Fabric on Sketch API

Fill a technical sketch with a real fabric: the drawing keeps its lines, the fabric brings it to life.

POST/v1/generateworkflow: insert_fabric_on_sketch-v1

One endpoint serves every workflow — this page documents insert_fabric_on_sketch-v1, the current version. Credits are debited at submission (1 cr standard, 3 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	"insert_fabric_on_sketch-v1" required
sketch_image	Your sketch — one public HTTPS URL.required
fabric_image	Your fabric — one public HTTPS URL.required
ratio	auto
tier	"standard" (1 cr) or "pro" (3 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": "insert_fabric_on_sketch-v1",
    "sketch_image": "https://example.com/sketch.jpg",
    "fabric_image": "https://example.com/fabric.jpg",
    "ratio": "auto",
    "tier": "standard"
  }'

Example response

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

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

Results are stored for 48 hours — copy them to your own storage. Authentication, errors and webhooks are documented in the full API reference.
