Use FLUX Pro 1.0 Depth with Comfy Router

API Reference for bfl/flux-pro-1.0-depth, served by Comfy Router from Black Forest Labs.

Quick start

Create a key at platform.comfy.org/profile/api-keys and export it as COMFY_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/flux-pro-1.0-depth Endpoint: POST https://api.comfy.org/v2/models/bfl/flux-pro-1.0-depth

from comfy_sdk import Comfy

# Reads COMFY_API_KEY from the environment. Each call sends a fresh
# Idempotency-Key and waits up to 10 minutes for the finished result.
with Comfy() as client:
    result = client.models.run(
        "bfl/flux-pro-1.0-depth",
        {
            # Request fields are the provider's own — see Input below.
        },
    )

print(result)

import { comfy } from "@comfyorg/sdk";

// Reads COMFY_API_KEY from the environment. Each call sends a fresh
// Idempotency-Key and waits up to 10 minutes for the finished result.
const { data } = await comfy.models.run("bfl/flux-pro-1.0-depth", {
  // Request fields are the provider's own — see Input below.
});

console.log(data);

# Request fields are the provider's own — see Input below.
curl https://api.comfy.org/v2/models/bfl/flux-pro-1.0-depth \
  -H "X-API-Key: $COMFY_API_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{}'

Schema

Input

Router has not published an authored input schema for this model yet: GET /v2/models/bfl/flux-pro-1.0-depth/openapi.json returns an open object with x-comfy-input-schema-authored: false. Router forwards the body to Black Forest Labs unchanged, so Black Forest Labs’s own API reference is authoritative for the request fields, and nothing is validated server side.

Output

number

Provider-reported cost in credits, populated once the task is Ready.Format: float

string

required

BFL task identifier.

number

Optional generation progress reported by BFL.Range: 0 to 1Format: float

object

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: double

number

Provider-reported generation duration in seconds.Format: double

number

Provider-reported completion time of the generation, in seconds since the Unix epoch. double for the same reason as start_time.Format: double

string

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: uri

integer

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: int64

number

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: double

string

required

Task status: Pending, Reasoning, Generating, Ready, Request Moderated, Content Moderated, Error, or Task not found.

Before you ship

The snippets above are the shortest working call. Three things are the same for every model and are documented once on the Comfy Router headers page: send an Idempotency-Key on every paid call and reuse it when you retry, expect the connection to be held up to Router’s 10 minute deadline, and keep X-Comfy-Request-Id from every response. The SDKs do all three for you; the cURL tab does none of them. On failure, X-Comfy-Error-Type names the bucket, and a 422 means the body failed the model’s schema and was never billed.

Headers

Authentication, idempotency, request IDs, error buckets, retry pacing, spend limits.

Quick Start

Typed error handling in Python and TypeScript, reading the 422, walking the catalog.

Limitations
