    Apidog▲570

    Development teams often struggle with using multiple tools like Postman and Swagger for API design, development, and testing. This fragmented approach leads to outdated API specs and chaotic collaboration. So we built Apidog: a single, unified API platform for team collaboration. It has a beautiful interface that makes it easy to create API spec, generate request data from API spec, validate responses, create mock data, orchestrate test scenarios, and publish API documentation. Apidog = Postman + Swagger + Mock + JMeter.

    YAML Studio▲7

    Hi HN I built YAML Studio, a visual editor that helps you design complex OpenAPI specs without hand-writing YAML or dealing with $ref headaches. It's a drag-and-drop, form-based tool that generates clean OpenAPI 3.0/3.1 YAML — useful for devs, PMs, and tech writers who want to collaborate on API design without needing deep spec knowledge. Why I built this: I’ve spent countless hours manually writing and debugging OpenAPI files — breaking things with a bad indent or misused $ref. Existing tools like Swagger Editor are great, but still very code-centric. I wanted something more intuitive,…

    Agents.json – OpenAPI Specification for LLMs▲212

    Hey HN, we’re building an open specification that lets agents discover and invoke APIs with natural language, built on the OpenAPI standard. agents.json clearly defines the contract between LLMs and API as a standard that's open, observable, and replicable. Here’s a walkthrough of how it works: https://youtu.be/kby2Wdt2Dtk?si=59xGCDy48Zzwr7ND. There’s 2 parts to this: 1. An agents.json file describes how to link API calls together into outcome-based tools for LLMs. This file sits alongside an OpenAPI file. 2. The agents.json SDK loads agents.json files as tools for an LLM that…
