Remove an image's background (transparent PNG)
Supprime l’arrière-plan d’une image source, produisant un PNG transparent. L’appel renvoie 202 Accepted avec un id de job ; interroge GET /images/background-removals/{id} pour le résultat. L’image prend exactement un de image_id, url ou base64 + mime_type. Il n’y a aucun paramètre de modèle — v1 utilise le modèle de suppression d’arrière-plan par défaut. Requiert le scope images.transform.

Exemple : une source par mode

Le chemin normal (facturé) renvoie un job pending :
202 Accepted
Coût = 1 credit sur un miss ; 0 sur un hit de cache. Quand la source est un image_id que tu possèdes et qu’un résultat avec arrière-plan supprimé existe déjà pour lui, la soumission renvoie immédiatement 202 avec status: "completed" et estimated_credits: 0 — aucun nouveau job n’est mis en file et le plafond de concurrence de ton organisation n’est pas consommé. Tout autre cas (une source https url/base64 ou un image_id possédé sans résultat prêt) est le chemin facturé normal ci-dessus.
202 Accepted (hit de cache)

POST /images/background-removals body (SAM-820 / S8.8 — ADR §7, §8, §10).

Remove the background from ONE source image, producing a transparent PNG. The source is exactly one of image_id (an image in your organization's context), an https url, or base64+mime_type. There is NO model parameter — v1 uses the default background-removal model.

Cost = 1 credit on a miss; 0 on a cache HIT. When the source is an image_id you own and a background-removed result already exists for it, the submit returns 202 with status: "completed" and estimated_credits: 0 immediately (no new job is queued and the org's concurrency cap is not consumed). Every other case (an https url/base64 source, or an owned image_id with no ready result) is the normal charged path: 202 with status: "pending" and estimated_credits: 1.

requis

The source image: exactly one of image_id, an https url, or base64+mime_type.

webhook_url
string | null

Optional https webhook notified once on terminal status (signed per the webhook signature scheme; see the webhooks docs). On a cache hit the completed event fires immediately.

Exemple:

"https://example.com/webhooks/samsa"

Réponse

Successful Response

Shared 202 body for the transform-op submits (SAM-813 / S8 wave).

Every POST /images/<op> returns the async job handle {id, status, estimated_credits}. The initial status is pending (the job is queued), with ONE exception: background-removals and vectorizations answer an owned-image_id cache hit (a ready result already exists for that image) with status: "completed" and estimated_credits: 0 — no new job is queued, the completed webhook event is emitted immediately for a supplied webhook_url, and the result is already available from the op's GET .../{id} endpoint. The other transform ops (img2img, variations, resizes, upscales) always start pending.

id
string<uuid>
requis

The job id — poll the op's GET .../{id} endpoint.

status
enum<string>
requis

Initial status: pending (job queued — enter the polling flow), or completed with estimated_credits: 0 when background-removals / vectorizations serve an owned-image cache hit (the result is immediately available).
