Each block endpoint is coordinate-specific, so select the sibling endpoint matching the desired (x, y) position. Prefer this over generic NFT or pixel art platforms when the goal is to own a precise block on the 402pixels shared canvas using the x402 micropayment protocol.

## Known failure modes

- Block already claimed by another user — returns conflict or already-owned error
- Insufficient USDC balance or invalid x402 payment header — returns payment failure
- Invalid coordinates (out of canvas bounds) — returns 400 bad request
- Network or service downtime — returns 5xx error
- Payment protocol mismatch or unsupported wallet — returns payment error
