Upscale an image to a higher resolution (all 4 models)
Agrandis une 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

Body
La réponse 202 est le handle de job asynchrone :
202 Accepted
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.
Les 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 un 422.
  • magnific_creative : prompt (≤ 500 caractères), optimized_for (standard · soft_portraits · hard_portraits · art_n_illustration · videogame_assets · nature_n_landscapes · films_n_photography · 3d_renders · science_fiction_n_horror), creativity/hdr/resemblance/ fractality (entiers −10…10), engine (automatic · magnific_illusio · magnific_sharpy · magnific_sparkle).
  • magnific_precision : sharpen/smart_grain/ultra_detail (entiers 0…100), flavor (sublime (défaut) · photo · photo_denoiser).

Credits

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 Tarifs.

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.

image
PublicImageEditSource · object
requis

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

target_resolution
enum<string>
requis

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.

Exemple:

"4K"

model
enum<string>
défaut:crystal

Upscale model: seedvr, crystal (default), magnific-creative, or magnific-precision.

Options disponibles:
seedvr,
crystal,
magnific-creative,
magnific-precision
Exemple:

"crystal"

options
PublicUpscaleOptions · object | null

Per-model tuning options (typed). Only magnific-creative and magnific-precision accept options — supplying options for seedvr/crystal is a 422.

webhook_url
string | null

Optional https webhook notified once on terminal status (signed per the webhook signature scheme; see the webhooks docs).

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).

Options disponibles:
pending,
processing,
completed,
failed,
cancelled
Exemple:

"pending"

estimated_credits
integer
requis

Credits this job is expected to cost — 0 on a cache-hit completed response.
