402pixels Block Claim (52, 61)

Use this endpoint when you specifically want to claim pixel block (52, 61) on the 402pixels canvas. Each coordinate pair is a unique endpoint, so use the sibling endpoints for different coordinates. Prefer this over alternatives when participating in the 402pixels collaborative canvas project and targeting this exact grid position.

• Block already claimed by another user — returns conflict/taken error
• Insufficient USDC payment — returns payment required or underpayment error
• Invalid coordinates outside canvas bounds — returns 400 bad request
• Payment processing failure via x402 protocol — returns payment error
• Network timeout during payment settlement
