SANA — Base

Sana can synthesize high-resolution, high-quality images with strong text-image alignment at a remarkably fast speed, with the ability to generate 4K images in less than a second.

Initial reservationCalculate for your selected settings
Final chargeAdjusted to actual usage at your applicable plan rate
Calculate credits in the input panel for your selected settings.

Prices, estimates and credit deductions exclude tax. Any applicable tax is charged only when you buy plans or credits.

Initial credits remain deducted while final billing is pending. Final credits are adjusted after actual usage is confirmed.

  • Prices shown are estimates, not final charges. Final billing details will be available in Reports after generation is complete.

API

WEBOT API · Base

Generate from your server with your WEBOT account credits.

Use your 120-character WEBOT customer key (a–z, A–Z, 0–9). Send Authorization: Bearer YOUR_KEY. Keys are secrets: call from a server, never from public frontend code. Results come from verified webhooks and remain saved if your stream disconnects.
1. Configure your server
WEBOT_BASE_URL=https://webot.online
WEBOT_API_KEY=<your-server-side-WEBOT-key>

This base URL is resolved from verified domain mappings and your direct creator reseller. Forwarded Host headers are not trusted. New custom reseller domains need DNS, TLS and platform verification before activation.

2. Quote, then generate
MethodEndpointPurpose
POSThttps://webot.online/api/v1/models/creative_2af07c442f343525b47caa74/quoteValidate input and calculate credits (no deduction).
POSThttps://webot.online/api/v1/models/creative_2af07c442f343525b47caa74/requestsReserve quoted credits and queue an asynchronous job.
GEThttps://webot.online/api/v1/models/creative_2af07c442f343525b47caa74/requests/{request_id}/resultRead your saved result: 202 pending, 200 terminal.
GEThttps://webot.online/api/v1/models/creative_2af07c442f343525b47caa74/requests/{request_id}/eventsAuthenticated SSE: generation / terminal events.

Send JSON {"input":{…}} to quote. Send the same input plus integer quoted_credits to generate, with Authorization: Bearer … and Idempotency-Key. Use a unique 16–128 character key per new job; persist it and reuse the same key and input on any uncertain response. Never retry with a new key: that creates a second chargeable job.

Credits are reserved only after validation and a durable request is saved. A changed quote or insufficient balance returns 409. Credits exclude purchase taxes. The quoted amount is an initial reservation. After generation, the final charge replaces it using confirmed usage. Any verified unused allocation becomes available automatically; additional usage may require more credits. Missing billing stays pending, including for failed jobs.

3. Input example

Save this as input.json. Replace sample prompts, files and media URLs with your own. Schemas do not guarantee provider acceptance of the content.

5. Receive all results

The response includes a stable WEBOT request_id, events_url and result_url. Subscribe with a Bearer-authenticated HTTP stream. Nonterminal streams end after 25 seconds; reconnect to the same URL after at least 1.5 seconds. Current saved state is replayed immediately, including completion that happened while disconnected. A terminal event contains the result envelope. The JSON terminal flag describes generation completion. Keep reconnecting while financial_pending is true; stop after the terminal event confirms financial settlement. Never poll provider status/results. Native browser EventSource cannot send a Bearer header; keep the key on your server.

Completed output contains the full model result, including every generated media/document item, not just the first URL. Failed output is null with error and refund_state. Results are strictly limited to the key owner, including on reseller domains. Model-independent aliases: /api/v1/requests/{request_id}/result and /events. Revoking a key blocks subsequent reads and streams; saved results remain accessible with another valid key of the same account.

6. Schemas and parameter defaults

Required fields are marked with *. Required text must contain non-whitespace content. Defaults apply when an optional parameter is omitted; null, false, 0 and an empty array are distinct values. “No documented default” means WEBOT does not invent one. Examples are sample inputs, not defaults. WEBOT generation constraints can require an explicit value even when the provider publishes an automatic default.

Input schema · fields, constraints and defaults
ParameterTypeRequiredDefault when omittedDescription / constraints
num_imagesintegerNo1The number of images to generate.
minimum: 1 · maximum: 4
image_sizeobject | stringNo"square_hd"Choose an explicit output size. Custom dimensions: 512–4096 pixels, in multiples of 64.
image_size.variant0.widthintegerNo512The width of the generated image.
minimum: 512 · maximum: 4096
image_size.variant0.heightintegerNo512The height of the generated image.
minimum: 512 · maximum: 4096
enable_safety_checkerbooleanNotrueIf set to true, the safety checker will be enabled. Disabling it requires account authorization; unauthorized requests are always checked, and images flagged as unsafe are returned as black images.
sync_modebooleanNofalseIf `True`, the media will be returned as a data URI and the output data won't be available in the request history.
output_formatstringNo"jpeg"The format of the generated image.
enum: ["jpeg","png"]
promptstringYes *No documented defaultThe prompt to generate an image from.
negative_promptstringNo"" The negative prompt to use. Use it to address details that you don't want in the image. This could be colors, objects, scenery and even the small details (e.g. moustache, blurry, low resolution).
num_inference_stepsintegerNo18The number of inference steps to perform.
minimum: 1 · maximum: 50
seedinteger | nullNoNo documented default The same seed and the same prompt given to the same version of the model will output the same image every time.

How to use SANA — Base

Describe a picture in words. This model generates an image from your description; you do not need to draw it yourself.

Required inputs

  • Prompt: Your instructions to the model. Say what you want, include the important details and avoid contradictory directions. For a video, describe the action as well as the scene.

Workflow

  1. Prepare your source material and fill the required inputs above. Review the supported settings for this model.
  2. Sign in to calculate the credit estimate. Review the estimate before choosing Generate.
  3. Keep this model page open while the request runs. Completed results arrive in the result area; use the available player or download controls to review the output.

When to use this workflow

  • Create an illustration, concept or product scene.
  • Explore different visual styles for an idea.

Key settings

Prompt
Your instructions to the model. Say what you want, include the important details and avoid contradictory directions. For a video, describe the action as well as the scene.
Negative Prompt
Describe things you would prefer the model to avoid, such as unwanted blur or objects. This guides the result but is not a guarantee that those things will never appear.
Image Size
The output dimensions, usually width and height in pixels or a named size. Pixels are tiny dots that form a picture. More pixels make a larger image; they do not automatically make it more accurate. Choose a size suited to where you will use it. Supported choices: "square_hd", "square", "portrait_4_3", "portrait_16_9", "landscape_4_3", "landscape_16_9"
Width
The horizontal size: how wide the output is, usually in pixels. Changing it can also change the shape or crop. Respect the allowed increments as well as the minimum and maximum. Minimum: 512. Maximum: 4096. Increments of: 64
Height
The vertical size: how tall the output is, usually in pixels. Width and height together determine the shape and total pixel count. Minimum: 512. Maximum: 4096. Increments of: 64
Num Inference Steps
How many processing steps the model uses to build or refine the result. More steps can take longer; improvement usually has limits and too many steps do not guarantee better quality. Start with this model’s default. For training, steps mean learning updates instead. Minimum: 1. Maximum: 50
