Quick start — Leonardo AI API code examples

Submit a Leonardo AI image task with your Muapi key, receive a request ID, and poll the shared predictions endpoint for the generated image URL.

1. Submit a Leonardo AI job

curl -X POST https://api.muapi.ai/api/v1/leonardoai-phoenix-1.0 \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt":"A cinematic mountain observatory above the clouds at sunrise","aspect_ratio":"16:9"}'

# Response: {"request_id":"REQUEST_ID"}

The example calls Phoenix 1.0 with a prompt and 16:9 aspect ratio. Switch the endpoint slug to Lucid Origin or Motion 2.0 for another workflow.

2. Poll the result

curl https://api.muapi.ai/api/v1/predictions/REQUEST_ID/result \
  -H "x-api-key: YOUR_API_KEY"

Poll until the task completes, then read the generated image or video URL from the result response.
