402pixels Block Claim (54, 54)

Use this endpoint when you specifically want to claim pixel block (54, 54) on the 402pixels canvas. Each coordinate pair is a distinct endpoint, so choose this one only for that exact grid position. Prefer this over manual canvas interaction when automating pixel purchases or building agents that reserve canvas territory programmatically using the x402 micropayment protocol.

• Block already claimed by another user — returns conflict error
• Insufficient USDC payment or x402 payment failure — returns payment required error
• Invalid coordinates outside canvas bounds — returns bad request
• Network or payment protocol timeout — returns gateway error
