Nano Banana 2 API Limits: Resolution, Inputs and Request Boundaries

APIMART serves Nano Banana 2 through POST /v1/images/generations. The current documentation describes an asynchronous submit-and-poll workflow. The boundaries below were checked on September 2, 2026.

Verified boundaries

• The current product surface exposes the exact route ID nano-banana-2-ext.
• The current surface exposes output choices through 4K.
• It exposes text generation, image editing and a reference-image input.
• The surface also exposes content moderation, official-channel fallback and Google Search controls.
• The reviewed product page says result image links remain available for 72 hours, so copy outputs promptly.
• The product surface does not by itself establish an exact maximum output count or reference-image count; validate the live route before batching.

Minimal integration rule

Send the documented model ID, required prompt and only compatible optional inputs. Persist the returned task_id, implement bounded polling and backoff, and keep 400, 401, 402, 429 and 5xx responses out of completed-output metrics.

FAQ

Which endpoint serves Nano Banana 2?

Use POST /v1/images/generations with the documented model ID and Bearer authentication.

Is processing synchronous?

No. A successful submission returns a task ID that must be polled for completion.

What is the first production safeguard?

Validate model ID, quantity or duration, resolution and input combinations before submission.

Can documented limits change?

Yes. Treat the live endpoint documentation as the source of truth and version your request profile.

Should a submitted task be counted as completed output?

No. Count success only after the task endpoint reports a completed result.
