POST/v1/generateworkflow: motion_style_post-v1

One endpoint serves every workflow — this page documents motion_style_post-v1, the current version. Credits are debited at submission (1 cr/s standard, 1 cr/s pro); a failed generation is refunded automatically. Earlier versions of this endpoint, if any, keep being served under their own names.

Parameter	Value for this workflow
workflow	"motion_style_post-v1" required
picture_1	Photo — one public HTTPS URL.required
fields.bubble	Bubble. Defaults to “Fresh threads”.
fields.headline	Headline. Defaults to “SIMPLE WAYS TO”.
fields.highlight	Highlight. Defaults to “STYLE”.
fields.highlight_color	Highlight colour. Defaults to “#2F7BFF”.
fields.subline	Line. Defaults to “Build better outfits with simple choices.”.
fields.frame_color	Frame. Defaults to “#FFD60A”.
duration	10 (seconds)
tier	"standard" (1 cr/s), "pro" (1 cr/s)
webhook_url	Optional — we POST the outcome here when the generation settles. Without it, poll the URL returned in the response until the status settles.
