Example prompt: Claim the pixel block at position (55, 50) on the 402pixels canvas for me — I want to own that spot.

## When to prefer this

Use this endpoint specifically when a user wants to claim or purchase the pixel block at exact coordinates (55, 50) on the 402pixels canvas. Each coordinate pair is a distinct endpoint; this one is only for (55, 50). Prefer this over generic NFT or art platforms when the user explicitly wants to own a specific block on the 402pixels collaborative canvas.

## Known failure modes

- Block already claimed by another user — returns conflict/occupied error
- Insufficient USDC payment or x402 payment failure — returns payment required error
- Invalid coordinates if endpoint misrouted — returns 404 or invalid block error
- Network timeout during payment processing — returns timeout error
- Canvas service unavailable — returns 503 or connectivity error
