   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…

   Nous – Open-Source Agent Framework with Autonomous, SWE Agents, WebUI▲155

   Hello HN! The day has finally come to stop adding features and start sharing what I've been building the last 5-6 months. It's a bit of CrewAI, OpenDevon, LangFuse/Cloud all in one, providing devs who prefer TypeScript an integrated framework thats provides a lot out of the box to start experimenting and building agents with. It started after peeking at the LangChain docs a few times and never liking the example code. I began experimenting with automating a simple Jira request from the engineering team to add an index to one of our Google Spanner databases (for context I'm the…

SaaS API companies (including our existing customers) resort to: 1. For API documentation - readme.io, Postman and Swagger (few use PDFs too.) 2. For Chat/Support/FAQ - Freshdesk/Zendesk/Calendly/Skype/Teamviewer 3. For Developer Context - IDEs for Android/iOS/JavaScript On top of these…

    ApiNotes▲3

    Hi HN I built ApiNotes Mock Server, a small tool that generates a live mock REST API from an OpenAPI (3.0/3.1) or Swagger 2.0 spec. The goal was to remove all friction when you just need a mock API quickly: No sign-up required to create an anonymous mock Supports paste, file upload, or URL fetch Produces a base URL + an auto-generated endpoints list Anonymous mocks currently expire after 72 hours (you can register to keep them / get higher limits) Link: https://apinotes.io/mock-server I’d love feedback on: What would make you trust a mock server like this for real…
