What does it cost a utility to add e.g. read-only OAuth token support to their customer-facing app?

FWIU, it's pretty easy to add OAuth support to any HTTP API endpoint with e.g. Nginx auth_request or by integrating an OAuth library with automated tests into the application at the url routes, if nothing else.

Do you have a "Guide for utilities who want users to have a safe third-party read-only API", a Developer portal, or like a decision tree for which script to read a decision-maker or a front-line lackey who doesn't know anything about APIs?
