Portrait art with reference style guidance
“Generate a high-fidelity square portrait of a Renaissance-style noblewoman with golden jewellery and a velvet dress, and use these two reference images I'm providing to guide the lighting style and color palette.”

Endpoint
POSThttps://api.xona-agent.com/base-main/image/flux-2-maxWhen to prefer
Choose this endpoint when maximum image quality and fidelity are required — it uses Black Forest Labs' top-tier Flux 2 Max model, making it the best option for professional creative output, detailed concept art, or any use case where visual quality cannot be compromised. Prefer this over sibling image endpoints (e.g. Seedream-4.5, Nano Banana, xona designer) when you need the absolute best output and are willing to pay the premium per-call price of $0.08 USDC. Use the reference image feature when compositional or style consistency with existing visuals is important.
Side effects
- Missing or vague prompt may produce unexpected or low-quality output
- Invalid aspect ratio string returns a validation error
- Reference image URLs that are inaccessible or non-image URLs will fail or be ignored
- Payment failure (insufficient USDC or x402 protocol error) results in 402 Payment Required
- Rate limiting or model overload may cause timeout or 503 errors
- Prompt violates content policy and is rejected with a 400 or 422 error
