Getting started
Getting started
Pick your SDK and be running in under 5 minutes.
All three SDKs expose the same core API — token, tokens, connections, billing, events, webhooks — with small language-specific differences (e.g. Python adds module-level shortcuts and a sync session() helper; JS adds a top-level data API). See each quickstart for the exact surface.
Pick your language
Python quickstart
For FastAPI, Flask, Django, or any Python backend
TypeScript quickstart
For Node.js, Express, Next.js, or any JS runtime
Swift quickstart
For iOS, macOS, tvOS, and watchOS apps
What you need
- OSS mode: no account required. Just set the conventional env var for each integration (e.g.
OPENAI_API_KEY). - Vendo mode: a
VENDO_API_KEYfrom the Vendo dashboard. Set it once and everything lights up.
