Agrandir une image
Soumets un job d’upscale — une image source vers une résolution cible supérieure — et récupère un id de job.
image source vers une target_resolution supérieure avec l’un des
quatre modèles. L’appel renvoie 202 Accepted avec un id de job ; interroge
GET /images/upscales/{id} pour le
résultat. L’image prend exactement un de image_id, url ou
base64 + mime_type. Requiert le scope images.transform.
Exemple : une source par mode
Exemple : magnific-creative avec options
202 est le handle de job asynchrone :
model est crystal (défaut), seedvr, magnific-creative ou
magnific-precision. target_resolution est requis et tiré d’un ensemble
fermé : 2K, 4K, 6K, 8K, 10K, 12K, 14K, 16K, 20K, 24K, 28K,
32K, 38K. Les classes au-dessus de 16K ne sont valides que pour crystal.
Les plafonds de facteur et d’aire par modèle sont validés avant toute
facturation — une requête au-dessus du plafond est un 422, jamais un job facturé.options sont par modèle, typées et validées strictement : fournis
magnific_creative pour le modèle magnific-creative ou magnific_precision pour
magnific-precision. seedvr et crystal ne prennent aucune option — fournir
options pour eux est un 422. Les clés inconnues ou les valeurs hors plage sont

Le coût est le palier de résolution (2K:5, 4K:10, 6K:20, 8K:25, 10K:35,
12K:45, 14K:60, 16K:80) multiplié par le multiplicateur de credits du modèle
(Magnific ×3) ; Crystal au-dessus de 12K facture par mégapixels de sortie. Les
estimated_credits de la réponse 202 correspondent exactement au débit. Voir

POST /images/upscales body (SAM-819 / S8.7 — ADR §7, §8, §10).
Upscale ONE source image to a higher target_resolution with one of the
four public models. The source is exactly one of image_id (an image in
your organization's context), an https url, or base64+mime_type.
target_resolution is a CLOSED set — the per-model factor/area caps are
validated BEFORE charging (an over-cap request is a 422, never a charged
job). options are per-model, typed, and STRICTLY validated (out-of-range /
unknown values are 422 — a documented deviation from the app's clamping).
Cost is the existing upscale estimator: the resolution tier
(2K:5, 4K:10, 6K:20, 8K:25, 10K:35, 12K:45, 14K:60, 16K:80) x the model
credit multiplier (Magnific x3); Crystal above 12K prices by output
megapixels. estimated_credits in the 202 equals the deduction exactly.
The source image: exactly one of image_id, an https url, or base64+mime_type.
Target resolution class (REQUIRED) — one of 2K, 4K, 6K, 8K, 10K, 12K, 14K, 16K, 20K, 24K, 28K, 32K, 38K. Classes above 16K are only valid for crystal. The per-model factor/area caps are validated before charging.
2K, 4K, 6K, 8K, 10K, 12K, 14K, 16K, 20K, 24K, 28K, 32K, 38K "4K"
Upscale model: seedvr, crystal (default), magnific-creative, or magnific-precision.
seedvr, crystal, magnific-creative, magnific-precision "crystal"
Per-model tuning options (typed). Only magnific-creative and magnific-precision accept options — supplying options for seedvr/crystal is a 422.
Optional https webhook notified once on terminal status (signed per the webhook signature scheme; see the webhooks docs).

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.
The job id — poll the op's GET .../{id} endpoint.
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).
pending, processing, completed, failed, cancelled "pending"
Credits this job is expected to cost — 0 on a cache-hit completed response.
