Before you start#

You need a Runway developer account and a payment method. The API is not available on a free tier — credits cost $0.01 each, with a $10 minimum first purchase.

Once you have a key, everything else on this site is reference material. The two pages you will come back to most are Models (what to call) and Pricing (what it costs).

  • Models — pick the right model before you write the call
  • Inputs — size limits and codecs your assets must satisfy
  • Usage tiers — how many generations you can run at once
Start with an account

Organization, key and credits take about five minutes.
