Nano Banana is a family of AI image generation models. Available in three variants (Base, Pro, and 2), they offer different trade-offs between speed, quality, and cost. JourneyAPI provides programmatic access to all three through a single REST API.
Base for rapid prototyping and high-volume generation (1 credit, ~3s). Pro for marketing and social media visuals (2 credits, ~5s). Nano Banana 2 for professional-grade output (2 credits, ~4s). All three use the same API — just change the model parameter.
Yes. All variants accept reference images via the images[] parameter. Nano Banana 2 additionally supports reference blending — combining style and content references for more controlled output.
Base costs 1 credit per generation (~$0.015 on Starter plan). Pro and Nano Banana 2 cost 2 credits (~$0.03). You only pay for successful generations — failed requests are free.
All variants support 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, and 2:3. Pass the aspect_ratio parameter with your request.
Asynchronous. Submit a request, receive a task_id immediately. Results delivered via webhook or polling. Consistent with all other JourneyAPI models.
Generated images can generally be used for commercial purposes. You are responsible for ensuring compliance with all applicable laws and the underlying model provider's terms of service.
