402pixels Block Claim (55, 57)

Use this endpoint when you specifically want to claim pixel block (55, 57) on the 402pixels canvas. Each coordinate pair is a distinct endpoint, so choose this one only when targeting that exact grid position. Prefer this over manual canvas interaction when automating pixel purchases or building agents that participate in collaborative pixel art canvases.

• Block already claimed by another user — returns conflict or 409-equivalent error
• Insufficient USDC payment or payment failure — returns payment required error
• Invalid coordinates if endpoint miscalled — returns 404 or bad request
• Network or API downtime — returns 5xx server error
