About

nano-banana is the catalogue's straight image-gen endpoint. Pass a prompt and (optionally) an aspect ratio; get back a PNG hosted under /r/.

**When to use this vs poster-forge:** • Use nano-banana when you want full control over the prompt and just need the raw artwork. • Use poster-forge when you want orqis to plan a typographic layout (title, subtitle, event details) and composite real text over the generated background. nano-banana doesn't do text rendering reliably.

**Modes:** • **Managed** — set `GEMINI_API_KEY`. Buyers pay 15 credits per call (image-gen is the priciest tier). • **BYO key** — pass `apiKey` for the 1-credit routing fee; your Gemini account pays for the image. • **Mock** — neither set → returns an SVG-composited placeholder showing your prompt + a 'MOCK' badge.

Aspect ratios: 1:1 (1024x1024), 4:3, 3:4, 16:9, 9:16. Prompt cap: 4,000 chars.
