# Nano Banana — Gemini Image Generation (RAEN x402)

> Pay $0.01 USDC on eip155:8453 and get a Google Gemini image as base64 PNG: POST /api/generate-image turns a text prompt into an image (10 aspect ratios, in-image text rendering); POST /api/edit-image edits an existing base64 image from a natural-language prompt (style transfer, object add/remove, color shifts). Pay per call via x402 — no API keys, no subscription. Free surfaces: GET /sample (exact output shape), GET /openapi.json, GET /pricing.md, GET /llms.txt, GET /about, GET /health, GET /.well-known/x402.json.
