About

Everything on Endpoint Notebook is about APIs explained for non-programmers: what an API is, how a request and reply work, keys, limits and errors, and why AI tools and business apps use them.

Facts on these pages come from published sources, such as makers' documentation, official pages and reference works, and each page links to the ones it used. Every page shows when it was last checked.

There are no ads here, and nothing is for sale.

What you read here is general information. Your own equipment's manual comes first, and where safety or the law calls for a qualified tradesperson, use one.
