    tl;dr we released openapi.security, an online tool that performs a dozen of security tests on any given openapi/swagger-based API, with no signup or email required. You can try it here: https://openapi.security My team at Escape (YC W23) is mainly focused on securing GraphQL APIs. For this, we developed a new approach called Feedback driven API Exploration. Basically, we infer the right security tests cases to run using the specification and a carefully crafted in house graph traversal algorithm. (It's a bit long to describe here but we published a more in depth explanation of…

    Hi, this is Mish and Sebastian. We are working on Step CI - a fully automated API testing platform for developers. Step CI works programming-language independent and for different API paradigms (REST, GraphQL, XML). Our CLI and test runner are available on GitHub (https://github.com/stepci) under the MPLv2 license. Since our last launch, Step CI is now able to generate automated tests for your API based on your OpenAPI (Swagger) spec. This saves you a lot of time as you never have to write and maintain your tests again! We would like to invite you to try our tool and give us…

    Hey HN! We've developed OpenAPI AutoSpec, a tool for automatically generating OpenAPI specifications from localhost network traffic. It’s designed to simplify the creation of API documentation by just using your website or service, especially useful when you're pressed for time. Documenting endpoints one by one sucks. This project originated from us needing it at our past jobs when building 3rd-party integrations. It acts as a local server proxy that listens to your application’s HTTP traffic and automatically translates this into OpenAPI 3.0 specs, documenting endpoints, requests, and…

    Hey there HN! I just wrapped up an all-day documentation spree for Instant API, a JavaScript framework for easily building web APIs that implements type safety at the HTTP interface. It uses a function-as-a-service approach combined with a slightly modified JSDoc spec to automatically enforce parameter and schema validation before HTTP requests make it through to your code. You just write comments above your endpoint functions and voila, enforced type safety contracts between your API endpoints and your developers. OpenAPI specifications are generated automatically as a byproduct of simply…

    Hey HN! Jaka here, solo founder of Assertly (https://www.assertly.com). Assertly is a monitoring tool for continuous infosec, IT, compliance and DevOps regression testing. It enables teams to automate periodic checks using JavaScript. Before Assertly, I was the CTO of Celtra (https://celtra.com), a B2B SaaS company, for over 10 years, from “git init” to 250 people and the company’s sale to private equity. I was primarily responsible for product strategy, engineering, QA, DevOps, but also for IT and InfoSec. I found that ensuring security, integrity, privacy, and…

    api2ai parses OpenAPI Spec to generate an agent that can make API calls. For context, I recently need to explore a handful of API suites and thought LLMs can help expedite this process. After some digging, I found OpenAPI Specs are perfect fit for function calling. Based on a text prompt, api2ai can select the right endpoint and properly parse request params and make api calls. It also handles authentication, currently it supports basic auth, api keys, and bearer token schemes. The tool has helped me explore and see APIs in action without a deep dive into the docs or using postman. It’s open…
