Example prompt: Claim pixel block at coordinates (57, 61) on the 402pixels canvas for me — I want to own that spot.

## When to prefer this

Use this endpoint specifically when a user wants to claim the pixel block at exact coordinates (57, 61) on the 402pixels canvas and is willing to pay $0.5 USDC via the x402 payment protocol. Each coordinate pair has its own endpoint on this service, so use the sibling endpoints for different block positions.

## Known failure modes

- Block already claimed by another user — returns conflict/taken error
- Insufficient USDC payment — x402 payment of $0.5 not fulfilled
- Invalid coordinates — if coordinates fall outside canvas bounds
- Network or payment protocol failure — x402 handshake fails
- Double-spend or payment replay — duplicate claim attempt rejected

## How this service works
