Public API v2

The v2 public API generates presentations using SlideSpeak’s next-generation models for noticeably higher-quality output. You provide a prompt — optionally with your own documents and a design kit — and v2 produces a polished PowerPoint end to end.

Built for quality

v2 is focused on generation quality and design kits. It is actively growing — more capabilities will arrive over time.

All v2 examples use this base URL:

https://api.slidespeak.co/api/v2

All endpoints require the X-API-Key header.

Endpoints
