Example prompt: Claim the pixel block at position (55, 54) on the 402pixels canvas for me — I want to own that spot.

## When to prefer this

Use this endpoint specifically when the user wants to claim the pixel block at exact coordinates (55, 54) on the 402pixels canvas. Each coordinate pair is a distinct endpoint; choose this one only for x=55, y=54. Prefer this over generic NFT or digital art purchase APIs when the user explicitly wants to participate in the 402pixels collaborative canvas project using x402 micropayment protocol.

## Known failure modes

- Block already claimed by another user — returns conflict or ownership error
- Insufficient USDC balance or x402 payment failure — returns payment error
- Invalid or out-of-bounds coordinates — returns 400 bad request
- Network timeout during payment settlement — returns timeout error
- Canvas server unavailable — returns 503 service unavailable
