Use Krea 2 Medium Turbo with Comfy Router

API Reference for krea/krea-2-medium-turbo, served by Comfy Router from Krea.

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: krea/krea-2-medium-turbo Endpoint: POST https://api.comfy.org/v2/models/krea/krea-2-medium-turbo

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(
        "krea/krea-2-medium-turbo",
        {
            "aspect_ratio": "1:1",
            "prompt": "a red circle",
            "resolution": "1K",
        },
    )

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("krea/krea-2-medium-turbo", {
  aspect_ratio: "1:1",
  prompt: "a red circle",
  resolution: "1K",
});

console.log(data);

curl https://api.comfy.org/v2/models/krea/krea-2-medium-turbo \
  -H "X-API-Key: $COMFY_API_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \

Schema

Input

string

required

Aspect ratio. One of: 1:1, 4:3, 3:2, 16:9, 2.35:1, 4:5, 2:3, 9:16.Possible values: 1:1, 4:3, 3:2, 16:9, 2.35:1, 4:5, 2:3, 9:16

string

default:"\"medium\""

Prompt interpretation strength: raw=0, low=10, medium=50, high=100.Possible values: raw, low, medium, high

object[]

Style references to use for the generation

number

required

Range: -2 to 2Format: double

string (uri)

Format: uri

object[]

Moodboards to use for generation. Currently limited to one moodboard.

string (uuid)

required

Format: uuid

number

default:"0.35"

Range: -0.5 to 1.5Format: double

string

required

string

required

Resolution scale. One of: 1K.Possible values: 1K

number

object[]

Styles (typically LoRAs) to use for the generation

string

required

number

required

Range: -2 to 2Format: double

Generated from the schema Router serves at GET /v2/models/krea/krea-2-medium-turbo/openapi.json, the same document it validates a call against before the request reaches the provider.

Output

string (date-time)

required

Format: date-time

string (date-time)

required

Format: date-time

string (uuid)

required

Format: uuid

object

required

The finished generation. Not nullable here, unlike on KreaJob: a terminal job whose result carries no urls is answered as a Comfy Router error, so a 200 always carries it.

string

Set by loraTraining jobs rather than by a generation; a 200 for these models carries urls.

string (uri)[]

required

The generated images, as downloadable links. At least one, because a completed job with an empty urls is success_without_output and never reaches this document.

string

required

Always completed on this document: it is the only status classifyKrea answers succeeded on, and Krea’s vocabulary is matched without a case fold.Possible values: completed

Examples

Input

  "aspect_ratio": "1:1",

  "resolution": "1K"

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

What Router does not do today, and what to use instead.
