Rimuovi lo sfondo da una image sorgente, producendo un PNG trasparente. La chiamata restituisce 202 Accepted con un id del job; interroga GET /images/background-removals/{id} per il risultato. L’image prende esattamente uno tra image_id, url o base64 + mime_type. Non c’è alcun parametro di modello — v1 usa il modello di rimozione dello sfondo predefinito. Richiede lo scope images.transform.

Esempio: una sorgente per modalità

curl -X POST https://api.samsa.ai/public/v1/images/background-removals \
  -H "Authorization: Bearer $SAMSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "image": { "image_id": "123e4567-e89b-12d3-a456-426614174000" } }'

curl -X POST https://api.samsa.ai/public/v1/images/background-removals \
  -H "Authorization: Bearer $SAMSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "image": { "url": "https://cdn.example.com/photo.png" },
    "webhook_url": "https://example.com/webhooks/samsa"
  }'

curl -X POST https://api.samsa.ai/public/v1/images/background-removals \
  -H "Authorization: Bearer $SAMSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "image": { "base64": "iVBORw0KGgoAAAANSUhEUg...", "mime_type": "image/png" } }'

Il percorso normale (addebitato) restituisce un job pending:

202 Accepted

{
  "id": "f7a8b9c0-1d2e-4f3a-4b5c-6d7e8f9a0b1c",
  "status": "pending",
  "estimated_credits": 1
}

Costo = 1 credit su un miss; 0 su un cache hit. Quando la sorgente è un image_id che possiedi e per esso esiste già un risultato con lo sfondo rimosso, l’invio restituisce immediatamente 202 con status: "completed" e estimated_credits: 0 — nessun nuovo job viene messo in coda e il limite di concorrenza della tua organizzazione non viene consumato. Ogni altro caso (una sorgente https url/base64 o un image_id posseduto senza risultato pronto) è il normale percorso addebitato sopra.

202 Accepted (cache hit)

{
  "id": "f7a8b9c0-1d2e-4f3a-4b5c-6d7e8f9a0b1c",
  "status": "completed",
  "estimated_credits": 0
}

Errori

Stato	Codice	Quando
`402`	`insufficient_credits` / `insufficient_team_credits` / `insufficient_unallocated_credits`	Il saldo che questa credenziale può spendere è al di sotto del costo del job. Le organizzazioni con almeno un team attivo ricevono i codici legati ai team invece di `insufficient_credits` (eccetto le organizzazioni di sistema esenti dal budgeting per team). Un guasto operativo nella detrazione stessa può comunque restituire il generico `insufficient_credits`, qualunque sia il regime.
`402`	`subscription_inactive`	L’organizzazione non ha un abbonamento utilizzabile.
`403`	`missing_scope`	La chiave non ha lo scope `images.transform`.
`404`	`not_found`	L’`image_id` sorgente è sconosciuto o non appartiene al creatore della chiave — anche un’immagine creata da un altro membro della tua organizzazione è un `404`.

Organization API key as a bearer token: Authorization: Bearer samsa_sk_....

Corpo

application/json

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.

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

Show child attributes

webhook_url

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.

Risposta

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.

string<uuid>

obbligatorio

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

status

enum<string>

obbligatorio

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).

Opzioni disponibili:
