# Use AI Skin Enhancer Flexible with Comfy Router

> Call freepik/ai-skin-enhancer-flexible through Comfy Router: endpoint, request shape and the response Router returns.

Use `freepik/ai-skin-enhancer-flexible` with the Comfy Router API. Freepik 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](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:** `freepik/ai-skin-enhancer-flexible`

**Endpoint:** `POST https://api.comfy.org/v2/models/freepik/ai-skin-enhancer-flexible`

<CodeGroup>
  ```python Python theme={null}
  import uuid
  from comfy_sdk import Comfy

  # Reads COMFY_API_KEY from the environment. Store this UUID before starting a
  # generation. Use the same value if you retry it.
  idempotency_key = str(uuid.uuid4())
  with Comfy() as client:
      result = client.models.run(
          "freepik/ai-skin-enhancer-flexible",
          {
              "image": "https://img.magnific.com/free-photo/portrait-woman_395237-33.jpg?w=740&q=80",
          },
          idempotency_key=idempotency_key,
          timeout=660.0,
      )

  print(result)
  ```

  ```typescript TypeScript theme={null}
  import { comfy } from "@comfyorg/sdk";

  // Reads COMFY_API_KEY from the environment. Store this UUID before starting a
  // generation. Use the same value if you retry it.
  const idempotencyKey = crypto.randomUUID();
  const { data } = await comfy.models.run("freepik/ai-skin-enhancer-flexible", {
    image: "https://img.magnific.com/free-photo/portrait-woman_395237-33.jpg?w=740&q=80",
  }, { idempotencyKey, timeoutMs: 660_000 });

  console.log(data);
  ```

  ```bash cURL theme={null}
  # Run this line once. Reuse ROUTER_REQUEST_KEY if you retry the curl command.
  ROUTER_REQUEST_KEY=$(uuidgen)
  curl --max-time 660 https://api.comfy.org/v2/models/freepik/ai-skin-enhancer-flexible \
    -H "X-API-Key: $COMFY_API_KEY" \
    -H "Idempotency-Key: $ROUTER_REQUEST_KEY" \
    -H "Content-Type: application/json" \
    -d "{\"image\": \"https://img.magnific.com/free-photo/portrait-woman_395237-33.jpg?w=740&q=80\"}"
  ```

## Schema

### Input

<ParamField body="image" type="string" required>
  Input image. Supports Base64 encoding or HTTPS URL (must be publicly accessible).
</ParamField>

<ParamField body="optimized_for" type="string" default="&#x22;enhance_skin&#x22;">
  Optimization target for flexible skin enhancer

  Possible values: `enhance_skin`, `improve_lighting`, `enhance_everything`, `transform_to_real`, `no_make_up`
</ParamField>

<ParamField body="sharpen" type="integer" default="0">
  Sharpening intensity

  Range: `0` to `100`
</ParamField>

<ParamField body="smart_grain" type="integer" default="2">
  Smart grain intensity

  Range: `0` to `100`
</ParamField>

<ParamField body="webhook_url" type="string (uri)">
  Optional callback URL for async notifications.

  Format: `uri`
</ParamField>

Generated from the schema Router serves at `GET /v2/models/freepik/ai-skin-enhancer-flexible/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.

## Examples

### Input

```json theme={null}
{
  "image": "https://img.magnific.com/free-photo/portrait-woman_395237-33.jpg?w=740&q=80"
}
```

## Before you ship

Save one `Idempotency-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.

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](/development/comfy-router/reference#result-assets).
