Use this endpoint specifically when a user wants to claim or own the pixel block at the exact coordinates (56, 51) on the 402pixels shared canvas. Each coordinate pair has its own endpoint, so this is the only endpoint to use for that specific position.

## Known failure modes

- Invalid coordinates if endpoint path is altered
