The Overten API gives you programmatic access to the same AI agents that power the Overten web app. Send a prompt, receive a polished .xlsx, .docx, or .pptx — no templates, no code generation, no manual formatting. Every document is fully editable and can be iterated on with follow-up prompts.

How it works

1

Get an API key

Sign up at app.overten.ai or call POST /signup programmatically. You’ll receive a sk_live_* key that authenticates every request.
2

Generate a document

Call POST /excel/generate, /word/generate, or /slides/generate with a natural-language prompt. The API returns a download_url pointing to your finished file.
3

Download or embed

Fetch the file directly, or use the edit_url to embed Overten’s in-browser editor in your own app so end users can refine the document themselves.
4

Iterate

Pass the run_id back on your next call to resume — the agent remembers what it built, so follow-up turns are faster and cheaper.

​
What you can build

  • Report generators — feed data and a prompt, receive a polished spreadsheet with charts and formulas
  • Deck builders — turn a sales brief into a presentation with cohesive branding
  • Proposal automation — merge dynamic client data into well-formatted Word documents
  • Document analysis — ask natural-language questions of an existing Excel or Word file without producing a new one
Every generation endpoint supports async: true. Submit long-running jobs asynchronously and receive results via webhook when ready.
