Segmind PixelFlow Workflow API
Call a published PixelFlow workflow over REST. Submit to POST /workflows/v2/{slug} with the key names given to the workflow's input nodes, poll the status URL, and fetch the result — the same async contract and the same x-api-key header as model inference. The result's output field is a JSON-stringified array of {keyname, value} pairs, one per named output node.
