Alibaba's Wan 2.7 Image Spicy family is now available through Siray's API: two standard endpoints at $0.03 per image and two Pro endpoints at $0.075 per image, each in a text-to-image and an image-to-image variant. This is the image branch of Wan 2.7, not the video branch. The video endpoints covered in Wan 2.7 Uncensored Video Generation Is Now Live on Siray use a different path, a different schema, and a different billing unit. Nothing in this article applies to them.

Key TakeawaysFour endpoints: alibaba/wan-2.7-image-t2i-spicy, alibaba/wan-2.7-image-i2i-spicy ($0.03 per image), alibaba/wan-2.7-image-pro-t2i-spicy, alibaba/wan-2.7-image-pro-i2i-spicy ($0.075 per image). All four are marked "New" in the Siray console as of October 8, 2026.All four take POST /v1/images/generations/async and require size (1k or 2k) plus one of 15 aspect_ratio values.n goes up to 12 outputs per call, the highest in Siray's image catalog.Standard and Pro have identical request schemas. The 2.5× price gap is for the model, not for extra parameters.There is no negative_prompt field on any of the four.

The Four Endpoints

Prices are per output image as shown in the Siray console on October 8, 2026, with no discount badge. The i2i variants add a required images array (1 to 9 URLs or data URLs); everything else is shared.

What All Four Share

Every call needs model, prompt, size, and aspect_ratio. size is 1k or 2k. aspect_ratio accepts 15 values: 1:1, 1:2, 2:1, 1:3, 3:1, 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 9:21, and 21:9. The 1:3, 3:1, 9:21, and 21:9 entries cover banner and ultra-wide formats most competitors skip.

Optional fields:

• n — 1 to 12 outputs per call, default 1. Each output is billed separately.
• seed — -1 to 2147483647.
• prompt_expansion_enable — defaults to true, which means the model rewrites your prompt before generation unless you set it false.
• enable_sequential — boolean, enables sequential group image output.
• color_palette — an array of {hex, ratio} objects to pin a color theme.
• bbox_list — nested arrays of [x1, y1, x2, y2] boxes marking edit regions, aligned to the input images.

Standard vs Pro: Same Schema, 2.5× the Price

A field-by-field diff of the four OpenAPI specs shows that Standard and Pro are identical except for the model enum. Pro does not unlock a larger size, a wider n range, or any extra parameter. Whatever Pro delivers for $0.075 instead of $0.03 is inside the model weights; this article makes no claim about output quality. Run the same prompt and seed on both before committing a budget to Pro.

For context inside Alibaba's own NSFW image lineup on Siray, Qwen Image 3 Pro Spicy sits at $0.035 (standard) and $0.046 (Pro) per image. Wan 2.7 Image Spicy undercuts it at the standard tier and overshoots it at Pro.

What's Not There: negative_prompt

None of the four Wan 2.7 Image Spicy endpoints accept negative_prompt. This is the opposite of the Wan 2.7 video family, where negative_prompt still matters. On the image side, anything you want excluded has to be written into the positive prompt, and prompt_expansion_enable: false becomes more important because the rewrite step can reintroduce what you left out.

A First Call

POST https://api.siray.ai/v1/images/generations/async
{
  "model": "alibaba/wan-2.7-image-t2i-spicy",
  "prompt": "studio portrait, adult woman, soft key light, neutral grey backdrop, 85mm lens",
  "size": "2k",
  "aspect_ratio": "4:5",
  "n": 4,
  "seed": 20261008,
  "prompt_expansion_enable": false
}

The response is an async task ID; poll it for four 2k images at 4:5, $0.12 total.

Cost at Scale

A full n: 12 batch on the standard t2i endpoint costs $0.36. The same batch on Pro costs $0.90. A hundred standard images come to $3.00; a hundred Pro images to $7.50. For reference, Z-Image Spicy Pro runs $0.020 per image, so the standard tier is not the cheapest NSFW image endpoint on Siray, but it has the widest aspect-ratio list and the highest n ceiling.

A Note on Compliance

Siray's NSFW and uncensored models generate legal, consensual adult content for verified adults only. CSAM and any other illegal content are refused with zero tolerance. Wan 2.7 Image Spicy is a third-party model from Alibaba available through Siray's API, not a Siray-hosted model, and the same standard applies to everything generated with it.
