Remove Background API

Cut the subject out cleanly: transparent or plain background, e-commerce-ready.

POST/v1/generateworkflow: remove_background-v1

One endpoint serves every workflow — this page documents remove_background-v1, the current version. Credits are debited at submission (0.3 cr standard, 1 cr 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	"remove_background-v1" required
source_image	Image to cut out — one public HTTPS URL.required
ratio	auto
tier	"standard" (0.3 cr) or "pro" (1 cr)
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.

Example request

curl -X POST https://thenewblack.ai/api/v1/generate \
  -H "Authorization: Bearer tnb_live_XXXXXXXXXXXX" \
  -H "Content-Type: application/json" \
  -d '{
    "workflow": "remove_background-v1",
    "source_image": "https://example.com/image.jpg",
    "ratio": "auto",
    "tier": "standard"
  }'

// 202 Accepted
{
  "generation_id": "3f1c9a6e-...",
  "status": "running",
  "poll": "/api/v1/generations/3f1c9a6e-..."
}

Example response

Poll /v1/generations/{id} (or receive the webhook) until the generation settles:

// 200 OK
{
  "generation_id": "3f1c9a6e-...",
  "workflow": "remove_background",
  "status": "succeeded",
  "result": {
    "type": "image",
    "url": "https://.../result.webp",
    "thumbnail": "https://.../thumb.webp"
  }
}
