Wan 3.0 video API — early access

Modes and model IDs

Every mode uses the same request shape: model + prompt + media arrays (images / videos / audios / files as public HTTPS URLs) + params. Full field tables: API docs.

Prices (USD, base list)

Base list prices from the live price list (/pricing · pricing.json); the effective price for your key is returned by GET /ent/v2/prices. Cost is reserved at submit and settled on completion — failed tasks are refunded in full.

Example request

POST https://api.18models.ai/ent/v2/generate
Authorization: Bearer sk-…
Content-Type: application/json
Idempotency-Key: <stable-request-id>

{
  "model": "wan3.0-video-reference-uncensored",
  "prompt": "Image 1 is the character, Audio 1 is her voice. She reads the line while turning to camera.",
  "images": ["https://cdn.example.com/character.jpg"],
  "audios": ["https://cdn.example.com/line.mp3"],
  "params": { "resolution": "720p", "duration": 8 }
}

The response is HTTP 202 with a task_id; poll GET https://api.18models.ai/ent/v2/tasks/{task_id} (back off 2 s → 5 s) until status is success or failed, then read result_urls. Ready-made client code: docs → Build with AI or the Agent Skill.

What is allowed

NSFW output is permitted under the 18models Content Policy: fictional adult content, including explicit sexual content, is allowed; content involving minors (in any style) or real, identifiable people is prohibited absolutely and screened on both input and output. Upstream providers apply their own checks in addition to ours — a task rejected upstream fails and is refunded automatically.

• Preview-period pricing; input video/audio duration is billed together with output duration on reference mode.
• Same content policy as every model: fictional adults only; real people's images, videos and voices are prohibited as NSFW references.

FAQ

What is different about Wan 3.0 compared with Wan 2.7?

Longer clips (2–30 seconds instead of 2–15), an adaptive aspect ratio option, prompts up to 20,000 characters, a multimodal reference mode that mixes images, video and audio, and document-to-video. Wan 2.7 remains the choice for video edit and storyboard modes.

How much does the Wan 3.0 API cost?

Preview-period pricing is $0.058 per second at 480p, $0.115 at 720p and $0.231 at 1080p. Input video/audio duration is billed alongside output duration on reference mode.

Is Wan 3.0 NSFW-capable on 18models?

Yes, under the same content policy as every other model: fictional adult content allowed, minors and real people prohibited and screened.
