]

Conceptual Usage Example (Python)

Here’s how you can call the Generate Horror Poster action using a conceptual Python snippet:

import requests
import json

# Replace with your Cognitive Actions API key and endpoint
COGNITIVE_ACTIONS_API_KEY = "YOUR_COGNITIVE_ACTIONS_API_KEY"
COGNITIVE_ACTIONS_EXECUTE_URL = "https://api.cognitiveactions.com/actions/execute" # Hypothetical endpoint

action_id = "fb512ab4-4d8c-4248-8c42-bdecc5eebd66"  # Action ID for Generate Horror Poster

# Construct the input payload based on the action's requirements
payload = {
    "model": "dev",
    "width": 640,
    "height": 480,
    "prompt": "poster in style of TOK for a horror show, black and white, text on poster says \"MN Crew 2025 legally blond\", legally blonde. No gibberish, no other text",
    "imageFormat": "webp",
    "renderQuality": 90,
    "denoisingSteps": 28,
    "numberOfOutputs": 1,
    "outputAspectRatio": "1:1",
    "additionalLoraScale": 1,
    "loraApplicationScale": 1,
    "promptEffectStrength": 0.8,
    "diffusionGuidanceScale": 3.5
}

headers = {
    "Authorization": f"Bearer {COGNITIVE_ACTIONS_API_KEY}",
    "Content-Type": "application/json"
}

try:
    response = requests.post(
        COGNITIVE_ACTIONS_EXECUTE_URL,
        headers=headers,
        json={"action_id": action_id, "inputs": payload}  # Hypothetical structure
    )
    response.raise_for_status()  # Raise an exception for bad status codes (4xx or 5xx)

    result = response.json()
    print("Action executed successfully:")
    print(json.dumps(result, indent=2))

except requests.exceptions.RequestException as e:
    print(f"Error executing action {action_id}: {e}")
    if e.response is not None:
        print(f"Response status: {e.response.status_code}")
        try:
            print(f"Response body: {e.response.json()}")
        except json.JSONDecodeError:
            print(f"Response body: {e.response.text}")

In this code snippet, you’ll need to replace the API key and endpoint with your actual values. The input payload is structured according to the action's requirements, ensuring your request is correctly formatted.
