API Key

Run the init command above, or set AI_HIVE_API_KEY, use --api-key, or create ~/.ai-hive/config.json. API keys use the sk-api-* format. Never commit a real API key.

Reliability and Cost

The script looks up the live model entry and pricing snapshot at runtime. Model availability, reference-image limits, parameters, and prices can change. Keep a returned task ID and query the existing task instead of submitting a duplicate that may be billed twice.

Troubleshooting

• Missing reference image: add the number of --image inputs required by this skill.
• 401 Unauthorized: verify that the API key is complete, active, and not committed to source control.
• Invalid parameter: inspect the current imageConfig for accepted values and image limits.
• Local timeout: keep the task ID and use the task command later.
