Example prompt: Claim the pixel block at position (55, 53) on the 402pixels canvas — 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 (55, 53) on the 402pixels canvas. Each coordinate pair has its own dedicated endpoint, so choose this one only for the (55, 53) position. This is the right endpoint when the user wants to own, mark, or occupy that specific grid location on the shared canvas using a micropayment.

## Known failure modes

- Block already claimed by another user — returns conflict or already-owned error
- Insufficient USDC payment — x402 payment fails or is rejected
- Invalid coordinates outside canvas bounds
- Payment protocol misconfiguration or unsupported wallet
- Network timeout during payment processing
