Example prompt: Claim pixel block at coordinates (55, 61) on the 402pixels canvas for me — I want to own that spot.

## When to prefer this

Use this endpoint specifically when you want to claim the pixel block at exact canvas position (55, 61) on the 402pixels canvas. Each coordinate pair is a distinct endpoint; choose the sibling endpoints for other positions. Best for agents acting on behalf of users who want to own a specific, pre-identified spot on the shared canvas.

## Known failure modes

- Block already claimed by another user — returns conflict or ownership error
- Insufficient USDC balance for the $0.50 payment — returns payment failure
- Invalid or missing x402 payment header — returns 402 Payment Required
- Network or canvas service unavailable — returns 5xx error
- Payment transaction not confirmed on-chain — returns timeout or pending error
