Example prompt: Claim the pixel block at position (50, 56) on the 402pixels canvas for me — I want to own that specific spot.

## When to prefer this

Use this endpoint when a user specifically wants to claim and own the pixel block at canvas coordinates (50, 56) on the 402pixels platform. Each block endpoint is unique to its coordinates, so use this only for the (50, 56) position specifically.

## Known failure modes

- Block already claimed by another user — returns conflict or ownership error
- Insufficient USDC payment — x402 payment protocol rejects transaction
- Invalid or missing payment header — returns 402 Payment Required
- Network or API timeout — no confirmation received
- Coordinates out of bounds — though for this endpoint coordinates are fixed at (50,56)
