Nano Banana 2 API Guide: When You Need an API vs the Browser

“Nano Banana 2 API” searches usually mean one of two jobs: wire generation into a product, or escape manual clicking. I’ve done both. This guide is about choosing the right interface, not inventing fake endpoints.

TL;DR

Need	Use
Campaign assets this week	Browser on NanoBananaTool
User-facing app generation	Real API integration
Prompt R&D	Browser first
Batch pipelines	API / workers

What people mean by “API guide”

1. Auth + request/response shapes
2. Async jobs and webhooks
3. Rate limits / retries
4. Storing outputs

If you don’t have eng time for (2)–(4), an API will feel slower than a good web UI.

Browser-first path (my default for marketing)

For most DTC and creator work I stay in /generate: upload refs, iterate prompts, download. No queue plumbing.

When an API is worth it

• You generate inside your SaaS
• You need deterministic pipelines
• Compliance requires logged requests

For video-side API thinking, see /blog/seedance-2-0-api-guide.

Design checklist before you integrate

• Idempotent job IDs
• Clear failure reasons to the UI
• Timeout + retry policy
• Content moderation expectations
• Cost caps per user

NanoBananaTool angle

If your bottleneck is creative iteration—not software distribution—ship with the browser first.
