The course looks intense, containing 17 chapters talking about Introduction to REST APIs, using APIs like a developer, Documenting API endpoints, the Open API spec, Testing API docs, Publishing API docs, and more. From the Course Introduction: "You'll first learn about API documentation by using a simple weather API to put a weather forecast on your site. [...] As you use the API, you'll learn about endpoints, parameters, data types, authentication, curl, JSON, the command line, Chrome's Developer Console, JavaScript, and more. The idea is that rather than learning about these concepts independent of any context, you learn them by immersing yourself in a real scenario while using an API. Immersion in real scenarios makes these tools and technologies more meaningful. "We'll then transition into standards, tools, and specifications for REST APIs. You'll learn about the required sections in API documentation, analyze examples of REST API documentation from various companies, learn how to join an open-source project to get experience, and more. "[...] We'll also dive into specifications such as the OpenAPI specification and Swagger UI (which provides tooling for the OpenAPI specification). Additionally, you'll learn how to document native library APIs and generate Javadoc". Tom Johnson offers a PDF version of this free course... over 900 pages, with more always being added. It also offers many workshop-like activities you could put in an actual itinerary. You would need for the course: Chrome, since it provides "a Javascript Console that works well for inspecting JSON", the JSON Formatter Chrome extension, Postman, a GitHub acco ## You can now read and search changelogs from the CLI DevFeed: [You can now read and search changelogs from the CLI]() Original publisher: [Read original article]() Author: Melkey Moksyakov Published: 2026-09-09T00:00:00Z Content type: release Language: en Sources: [Vercel News]() Topics: [Command-line interface](), [changelog](), [Vercel](), [Terminal](), [AI-assisted coding](), [JSON](), [Markdown]() Tags: [agents](), [changelog](), [cli](), [coding-agents](), [content](), [features](), [json](), [markdown](), [products](), [search](), [terminal](), [update](), [vercel]() ### AI overview Vercel introduces the vercel changelog command for reading and searching Vercel changelog entries from a terminal.

The article explains how this production identity mechanism relates to existing service account JWTs and addresses the security limitations of bearer tokens. ### Source excerpt Pod Certificate / Cluster Trust Bundles Blog Post Kubernetes brings a wealth of features that make it easy to run your production workloads securely and reliably. While aspects like scheduling, health checks and resource limits are probably at the front of your mind, one other important feature of Kubernetes is production identity -- how your workload can authenticate to other systems in order to do its job. Up until now, the primary production identity mechanism built into Kubernetes has been service account JWTs (JSON Web Tokens). These are cryptographically-signed tokens, issued by the control plane of your cluster, that let anyone in the world understand who is calling when your workload uses them. In Kubernetes 1.37, the foundations of a new built-in production identity technology have gone GA. Pod Certificates (and the closely-associated Cluster Trust Bundles) build X.509 certificate issuance for TLS and mTLS directly into core Kubernetes. Why? Service account JWTs have a lot going for them: They are built directly into Kubelet, and work pretty magically. They are written to your workload container's filesystem before your workload starts up, and automatically kept up to date. The issuance system follows least-privilege principles; the node restriction admission plugin ensures that tokens can only be requested by the Kubelet that is actually currently running your pod. They can be federated, allowing you to use them to authenticate to other systems outside of Kubernetes. Service account JWTs underpin the pod-to-cloud authentication store for all of the largest cloud providers, and have widespread support across many additional services and software packages. If it can understand JWTs, you can authenticate to it with a service account token. However, service account JWTs have one big downside -- they are bearer tokens. With bearer tokens, if you have the token, then you are the identity asserted by the token. And since you necessarily have to hand copies of the J ## Vercel CLI expands commands for DNS, domains, and projects DevFeed: [Vercel CLI expands commands for DNS, domains, and projects]() Original publisher: [Read original article]() Author: Melkey Moksyakov Published: 2026-08-28T00:00:00Z Content type: release Language: en Sources: [Vercel News]() Topics: [Vercel](), [Command-line interface](), [Terminal](), [API](), [dashboards](), [observability](), [JSON]() Tags: [agents](), [api](), [cli](), [configuration](), [dns](), [json](), [observability](), [projects](), [terminal](), [update](), [vercel](), [web]() ### AI overview Vercel CLI adds commands for managing DNS records, Vercel domains, project state, observability settings, and project members.
