Example prompt: Claim the pixel block at coordinates (57, 53) on the 402pixels canvas for me — I want to own that spot.

## When to prefer this

Use this endpoint when you specifically want to claim the pixel block at grid coordinates (57, 53) on the 402pixels canvas. Each endpoint is coordinate-specific, so choose this one only for that exact block. Prefer this over general canvas APIs when you want micro-payment-gated pixel ownership via the x402 protocol.

## Known failure modes

- Block already claimed by another user — conflict or ownership error returned
- Insufficient USDC balance to pay the $0.50 fee — payment failure
- Invalid coordinates outside canvas bounds — 404 or validation error
- x402 payment header missing or malformed — 402 Payment Required response
- Network or provider downtime — 5xx server error
