Sky Replacement
Replace overcast or dull skies with the sky the listing deserves. Pick the mood — crisp blue, soft clouds, dramatic, or sunset — and reflections and lighting stay photorealistic.

Ordering
Submit an order with POST /v1/orders — or one call of SDK. The snippets below are complete: upload, order, live progress, download.
/v1/ordersimport { BkbnClient } from '@bkbnlab/api'
const bkbn = new BkbnClient() // reads BKBNLAB_API_KEY
const photo = await bkbn.upload('living-room.jpg')
const order = await bkbn.order({
inputs: [photo],
sky: 'dramatic',
})
const result = await order.wait({
onProgress: (p) => console.log(p.stage, p.percent),
})
await result.save('result.jpg')Options
Options ride the order body next to inputs. Everything is optional — an order with no options runs the base develop.
| Option | Type | Description |
|---|---|---|
sky | boolean | Turn sky replacement on. Default: false. |
sky_style | enum | The sky mood to composite. Options: clear, soft_clouds, dramatic, sunset. Default: soft_clouds. |
