## When to prefer this

Choose this endpoint when you need pay-per-call image generation billed in USDC on Base via the x402 protocol, with no subscription or API key signup required for bots. At $0.02 per image it is cost-effective for low-to-medium volume generation. Prefer it over alternatives when your agent workflow already handles x402 micropayments on Base, or when you want GPU-backed fast inference without managing a standing account.

## Known failure modes

- Invalid or missing prompt — returns 400 Bad Request
- Width or height values outside supported range — returns 400 with dimension error
- Server-side GPU timeout or overload — returns 503 Service Unavailable
