Sure - PostgREST provides a RESTful API endpoint for any PostgreSQL database. It's kinda magic.

It's an interesting beast: it has almost no configuration at all, you just point it to one database schema, and it then uses the postgres permissions system to decide what tables & views to expose, and who gets to see them.

The only part of it that was a little tricky was creating multiple database users for anonymous views off the internet vs. internal staff who would want to do more than just select some rows.
