TIL: SQL functions in Google Sheets to fetch data from Datasette

I put together some notes on patterns for fetching data from a Datasette instance directly into Google Sheets - using the importdata() function, a "named function" that wraps it or a Google Apps Script if you need to send an API token in an HTTP header (not supported by importdata().)

Here's an example sheet demonstrating all three methods.

WorkOS FGA: The Authorization Layer for AI Agents

workos.com/blog/agents-need-authorization-not-just-authentication?utm_source=daringfireball&utm_medium=newsletter&utm_campaign=q22026

My thanks to WorkOS for sponsoring last week at DF. Every AI agent demo looks magical, but most hit a wall in enterprise deployment. It’s not model quality or latency. It’s authorization. Authentication proves an agent’s identity. Authorization defines its blast radius.

The winners in enterprise AI won’t have the most features. They’ll be the ones enterprises can safely trust. Learn how WorkOS FGA scopes that blast radius with resource-level permissions, and read their deep dive for more.
