"Since written language only emerged about 5,000 years ago — recent in evolutionary terms — our brains haven’t had time to evolve dedicated reading circuits. Instead, we’ve repurposed the neural networks that once kept our ancestors alive in the wild."

Markdown vs HTML. Every time we go from a semantically dense to a semantically sparse format, we lose. Even more today where less tokens from the same content is way better. I can understand we need a better markdown. I can't understand we should replace it with HTML.

"AX, or agentic experience, is the measure of how easily an AI agent can understand and use an API. If your API offers a good AX, AI agents will be able to find it and use it easily." apichangelog.substack.com/p/why-ax-is-...

How does one engage with the arduous and existential task of long-term thinking? How can we work on civilizational durability without dissolving into ambiguities? @protocolized.bsky.social + @denisehearn.bsky.social explain how we're putting long-term thinking into practice with Long Now Labs ->

Excited to share that I’ll be at apidays NYC next week! I'll be helping MC tracks across both days. Who's gonna be around? www.apidays.global/events/new-y...

A very early exploration on the taxonomy of API operations, where I identify eight operation categories. notes.brunopedro.com/2026/05/05/2...

"DeepSeek effectively broke the pricing floor for frontier models. By slashing V4-Pro prices by 75%, the company has brought cached input prices down to an unprecedented $0.0037 per million tokens." apichangelog.substack.com/p/2026-18/

"Integrating with multiple APIs feels like maintenance hell. The more APIs you integrate with, the higher the chances of something bad happening are. Every time one of the APIs you integrate with changes, you need to change something on your side." apichangelog.substack.com/p/workflows-...

What does long-term thinking look like in practice? Introducing Long Now Labs, a collaborative space to test, prototype, and build long-term tools. If you're a designer, researcher, or technologist interested in the deep future, we want to hear from you. Submissions are open: longnow.org/labs/001/

"Traditional API pricing is built for humans, not machines. Most monetization strategies use tiers that offer a fixed amount of API consumption. How can you fix this?" apichangelog.substack.com/p/the-rise-o...

NEW POST Thoughtworks internal IT use a workflow for agentic programming called Structured-Prompt-Driven Development (SPDD). Wei Zhang and Jessie Jie Xia describe how this works with a simple example with details in a github project. martinfowler.com/articles/str...

"Storing API Keys, or any other sensitive information, on a git repository is something to be avoided at all costs. Even if the repository is private, you should not see it as a safe place to store sensitive information." medium.com/free-code-ca...

Unblock your front-end team. Start building before the backend is done.

"Agentic experience is the new developer experience. It’s not enough that your API is well-documented and easy to integrate with. And it’s also not enough that it’s well-designed so that its capabilities benefit end users." apichangelog.substack.com/p/why-ax-is-...

Have you heard of MDX? Are you using it? "Markdown is not enough. At least, not if what you want is to offer interactivity or personalization." apichangelog.substack.com/p/making-api...

Happy birthday @inkandswitch.com! Ink & Switch is now 10 years old, and is celebrating with a piece of interactive digital art on www.inkandswitch.com – have a play with it :)

"Trying to authorize agents to use your API using technology meant for humans feels like a dead end. Many of the interactions we take for granted are simply not viable when you remove the person from the loop." apichangelog.substack.com/p/four-agent...

"The latest shift in the API landscape signals a profound transformation toward AI-native infrastructure, as I could see from last week’s news, where the traditional boundaries between human developers and autonomous agents are rapidly dissolving." apichangelog.substack.com/p/2026-16

It's 2026, and I can't find any interesting OpenAPI-defined public APIs I can use freely for testing purposes. Yes, there are free, public test APIs, but the ones I found don't have an OpenAPI document.

The technical choices you make directly constrain the UI and UX that developers can provide to their customers.

"APIs that go rogue are almost impossible to tame. While managing the APIs you already know can sometimes be challenging, imagine the difficulty of controlling the ones you don't even know exist." apichangelog.substack.com/p/orphan-sha...

Don't let your API become a zombie. Planning for its sunset from day one is essential to avoid resource drains and security risks.

"we needed more than could be expressed in an OpenAPI schema. OpenAPI schemas describe REST APIs, but we have interactive CLI commands that involve multiple actions" notes.brunopedro.com/2026/04/14/2...

" Where do I back it up? Can I delete it, can I duplicate it, et cetera. There's a version of that for nations. And I think that's a little bit what Europe is grappling with right now." @adamwiggins.com

Stop building in the dark and start listening to what your API is actually telling you.

"Agent Auth attempts to make agent authorization fully autonomous. By shifting to a protocol-driven identity model, this approach allows agents to prove their identity and obtain scoped permissions programmatically." apichangelog.substack.com/p/four-agent...

"The Agentic Authorization OAuth 2.1 Extension is an IETF draft created in May 2025. It’s now in its version 01 and provides a solution where AI agents can identify their users and, in turn, use their identification to obtain OAuth access tokens." apichangelog.substack.com/p/four-agent...

"A workflow that can't be executed remotely feels like a loss of potential. I mean, you can still trigger it manually, or even execute it periodically. However, there's no way for it to receive programmatic requests from the outside world." apichangelog.substack.com/p/exposing-w...

"APIs are no longer just passive data pipes, but active, auditable, and intelligent frameworks that bridge the gap between human intent and machine execution." Thanks to @jentic.bsky.social for their support, helping keep an independent API publication alive. apichangelog.substack.com/p/2026-14
