# auray-serverless/krea/krea-2-large

`POST https://queue.auray.run/auray-serverless/krea/krea-2-large` submits; the response carries a `request_id` and the three URLs to use next.

`POST https://auray.run/auray-serverless/krea/krea-2-large` is the same request run synchronously: the connection is held and the response is the model's OUTPUT, the same document the result URL would have answered. A request that usually takes longer than a run may hold its connection is refused `400 model_not_synchronous` there before anything is charged, naming `expected_seconds` and `wait_ceiling_seconds` — submit it to the queue instead. Past the deadline a run is `504 run_timed_out` with `X-Auray-Request-Timeout-Type: user` — the request is still alive, running and charged or, while it waits to start, not yet charged (`charged` says which) — so poll `status_url` rather than resending, or resend with the same `idempotency_key` to be handed this request again instead of a second one. A run holds one of the connections this platform, this product and your account may keep waiting; with all of them in use it is refused `429 wait_capacity` with `Retry-After` before anything is charged (`charged: false`), and retrying after that pause is safe.

One of Auray's catalogue models, billed once in credits. Whether it runs right now is `GET /v1/catalogue`'s `addresses` (no key needed): `connected` runs; `described` answers `501 model_not_connected` and `paused` `503 model_disabled`, both before anything is charged.

Price: Credits per megapixel (counted as `width*height`): 5.6123 for settings.creativity=low; settings.creativity=medium; 5.7782 for settings.creativity=raw; settings.creativity=high. Each band has its own least and most a request is counted at. Priced up to height 1376, width 1568; past that a request is refused before any charge. Quoted when you submit, at the most the request can cost; the charge settles to what the job cost and never above the quote.

## Input

- inputs.referenceImages (array of url, optional) — Style reference images for guiding generation. Each item can be a plain image input (an http(s) URL; upload a local file first and send its read URL) or an object with an image and a per-image strength. **Examples**: **Shorthand format:** When you don't need to specify a custom strength, you can pass a plain image input directly. It will use the default influence strength. ```json "referenceImages": [ "aac49721-1964-481a-ae78-8a4e29b91402" ] ``` **Object format:** When you need to control the exact influence of the reference image, use an object with `image` and `strength`. Positive values guide the output toward the reference; negative values guide away from it. ```json "referenceImages": [ { "image": "aac49721-1964-481a-ae78-8a4e29b91402", "strength": 0.7 } ] ``` **Multiple images:** You can provide multiple reference images and even mix both formats. ```json "referenceImages": [ "aac49721-1964-481a-ae78-8a4e29b91402", { "image": "3ad204c3-a9de-4963-8a1a-c3911e3afafe", "strength": 1.2 } ] ``` Documented range: 1 to 10.
- positivePrompt (string, required) — Text prompt describing elements to include in the generated output.
- width (integer, required, default: 928) — Width of the generated media in pixels.
- height (integer, required, default: 1152) — Height of the generated media in pixels.
- seed (integer, optional) — Random seed for reproducible generation. When not provided, a random seed is generated in the unsigned 32-bit range. Documented range: 0 to 9,223,372,036,854,776,000.
- settings.creativity (string, optional, default: "medium", one of: "raw", "low", "medium", "high") — Creativity level. Controls how closely the model follows the prompt versus generating its own interpretation.
- settings.moodboards[].id (string, optional, one of: "36faac0b-2b82-45b7-961f-5019cfc886c0", "0bff265b-ba63-468f-9acb-e38705a343b8", "99f3fd48-c434-4f50-a798-57d3a0e3c064", "1b1aaa13-b4dd-4db8-b550-0305324dd70b", "1c173dd2-e6b3-47f6-9565-93485cec15be", "29499086-a16b-4ee9-b04a-fdabea7e050b", "cb3a3e97-7eb6-4ed8-adee-18e384310f7c", "c3421c04-db95-4f18-a229-003227a54669", "4372ab77-fd8c-4c86-9c88-03b6f0d91ee3", "3b1ec8e1-3eda-467d-be5d-4fa5eda3b70c", "d4d96c37-a989-457a-94ee-6a0a968d178c") — Identifier of the moodboard to use as creative direction.
- settings.moodboards[].strength (number, optional, default: 0.23) — Influence strength of the moodboard on the generated output. Documented range: 0 to 1.
- outputType (string, optional, default: "URL", one of: "URL") — Image output type.
- outputFormat (string, optional, default: "JPG", one of: "JPG", "PNG", "WEBP") — Specifies the file format of the generated output. The available values depend on the task type and the specific model's capabilities. - \`JPG\`: Best for photorealistic images with smaller file sizes (no transparency). - \`PNG\`: Lossless compression, supports high quality and transparency (alpha channel). - \`WEBP\`: Modern format providing superior compression and transparency support. - \`MP4\`: Widely supported video container (H.264), recommended for general use. - \`WEBM\`: Optimized for web delivery. - \`MOV\`: QuickTime format, common in professional workflows (Apple ecosystem). - \`GIF\`: Animated image format (no audio), suitable for short loops or previews. - \`MP3\`: Compressed audio, smaller file size. - \`WAV\`: Uncompressed, high-quality audio. - \`FLAC\`: Lossless compression. - \`OGG\`: Open-source compressed audio format (Vorbis codec). - \`SVG\`: Scalable Vector Graphics. - \`TIFF\`: High-quality output supporting layers. - \`GLB\`: Binary glTF format for 3D models, including geometry, textures, and PBR materials. > [!NOTE] > \*\*Transparency\*\*: If you are using features like background removal or LayerDiffuse that require transparency, you must select a format that supports an alpha channel (e.g., \`PNG\`, \`WEBP\`, \`TIFF\`). \`JPG\` does not support transparency.
- outputQuality (integer, optional, default: 95) — Compression quality of the output. Higher values preserve quality but increase file size. Documented range: 20 to 99.
- safety.checkContent (boolean, optional) — Enable or disable content safety checking. Increases total generation time. Always on: a false is sent as true.
- advancedFeatures.watermark.text (string, optional) — Watermark text. Documented range: 2 to 32 characters.
- advancedFeatures.watermark.image (url, optional) — Watermark image (an http(s) URL; upload a local file first and send its read URL).
- advancedFeatures.watermark.displayPosition (string, optional, one of: "top-left", "top-center", "top-right", "center-left", "center-center", "center-right", "bottom-left", "bottom-center", "bottom-right", "tiled") — Watermark position.
- advancedFeatures.watermark.opacity (number, optional) — Watermark opacity. Documented range: 0.1 to 1.
- advancedFeatures.watermark.fontColor (string, optional) — Text color in hex format.
- advancedFeatures.watermark.bgColor (string, optional) — Background color in hex format.
- idempotency_key (string, optional) — Your own name for this request. Send the same one twice and the second call is answered with the first request rather than charged again. `Idempotency-Key:` as a header is accepted as an alias — that is the spelling a retrying proxy replays, and the one to use when running a model on `auray.run`, where a request that outlives its connection is answered 504 and recovered by replay. Omit it and the platform mints one.

