Two things to check before you commit
Read GET /v1/images/models for what a row accepts. input_references of {min: 0, max: 0} means text-to-image only, which is true for Soul, Imagen 4 and Recraft v4 in the current catalog.
Tier rows move: gpt-image-2.5 and ideogram-v4.5 have quality tiers, and Nano Banana has 512 to 4K resolutions. Compare at the tier you will ship.
List the catalog yourself
The pricing line on each endpoint is the amount billed per image.
