Fall is upon us 🍂 in Colorado with cooler weather and the start of fall colors in the high country. Let's see what API insights we have this week.
First, we look beyond the response code when monitoring REST APIs. This is a great article that asks, "What should we be monitoring when we receive a 200 OK response?". Nordic APIs has a look at the ways that traditional API design has changed forever, from designing for machines to moving toward capabilities. I covered this in my recent report as well, so check that out if you haven't yet. We also explore how developer portals need to evolve with AI agents, and Bump's API workflow specification called Flower Spec. Kin Lane looks at how OpenAPI is used (and spelled) across his catalog. Finally, we have an article for GraphQL fans - how Reverb moved from a monolith GraphQL stack to a federated GraphQL model with zero client disruption.
-- Happy Reading!
