krea/krea-2-large with the Comfy Router API. Krea provides the model; Router gives it the shared authentication and request route below.
Quick start
Create a key at platform.comfy.org/profile/api-keys 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: krea/krea-2-large
Endpoint: POST https://api.comfy.org/v2/models/krea/krea-2-large

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: completedExamples

Before you ship
Save oneIdempotency-Key for each call and reuse it for retries. Router can hold the connection for up to 10 minutes. The SDKs handle authentication; raw HTTP clients send the headers themselves.
Use X-Comfy-Error-Type to classify a failure. 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
Find models, inspect schemas, and retry safely.
Limitations
What Router does not do today, and what to use instead.
