We 💚 Git-driven API clients
Git-driven API workflows are finding their footing with API dev teams, improving devX and repeatability. Also in this issue: MCP is just an API, Go-Fault, the very basics of HTTP Requests in node, and Speakeasy's Agent Skills
As agents have made their way into my workflow at work, OpenAPI Spec Rules and Git-native API clients have become my most sought-after tools. Git-native clients are an easy win because they keep everything in the same repo, giving the agent more content. I get the most out of agents in projects with well-defined patterns, linting and tests. It becomes quite enjoyable to chat with the agent about changes, then see the OpenAPI spec update, lint it against the rules, confirm the output, and then watch the code change.
If you slept on OpenAPI Rules and Git-native API clients, it's time to pick them up. Bruno has been my go-to client for a while now.

Overlay
Version 1.1.0 of the Overlay Specification launched at the start of 2026, bringing several new features. The copy property for the Action Object allows any element in the spec to be copied or moved in the OpenAPI document. You can now also update primitive values such as strings, integers, and others directly, rather than the parent object, making Overlay documents easier to manage. Check out the full spec for all the details.
Go-Fault
A nifty Go middleware package that makes it super easy to reject incoming HTTP requests and respond with an HTTP error. Super handy for testing failure scenarios with its three types of injectors SlowInjector, ErrorInjector, and RejectInjector.
How to make an HTTP request in Node.js
There are so many ways to make an HTTP request in Node; thankfully, Luciano has put together a detailed walkthrough covering everything from basic requests to timeouts, streaming, form data, and more.
JSON Schema as the Foundation for API Design
Kin Lane talks with David Viesack about JSON Schema and how great it makes working with API specifications. The part that caught my eye was David's discussion of a tool they built that extracts schemas from OpenAPI documents, allowing testing of request bodies without the full API structure. Definitely worth reading in full.
MCP Is Just an API
Bruno Pedro sits down with Emmanuel Paraskakis at API Days to talk through all the chatter on MCP making APIs irrelevant. Their main takeaway is that a good OpenAPI spec leads to a great MCP server with a good task success rate for the LLM. Watch the full video for all the details.

Alternatives to Postman
On the off-chance you haven't seen our rundown of various API Clients to use as an alternative to postman, this one is worth a read through. Our love for Bruno and the new class of git-driven API Clients started here - maybe yours will too!

OpenAPI and SDK Agent Skills
Sagar Batchu, the co-founder of Speakeasy (one of our sponsors), posted about the release of Agent skills for OpenAPI and SDK generation. I have been really digging some of the released vibe-skills for helping colleges unfamiliar with libraries like TanStack Router, so it's great to see some skills around the OpenAPI Spec now.
