# Use Image Edit Increase Resolution with Comfy Router

> Call bria/image-edit-increase-resolution through Comfy Router: endpoint, request shape and the response Router returns.

API Reference for `bria/image-edit-increase-resolution`, served by Comfy Router from Bria.

## Quick start

Create a key at [platform.comfy.org/profile/api-keys](https://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:** `bria/image-edit-increase-resolution`

**Endpoint:** `POST https://api.comfy.org/v2/models/bria/image-edit-increase-resolution`

<CodeGroup>
  ```python Python theme={null}
  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(
          "bria/image-edit-increase-resolution",
          {
              # Request fields are the provider's own — see Input below.
          },
      )

  print(result)
  ```

  ```typescript TypeScript theme={null}
  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("bria/image-edit-increase-resolution", {
    // Request fields are the provider's own — see Input below.
  });

  console.log(data);
  ```

  ```bash cURL theme={null}
  # Request fields are the provider's own — see Input below.
  curl https://api.comfy.org/v2/models/bria/image-edit-increase-resolution \
    -H "X-API-Key: $COMFY_API_KEY" \
    -H "Idempotency-Key: $(uuidgen)" \
    -H "Content-Type: application/json" \
    -d '{}'
  ```
</CodeGroup>

## Schema

### Input

<ParamField body="desired_increase" type="integer">
  Resolution multiplier to apply. Supported values are 2 and 4. Maximum output resolution is 8192x8192.
</ParamField>

<ParamField body="image" type="string" required>
  The image to upscale. Supported input types are Base64-encoded string or URL pointing to a publicly accessible image file. Accepted formats JPEG, JPG, PNG, WEBP.
</ParamField>

<ParamField body="preserve_alpha" type="boolean">
  Controls whether partially transparent areas from the input image are retained in the output.
</ParamField>

<ParamField body="sync" type="boolean">
  When false (default), the request is processed asynchronously. When true, the API holds the connection open until complete.
</ParamField>

<ParamField body="visual_input_content_moderation" type="boolean">
  When enabled, applies content moderation to input visual. Returns 422 if the image fails moderation.
</ParamField>

<ParamField body="visual_output_content_moderation" type="boolean">
  When enabled, applies content moderation to result visual. Returns 422 if the output fails moderation.
</ParamField>

Generated from the schema Router serves at `GET /v2/models/bria/image-edit-increase-resolution/openapi.json`, the same document it validates a call against before the request reaches the provider.

### Output

Router does not publish an output schema for this model.

## 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](/development/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.
