WAN 2.7 API Limits: Resolution, Inputs and Request Boundaries

APIMART serves WAN 2.7 through POST /v1/videos/generations. The current documentation describes an asynchronous submit-and-poll workflow. The boundaries below were checked on September 2, 2026.

Verified boundaries

• wan2.7 is a unified text-to-video and image/video-conditioned endpoint that returns an asynchronous task_id.
• Duration supports 2 through 15 seconds.
• Resolution supports 720P and 1080P.
• Prompt length is up to 5,000 characters.
• The backend routes to conditioned generation when image_urls, image_with_roles or video_urls is present.
• The endpoint supports custom audio; its role differs between text-only and image-conditioned workflows.

Minimal integration rule

Send the documented model ID, required prompt and only compatible optional inputs. Persist the returned task_id, implement bounded polling and backoff, and keep 400, 401, 402, 429 and 5xx responses out of completed-output metrics.

FAQ

Which endpoint serves WAN 2.7?

Use POST /v1/videos/generations with the documented model ID and Bearer authentication.

Is processing synchronous?

No. A successful submission returns a task ID that must be polled for completion.

What is the first production safeguard?

Validate model ID, quantity or duration, resolution and input combinations before submission.

Can documented limits change?

Yes. Treat the live endpoint documentation as the source of truth and version your request profile.

Should a submitted task be counted as completed output?

No. Count success only after the task endpoint reports a completed result.
