402pixels Block Claim (54, 62)

Use this endpoint when you specifically want to claim the pixel block at coordinates (54, 62) on the 402pixels canvas. Each pixel block is a unique coordinate, so this endpoint is only relevant for that exact position. If targeting a different block, use the corresponding coordinate-specific endpoint.

• Block already claimed by another user — returns conflict or ownership error
• Insufficient USDC balance or x402 payment failure — transaction rejected
• Invalid coordinates outside canvas bounds — 400 error
• Network timeout during payment processing — unclear ownership state
• Payment accepted but state not updated — may require retry or verification
