    When automating business processes at work, I found it difficult and time-consuming to reverse engineer business systems' APIs. I often had to manually reverse engineer APIs using developer tools or settle for less optimal technologies such as Robotic Process Automation (RPA). Often, the issue is that it can be hard to resolve all the cookies, access tokens, and other elements required to successfully execute the requests. Manually trying to resolve these dependencies using developer tools is especially challenging with multiple requests where data is stored in JavaScript objects or HTML…

    Hey HN, It will be more of a "How I released my API without managing a website, servers, users, and payments. With 0$ up-front cost" Over the past year, I have come up with a plan of how I could release my own product without having to deal with managing users and/or dealing with payment processing. It is a 3 steps procedure: 1. Make an API that solves a problem 2. Deploy it with a serverless architecture 3. Distribute through an API Marketplace That took me about 2-3 days to develop an API using Flask, deploy it via Zappa on AWS, and release through RapidAPI. Source code of API:…

    Hey HN! We built a browser-based agent that runs inside an authenticated web app, watches how the app calls its own APIs, and automatically turns those into agent tools. You can think of it as an auto-generated MCP server that self-updates as the host app changes. The result is a skilled AI assistant that actually integrates deeply with any product (not just chat and RAG) with minimal effort. Check out these short demos below that show the agent in software you're probably familiar with: - Jira: https://demo.frigade.com/hn?skill=jira - Spotify:…

    Select anything on a website. If it is part of a table or a list, you get a URL which you can GET for a JSON representation of that list or table. Basically we are making an API for every website whether they like it or not.

    Hi guys, I've worked on several apps in the past couple of years, and found that it takes too much effort going from having an idea to building an app and having the world use it. I wanted a way to have an idea, turn it into a fully functional native app, and share it with the world, all in the next 5 minutes, as quick and as easy as writing a blog post. That's why I built Jason. Basically Jason lets you build a native interface to display and interact with any data format (csv, rss, html, json), any website, any API in any way you want, simply by writing a JSON markup and loading it.…

    Hi HN! We built Zalor. It turns an OpenAPI spec into an MCP server, so you can make your APIs callable by Claude or ChatGPT without writing any code. Here's a list of specs you can try: https://github.com/ZalorAI/test-data/tree/main/openapi, but feel free to use your own. For background, MCP is a protocol that standardizes how you connect tools to AI assistants. We're both engineers at large software companies, and when we worked on MCP integrations we saw how long setup took and how often the spec was changing. So we built a platform to handle the MCP…

    Hi All, API integration often cycles in repetitive use cases, API specs, Libraries/SDKs, developer context & tech support. We are building a desktop app that lets SaaS API sellers design their API integration flow and lets their customer integrate APIs in seconds. 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…
