Getting started

All three SDKs expose the same API surface. The only difference is language idioms and install method.

Pick your language

For FastAPI, Flask, Django, or any Python backend

For Node.js, Express, Next.js, or any JS runtime

For iOS, macOS, tvOS, and watchOS apps

OSS mode: no account required. Just set the conventional env var for each integration (e.g. OPENAI_API_KEY).
Vendo mode: a VENDO_API_KEY from the Vendo dashboard. Set it once and everything lights up.

After your first token call, read Concepts: Two modes to understand the resolution chain, and Concepts: Multi-tenant if you are building a SaaS product.
