Request Body

application/jsonRequired
metadataMetadata

Caller-supplied metadata; ≤16 keys, key ≤64 chars, value ≤512 chars

callback_urlCallback Url

HTTPS URL Beatra will POST the final Task envelope to when the Task reaches a terminal state

callback_signing_key_idCallback Signing Key Id

Optional standalone callback signing key. Omit for unsigned callback delivery; requires callback_url when provided.

modelModel

Use auto for request-dependent selection from the ordered live candidates. A concrete model is evaluated exactly as requested and is never substituted.

Default: "auto"Value in: "auto" | "wan3.0-video" | "wan3.0-video-prime" | "happyhorse-1.0-video-edit" | "wan2.7-videoedit" | "seedance-2" | "seedance-2-fast" | "seedance-2-mini" | "seedance-2.5"
negative_promptNegative Prompt

Content or qualities to avoid when supported by the selected model.

durationDuration

Requested output duration as integer seconds, or 'auto' when the selected model may choose its documented duration. Omit to use the selected model default.

aspect_ratioAspect Ratio

Explicit output ratio when the selected model accepts it. Omit for a declared model default, source-derived ratio, or fixed model behavior.

resolutionResolution

Requested model-defined output resolution tier. Omit to use the selected model's declared default; unsupported tiers are rejected rather than coerced.

seedSeed
enhance_promptEnhance Prompt

Ask the selected model to rewrite the prompt before generation. Omit or use null to keep the prompt exactly as written.

watermarkWatermark

Whether generated video should include the model watermark.

generate_audioGenerate Audio

Whether the selected model should generate synchronized audio.

web_searchWeb Search

Whether the selected model may use web search during generation.

return_last_frameReturn Last Frame

Whether to return the generated video's last frame as an image artifact.

output_formatOutput Format

Optional output container. Omit or use mp4 for the existing default; models that advertise mov can return MOV without transcoding.

source_video
Required
Source Video

Required video whose existing content will be edited.

instruction
Required
Instruction

Required instruction describing changes to the source video.

Minimum length: 1Maximum length: 20000
referencesReferences

Optional ordered image, video, or audio references. The selected model must support every supplied reference kind and count.

audio_settingAudio Setting

Optional edit-audio policy: auto lets a compatible model choose, while origin requests preservation of source audio.

Header Parameters

X-Request-Idstring

Optional client request id echoed in the response.

Idempotency-Key
Required
Idempotency-Key
Minimum length: 1Maximum length: 128
Authorization
Required

Bearer API key.
