RunAPI SDK selection

Use this skill to help an application developer pick and wire up RunAPI SDK packages for JavaScript, Ruby, or Go.

When NOT to use this skill

Do not use for one-off generation or agent-executed media tasks. If the user just wants an agent to create, edit, transform, or transcribe media once, use the RunAPI CLI (the runapi-cli skill) or the relevant model skill instead — not an SDK.

Reach for an SDK only when building a web app, backend, worker, library, or production codebase that calls RunAPI from its own code.

Core SDK vs model SDKs

• Core SDK — shared client primitives (auth, HTTP, polling, errors). Install it transitively via a model SDK; depend on it directly only for custom clients.
  • JavaScript / TypeScript: @runapi.ai/core
  • Ruby: runapi-core
  • Go: github.com/runapi-ai/core-sdk/go
• Model SDKs — one typed package per model line, built on the core SDK.
  • JavaScript / TypeScript: @runapi.ai/\x3Cmodel> (e.g. @runapi.ai/suno)
  • Ruby: runapi-\x3Cmodel> (e.g. runapi-suno)
  • Go: github.com/runapi-ai/\x3Cmodel>-sdk/go

Install only the model SDKs an application actually uses; each pulls the core SDK as a dependency.

Authentication

Keep the RunAPI API key in RUNAPI_API_KEY (or pass it to the client constructor); never commit secrets.