## Rules

Across fields, as the model's documentation states them; judged before any charge, and warned (Deprecation) until enforcement starts.

- Send `height` whenever `width` is sent. Send `width` whenever `height` is sent.
- When `width` is sent or `height` is sent, `width` and `height` must be one of these: 1K (1:1): width 1024, height 1024; 1K (4:3): width 1184, height 896; 1K (3:2): width 1248, height 832; 1K (16:9): width 1376, height 768; 1K (2.35:1): width 1568, height 672; 1K (4:5): width 928, height 1152; 1K (2:3): width 832, height 1248; 1K (9:16): width 768, height 1376.
- `settings.moodboards` must hold exactly 1 item. In every item of `settings.moodboards`: `settings.moodboards[].id` is required.
- When `advancedFeatures.watermark` is sent: send exactly one of `advancedFeatures.watermark.text` or `advancedFeatures.watermark.image`.

## Response

A submit answers the status document (`status`: IN_QUEUE, IN_PROGRESS or COMPLETED; `request_id`;
`queue_position` while queued; `logs`; `metrics`) and then, beside it:
- product (string) — Which of this platform's products ran it.
- provider_job_id (string) — The id the job runs under, once it has been handed to its model — possibly while still `queued`; null before. Quote it to support.
- model (string) — The address that ran it, echoed back.
- engine (string) — The service's own name for the model that ran, where it reports one — a catalogue model's is its `id` on GET /v1/models; null otherwise. What `model` carried before it carried the address.
- attribution (string) — The credit line the model's licence requires you to show; null where none is required.
- credits_charged (integer) — What this job cost. 0 on a replay, or when a pass or a promotion paid for it (`coverage` says which).
- credits_quoted (integer) — What this job costs, in credits: the price it was quoted at submit. Equal to `credits_charged` once it has been charged; while it waits in the queue to start, `credits_charged` is 0 and this is what it will be charged when it starts (a cancel before then costs nothing) — and a replay of a job still waiting quotes the body that job was queued with, which is the one it runs, not the replay's. For a catalogue model it is the hold, and the settle may give part of it back — a settled read's `credits_charged` says what it finally cost.
- coverage (object) — Present when a pass or a promotion paid for this job — `{"by": "pass", "pass": "seedance-2-5"}` or `{"by": "promotion"}`, and `credits_charged` is 0 — or when you hold a pass for this model that did not cover this job: `{"by": null, "miss": {"pass": "video", "why": "door"}}`, `why` being `door` (the pass does not work here) or `shape` (it does not cover this kind of job). Absent otherwise. Send `X-Auray-Covered-Only: 1` to run a job only if a pass or a promotion pays for it.
- credits_remaining (integer) — The balance after it.
- expected_seconds (integer) — A rough render time, for a progress bar; 0 where nothing is published.
- give_up_after_seconds (integer) — The longest this job may take from its submit: the longest it may wait to start (your X-Auray-Request-Timeout, or the product's queue deadline) plus the longest it may run before it is stopped and refunded. Waiting longer is waiting for nothing; the official clients wait this long by default. For a catalogue model the part it may run is its own reap as its registry row states it (`lifecycle.stall_ceiling_seconds` on GET /v1/models); otherwise these are the published limits: we may lengthen them during an incident, never shorten them.
- replayed (boolean) — `true` when your `idempotency_key` matched a job this platform already had. Nothing was charged and nothing was rendered twice.
- waited (boolean) — Present when `wait` was asked for. The rest of this group comes with it.
- timed_out (boolean) — The wait ran out before the job settled. Still a 2xx, never a 408 or 504 — a library that retries on those would resubmit and you would pay twice. Poll `status_url`.
- wait_declined (string) — No seat was free to hold the connection with, so the request was answered at once. `platform_busy`: no product would have helped. `product_busy`: another product's queue might. `account_busy`: you are already waiting on every seat your plan's lanes allow. The job is running either way; poll it.
- status_url (string) — Poll this.
- response_url (string) — Fetch the result from this once the status is COMPLETED.
- cancel_url (string) — `PUT` to this to ask for a cancellation.
Poll `status_url`, fetch `response_url` once COMPLETED, `PUT` `cancel_url` to stop it.
