Image generation

POST/v1/images/generations10 per image · +2 with store: true

Returns the image inline as base64 (b64_json), or a URL when the engine answers with one. Outputs are not retained on our side — unless you ask us to keep them:

Set store: true to persist the render to the eroq Store in the same call: the response answers with a durable CDN URL instead of base64, plus a stored block. The Store's rate (2 credits / started 10MB — one block for any 1024×1024 image) is charged on top and itemized in your ledger.

Image One is a diffusion engine: it responds to negative_prompt and cfg_scale, and reads comma-separated tag prompts as well as prose. It is NSFW-capable: mature imagery of adult characters renders within the acceptable-use policy; prompts outside it return content_blocked and are not charged.

Rendering takes a few seconds; the request holds until the image is ready.
