Getting started

Quick start

Five steps. You will have your first HappyHorse 1.0 result in the next minute.

  1. Sign up for a fal key. Create one at fal.ai/dashboard/keys. Copy it now; you will not see it again.
  2. Export it. export FAL_KEY=fal_... in your shell, or add it to a .env.local. Never commit it.
  3. Pick a snippet. The three below hit the same endpoint (fal-ai/happyhorse/v1/text-to-video) with a minimal input derived from the default parameter set.
  4. Run it. The first call takes a few seconds; subsequent ones are faster. You get a response URL pointing at a video.
  5. Iterate. Try the playground to see a chat-style interface, or jump to the API reference for every parameter.
