Krea.ai Image Generation Skill

Generate images using Krea.ai's API with support for multiple models including Flux, Imagen 4, Ideogram 3.0, and more.

Features

• ✅ Async job-based generation (POST → poll → result)
• ✅ Support for multiple image models
• ✅ Configurable parameters (width, height, steps, guidance, seed)
• ✅ Stdlib-only dependencies (no requests required)
• ✅ Secure credential handling with file permissions

Security

This skill prioritizes security:

• No webhook support - Removed to prevent SSRF risks
• Stdlib dependencies - Minimal attack surface (uses urllib only)
• File-based credentials - Primary credential source with secure permissions
• Input validation - All parameters validated before API calls

Credential Sources (in order of precedence)

1. CLI arguments: --key-id and --secret (for one-off use)
2. File: ~/.openclaw/credentials/krea.json

Note on Subprocess

The --usage flag uses webbrowser.open() (stdlib) to open the usage dashboard in a browser. No subprocess calls.

Setup

1. Get your Krea.ai API credentials from https://docs.krea.ai/developers/api-keys-and-billing
2. Create the credentials file:

mkdir -p ~/.openclaw/credentials

1. Add your credentials:

echo '{"apiKey": "YOUR_KEY_ID:YOUR_SECRET"}' > ~/.openclaw/credentials/krea.json

1. Set secure permissions:

chmod 600 ~/.openclaw/credentials/krea.json

Usage

Command Line

# Generate an image
python3 krea_api.py --prompt "A sunset over the ocean"

# With specific model
python3 krea_api.py --prompt "Cyberpunk city" --model imagen-4

# Custom size
python3 krea_api.py --prompt "Portrait" --width 1024 --height 1280

# List available models
python3 krea_api.py --list-models

# Check recent jobs
python3 krea_api.py --jobs 10

Python Script

from krea_api import KreaAPI

api = KreaAPI()  # Reads from ~/.openclaw/credentials/krea.json

# Generate and wait
urls = api.generate_and_wait(
    prompt="A serene Japanese garden",
    model="flux",
    width=1024,
    height=1024
)
print(urls)

Parameters

Available Models

Run python3 krea_api.py --list-models for full list.

Check Usage

Krea.ai doesn't provide a public usage API. Check your usage at:

https://www.krea.ai/settings/usage-statistics

Or list recent jobs:

python3 krea_api.py --jobs 10

File Locations

Troubleshooting

"API credentials required"

1. Check credentials file exists:

ls -la ~/.openclaw/credentials/krea.json
# Should show: -rw-------

1. Verify format (must have colon):

{"apiKey": "KEY_ID:SECRET"}

⚠️ Security: Do NOT use cat to view the credentials file — it contains secrets.

Model not found

Run python3 krea_api.py --list-models to see available models.

Thanks to Claude Opus 4.5 for researching the correct API structure. The docs incorrectly suggest /v1/images/flux but the working endpoint is /generate/image/bfl/flux-1-dev.
