For your agent
No official API. An agent should not scrape the site: use it by hand or through its downloads.
- A public notebook can be loaded as an ES module from api.observablehq.com/@user/notebook.js?v=4 and run with @observablehq/runtime; for new projects prefer the open-source Framework or Notebook Kit (ISC).
- Keep the ISC copyright notice when you copy Observable's library code
- Check each notebook's own license before reusing its code or data; notebooks belong to their authors
Paste into your agent: Read https://agentgid.com/resources/observable/agent.md before using Observable.
What you can build
- A static dashboard built with Observable Framework and data loaders, hosted anywhere
- Embedding a chart from a public notebook in your own page via the Observable Runtime
- Learning D3/Plot by forking gallery notebooks and porting them into your app

The Pudding
Each story asks a playful question about everyday culture and answers it with a dataset you can open and reuse yourself.

Information is Beautiful
Messy, argued-over topics are turned into single charts you can take in at a glance and then check against the source spreadsheet.
