Taking a fresh look at what matters when it comes my online presence these days so that I can focus on the important things. buttondown.com/apievangelis...

"Behind the scenes, MCP uses JSON-RPC, which, by definition, exposes operations, not resources or data like other API styles do. Since workflows are sequences of operations, it makes total sense to use MCP tools inside them. Is that already possible?" apichangelog.substack.com/p/using-mcp-...

This is the frontline I will be using to guide my governance of AI integration into the enterprise. insnerds.com/news/insurer...

I am doing deep work on my definition of a capability right now, balancing across the areas that matter when it comes to accomplishing what I envision. buttondown.com/apievangelis...

I separate API usage into internal, 1st-party, and 3rd-party APIs because it emphasizes the two most important aspects 1) control, 2) firewall perimeter. However 75% of people I share this with struggle with word 1st-party, which I find interesting because they are fine with 3rd-party.

Responding to something I hear a lot about the state of the web & APIs. apievangelist.com/2025/11/17/t...

I am going through the vocabulary and the schema looking for which of the screws, knobs, and levers can be turned to achieve business alignment this week. - buttondown.com/apievangelis...

Sitting down with the Microcks team this week at #kubecon to plan our Naftiko 3rd-party SaaS sandboxes got me thinking about how domain and context will shape the next generation of API discovery. - apievangelist.com/2025/11/13/a...

Thinking about the economics of different protocols and JSON-RPC was up next. apievangelist.com/2025/11/12/o...

🪄 KubeCon is full of surprises! We're excited to share that we met @kinlane.bsky.social, the @apievangelist.com, today. He will be joining the Microcks maintainers tomorrow at our Project Kiosk 10A in the Project Pavilion zone at #KubeCon + #CloudNativeCon NA 🚀 We can't wait to see you there! 🙌

"Trust is a key factor behind deciding which API specification format you should use. Should you define your API using AsyncAPI, OpenAPI, Smithy, or TypeSpec, just to name a few formats?" apichangelog.substack.com/p/the-hidden...

"I recently participated in a project related to the exchange of information with business partners. One of the goals was to allow external entities to share information with my organization. The second goal was to allow the same thing but in reverse." apichangelog.substack.com/p/documentin...

Gathering some of the patterns out there for augmenting OpenAPI with what you need for MCP generation using OAS extensions. apievangelist.com/2025/11/04/o...

The city business and politics of rate limits impact on your subscription -- your Citibike costs more because the city just limited your speed to 15 MPH. ;-)

I have been struggling to adequately explain to investors, advisors, and customers about how a schema, rules, and policy driven approach to consuming APIs provides a competitive edge. apievangelist.com/2025/10/28/s...

I've heard it for years - that as a startup you shouldn't be consulting. I've long felt this was not practical advice, so I set out to refine my plan so I don't lose the fight this round. apievangelist.com/2025/10/23/a...

"Nothing can replace the interaction with a real API. Not until you connect with a simulation of the API, that is. It's as if you were making requests to the real API." apichangelog.substack.com/p/api-mock-v...

I had totally missed that @microcks.io offers data persistence since August 2024: notes.brunopedro.com/2025/10/22/2...

"(...) I feel an API is not a good candidate [for a value unit]. To me, a good API platform value unit is an ■■■■■■■■■." apichangelog.substack.com/p/how-to-cre...

Drift is ubiquitous because we operate in difference scopes and lack a common vocabulary. apievangelist.com/2025/10/15/w...

I am working through some thoughts after getting push back around using Domain-Driven Design in API integration and consumption conversations. apievangelist.com/2025/10/14/a...

"Most elements you create during API design are wasted. If they’re not validated by stakeholders, they end up being replaced with new ideas. What if I tell you that API prototyping can be an incremental process?" apichangelog.substack.com/p/just-in-ti...

I keep getting asked what is coming to API integration and automation in this AI moment, and I don't normally deal in telling stories about what is around the corner, but figured I would share this bit. apievangelist.com/2025/10/07/h...

Interesting offering I am evaluating, "The programmable automation layer for your API schema lifecycle. Unifying discovery, validation, documentation, and AI agent automations. Offline-first and real-time." appear.sh

If I can't find an icon or link to GitHub on your home page in header or footer it is unlikely I will be concerned with your developer tooling.

Doing a quick "diff" between FinOps and what I've known from the other side of the hustle with API management and monetization -- two sides of the same coin. buttondown.com/apievangelis...

Getting at the reasons why we are standardizing APIs. apievangelist.com/2025/09/26/t...

Most people I am interviewing about API integration & automation do not have a lot of control when it comes to “doing the right thing” with APIs, or whether they use AI or not. They are just being told they need to do something. I think the lack of control is where a lot of us miss the boat.

This weeks API Evangelist newsletter focuses in on automation in an attempt to clarify what we mean when we say agentic in service of automation. buttondown.com/apievangelis...

Can OpenAPI copy MCP and offer an official registry? Why hasn't this been done before? Here's a quick analysis of what happened to ProgrammableWeb, Postman Network, Mashape, and RapidAPI. notes.brunopedro.com/2025/09/16/2...
