Sign up and generate an API key from the dashboard.
Choose the version that best matches your quality and cost requirements.
Submit your prompt and parameters to the model's documented endpoint.
Poll the task or set a webhook, then download the completed output.
Use one RunAPI model ID for text-to-video and image-to-video. Reference mode accepts up to 9 images, 3 videos, and 3 audio clips; audio references must accompany an image or video reference.
A single RunAPI API key unlocks the whole model catalog across all providers. No separate accounts to create, no API keys to rotate per integration, and no credential management overhead. Add a new model to your app by changing one parameter.
Per-call pricing in USD, billed monthly into a single invoice. No subscription tiers, no minimum spend, and failed generations are never charged. The pricing page and check_pricing API show exact costs before you commit to a model.
Typed schemas, parameter constraints, and setup notes are packaged in the model skill so your implementation starts from the right contract. The skill loads into Claude Code, Codex, Gemini CLI, Cursor, and VS Code — your agent knows the correct request shape before you write a line of code.
Use a text prompt, a first or final frame, or multiple reference images, videos, and audio clips. Outputs support 4–15 seconds at 768p or 2K.
Pick the cheapest variant that meets your quality bar. Most teams start on the fast variant and graduate to pro for production.
Creating an account and API key is free. API calls use prepaid, pay-as-you-go billing; add funds before making requests.
Where streaming is available, RunAPI streams end-to-end.
Failed generations are not charged.
Generated outputs are stored and retrievable by task ID. Inputs are not cached.
