Example prompt: Claim pixel block at position (55, 63) on the 402pixels canvas for me — go ahead and pay the 0.50 USDC required to own that spot.

## When to prefer this

Use this endpoint when you specifically want to claim the pixel block at coordinates (55, 63) on the 402pixels canvas and are ready to pay $0.50 USDC via the x402 protocol. Each coordinate pair has its own dedicated endpoint, so this is the only way to claim exactly this block.

## Known failure modes

- Block already claimed — another user owns (55, 63), returns conflict or already-owned error
- Insufficient payment — USDC balance too low or x402 payment header missing/malformed
- Invalid coordinates — though (55, 63) is hardcoded in this endpoint, the server may still reject if out of canvas bounds
- Payment network error — blockchain or x402 facilitator unavailable
- Rate limiting — too many claim requests in a short window
