Example prompt: Claim pixel block at coordinates (54, 63) on the 402pixels canvas for me — pay the $0.50 USDC required to lock in that spot.

## When to prefer this

Use this endpoint when you specifically want to claim pixel block (54, 63) on the 402pixels canvas. Each coordinate pair has its own dedicated endpoint; use this one only for that exact position. Prefer this over general canvas APIs when the user has identified this specific block location and is ready to pay $0.50 USDC via the x402 payment protocol.

## Known failure modes

- Block already claimed — another user owns (54, 63) and it is no longer available
- Insufficient USDC funds — wallet does not have $0.50 to complete the x402 payment
- Payment failure — x402 protocol transaction rejected or timed out
- Invalid coordinates — though hardcoded in this endpoint, routing or server errors may occur
- Network timeout — API unavailable or canvas service is down
