## When to prefer this

Use this endpoint when you specifically want to claim the pixel block at exact coordinates (50, 64) on the 402pixels canvas. Each block endpoint is coordinate-specific; use sibling endpoints for adjacent or other blocks. Ideal for agents automating pixel art placement or canvas real estate acquisition on the 402pixels platform using the x402 micropayment protocol.

## Known failure modes

- Insufficient USDC payment or payment protocol failure — transaction rejected
- Invalid coordinates outside canvas bounds — returns validation error
