"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

What actually goes into building enterprise-grade AI agents? My latest for @infoworld.bsky.social explores the emerging best practices behind agentic systems: www.infoworld.com/article/4154...

Big milestone for #Arazzo 1.1 - #AsyncAPI support has been merged into the release candidate. Arazzo will soon span @openapis.org and AsyncAPI. One workflow language for multiple API styles. Huge thanks to the community. Just 136 review conversations over 7 months! github.com/OAI/Arazzo-S...

How do we bring determinism to AI systems that struggle with context and consistency? The answer lies in well-defined, machine-readable workflows, as Frank Kilcommins explains.

Signal #1 in The Weekly Signal series: Description Coverage. Your #API may be perfectly valid. It may also be almost useless to an AI agent. An agent reads your #OpenAPI Description. What it finds there is what it knows. Nothing more. Three APIs. Very different results. 👇

Have you got a problem? An API problem? A generic 400 Bad Request helps no one, not developers, not AI agents. #RFC9457 fixes this. We use it across our @jentic.bsky.social #APIs and just open-sourced reusable schemas + Python/TypeScript packages. #Apache2.0 github.com/jentic/api-problem-details

#LLMs figure things out. But for known capabilities, don't leave business logic to chance. #Arazzo codifies exactly what #agents should do: open standard, precise execution, no vendor lock-in. Discoverability without determinism is just controlled chaos. 👉 nordicapis.com/why-ai-agent... #APIs

"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...

Agents are getting more capable. The question now: does it work correctly, safely, predictably — every time? #AgentSkills, #MCP, #Arazzo. Three approaches at different points on the flexibility-to-control spectrum. Join Erik and I April 22nd to learn more. Register 👉 jentic.com/webinar/agen...

"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

Your AI agent nearly gets the API workflow right. Nearly. Vague API docs = wrong tool calls, bad arguments, silent failures. Arazzo is the open standard giving agents deterministic, step-by-step execution so "nearly right" becomes "always right." Watch the full talk 👇 youtu.be/XjbsAdREHxA

#Arazzo Editor is live! Build #API workflows with form-based editing + live diagrams. No YAML required (unless you want it). Below, I cover why tooling matters for standards, and how Arazzo fits in the agent-ready orchestration picture. jentic.com/blog/arazzo-editor #OpenAPI @jentic.bsky.social

Jentic Mini: open-source API execution layer built by OpenClaw for OpenClaws https://github.com/jentic/jentic-mini/discussions/129 (https://news.ycombinator.com/item?id=47602193)

We had a great time hosting and helping 100+ people in Dublin to get set up on OpenClaw. Looking forward to the next one and getting even more people started on OpenClaw with Jentic Mini 🦞🔒

Dublin startup Jentic launches a free, open source permission firewall for OpenClaw and other AI agents, giving developers credential control, fine-grained permissions, and a single killswitch.

Universal agents are here, and #OpenClaw proves it. These agents eagerly want unfiltered direct access to #APIs. That changes what #API-First means. Can your APIs can be reasoned over by machines, not just called by them? Join our live session next week to learn how to prepare: shorturl.at/rQlc8

Looking forward to speaking at #DeveloperWeek this week (Feb 18th-20th), and participating in the first @openapis.org summit of 2026. “You may have #OpenAPI, but is it AI-Ready?” I'll be exploring what it means to prepare your APIs for agentic and AI-driven uses through 6 key dimensions.

Short walkthrough of our 𝗔𝗜‑𝗥𝗲𝗮𝗱𝗶𝗻𝗲𝘀𝘀 𝘀𝗰𝗼𝗿𝗲𝗰𝗮𝗿𝗱 and diagnostics for #APIs. Most APIs expect devs to fill in gaps in the #OpenAPI description. Expecting AI agents to do that safely is an operational risk. We score six dimensions to show where APIs break for AI consumers. Try at: jentic.com/scorecard

Great round‑up from 𝙏𝙝𝙚 𝘼𝙋𝙄 𝘾𝙝𝙖𝙣𝙜𝙚𝙡𝙤𝙜. The trend of #APIs as the enabling layer for #AI is clear, showing up in real‑time voice, messaging integrations, and driving standardization. @jentic.bsky.social is proud to sponsor and partner with @brunopedro.com. apichangelog.substack.com/p/2026-06

Most APIs are designed for humans, not machines. Here are six dimensions to ensure your systems are interpretable, safe and ready for AI integration. By @jentic.bsky.social Head of Enterprise Architecture @fkilcommins.bsky.social

First post of the year with @thenewstack.io . Having reviews 1000s of APIs, I outline why most APIs break down in AI systems and 6 practical dimensions for making APIs AI-ready. To get more ROI from agents, we have to solve integration (it's the execution layer!). thenewstack.io/why-most-api...

What if you could query the official MCP registry from inside the Arazzo Visual Editor? This demo shows how easy it is to find the Model Context Protocol (MCP) server you want to use on your Arazzo workflow. By using the official MCP registry, you can quickly find the MCP server you're looking for.

For folks straddling #API and #AI lands: we’ve shipped Jentic OpenAPI Tools to #PyPI. A Python toolkit for parsing, validating, and transforming #OpenAPI docs, built with a pluggable backend architecture and strong type safety. Check it out at: pypi.org/project/jent... @jentic.bsky.social

MCP is changing how we expose #APIs to AI agents but mapping tools 1:1 to endpoints is fragile. Context gets bloated. Orchestration gets baked-in. Interoperability gets lost. In my latest blog, I suggest pairing #Arazzo + #MCP to counteract the challenges above! 👉 smartbear.com/blog/from-en...

AI is evolving fast and structured, deterministic interfaces still matter. For agents to reason and act reliably, they need more than endpoints. They need well-designed API capabilities. I covered more on the topic below👇 smartbear.com/blog/why-api... #OpenAPI #AgenticWorkflows #MCP #Arazzo
