Krea.ai API

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

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

height=1024
)
print(urls)

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

{skill}/SKILL.md

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

Model not found

Run

python3 krea_api.py --list-models
