Getting started

Create an API key and generate your first video over HTTP.

The Simi API generates narrated whiteboard explainer videos from a prompt, optionally grounded in a document. The base URL is https://api.laminalabs.ai.

1. Create an API key

Log in to the Simi app, open API Keys from your workspace, and create a key. Keys look like lamina_live_… — treat them like passwords and keep them out of client-side code.

2. Submit a job

curl

curl -X POST https://api.laminalabs.ai/v1/jobs \
  -H "Authorization: Bearer $LAMINA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "payload": {
      "prompt": "Explain how photosynthesis works, for a middle-school class.",
      "options": { "duration": 60 }
    }
  }'

duration is in seconds, up to 300. The response contains a job id you can poll; the SDKs can also stream progress events.

3. Poll the job and fetch the video

curl

curl https://api.laminalabs.ai/v1/jobs/$JOB_ID \
  -H "Authorization: Bearer $LAMINA_API_KEY"

curl -L https://api.laminalabs.ai/v1/jobs/$JOB_ID/video \
  -H "Authorization: Bearer $LAMINA_API_KEY" -o out.mp4
