bfl/video-edit-v1, served by Comfy Router from Black Forest Labs.
Quick start
Create a key in your Comfy workspace and export it asCOMFY_API_KEY. The Python and TypeScript snippets use the Comfy SDKs (pip install comfy-sdk, npm install @comfyorg/sdk); the cURL snippet is the same call over raw HTTP.
Model ID: bfl/video-edit-v1
Endpoint: POST https://api.comfy.org/v2/models/bfl/video-edit-v1
Schema
Input
string
required
Edit instruction. Names the objects, setting, style, on-screen text or dialogue to change; everything not named is preserved.
integer
default:"2"
Tolerance level for input and output moderation, 0 being most strict.Range:
0 to 4string
required
Video to edit, either an HTTP(S) URL or a base64-encoded MP4. At most 15 seconds of source footage and 50 MiB, with each side at least 160 pixels; sources above 720p are downscaled to 720p.
GET /v2/models/bfl/video-edit-v1/openapi.json, the same document it validates a call against before the request reaches the provider.
Output
number
Provider-reported cost in credits, populated once the task is Ready.Format:
floatstring
required
BFL task identifier.
number
Optional generation progress reported by BFL.Range:
0 to 1Format: floatobject
required
The finished generation. Not nullable here: this component’s
required entry is a promise that a 200 carries the result, and a nullable result would reduce it to a key-presence check.number
Provider-reported cost of the generation. This is BFL’s number, not the Comfy charge.Format:
doublenumber
Provider-reported generation duration in seconds.Format:
doublenumber
Provider-reported completion time of the generation, in seconds since the Unix epoch.
double for the same reason as start_time.Format: doublestring
The prompt the generation actually ran, after any prompt upsampling.
string (uri)
Signed URL for the generated asset. Router re-hosts the asset onto Comfy storage and rewrites this field, so it is normally a Comfy-hosted URL valid for up to 24 hours - signed for 24 hours when minted, and replayed from a 23-hour memo, so a later poll can hand back one with as little as an hour left; a leaf whose re-host could not be performed keeps BFL’s own short-lived delivery URL instead - roughly two hours for video, roughly ten minutes for images. Either way the link expires, so download the asset rather than storing the URL.Format:
uriinteger
The seed the generation used, whether supplied or chosen by the provider. Declared
int64 because BFL returns seeds above 2^31 (e.g. 2784347701), which an unformatted integer generates as a 32-bit field in many SDK generators.Format: int64number
Provider-reported start time of the generation, in seconds since the Unix epoch.
double, not float: float32 spacing near a present-day epoch value is ~128 seconds, which collapses a whole generation’s span to a single decoded value.Format: doublestring
required
Task status: Pending, Reasoning, Generating, Ready, Request Moderated, Content Moderated, Error, or Task not found.

Before you ship
The SDKs create anIdempotency-Key and reuse it for automatic retries. For manual retries, reuse the original key. Router can hold the connection for up to 10 minutes.
When a request fails, Router sends an X-Comfy-Error-Type response header explaining why. A 422 means Router rejected the input before calling the provider. Download generated assets promptly because result URLs can expire.
Headers
Authentication, idempotency, request IDs, error buckets, retry pacing, spend limits.
Using the Router API
Model discovery, validation errors, retries, and billing.
