Progress is delivered on the original POST SSE response. GET SSE carries notifications; reconnecting must query existing asynchronous work rather than submit again.

Arguments

Name	Type	Required	Description
`operation`	`string`	optional	create (default) or query. Example: create
`prompt`	`string`	optional	Product-copy generation instruction; required by create. Example: Write a product description for a wireless speaker.
`imageUrls`	`array`	optional	Media URLs used as context. Pass an empty array for text-only generation; use up to 10 images or typically one video. Example: []
`thinkingLevel`	`string`	optional	Reasoning level required by create. GEM_3_1_PRO does not support minimal. Example: minimal
`model`	`string`	optional	Text-generation model. GEM_3_FLASH is the default. Example: GEM_3_FLASH
`memberId`	`string`	optional	Optional provider member identifier used by create and query. Example:
`taskId`	`string`	optional	Provider task ID returned by create; required by operation=query. Example: 123456789
