June 7, 2024Looking for an API testing tool like Thunder Client, Postman, or REST API? 🔥 Give ToastBook a try! 🛠️ Easy to use, locally stores data 🗂️, and perfect for sharing files effortlessly. 🎉
Quite happy with Bruno, really have no interest in paywalled closed source. Anyone who’s had to move from postman to insomnia to thunder is getting a little cheesed off with open source turning into paid not so much source. This is not complex, it’s simply sending requests to a server and returning the response, you can do it from the command line easy enough.

November 7, 2024How is a sample API different from a mock API?
Mock APIs return predictable, static responses. Sample APIs simulate real conditions, slowdowns, errors, authentication, and multi-step logic.

Web API Sample Endpoints to Practice Monitoring & Testing
What is a Web API sample?
A Web API sample is a real, functional endpoint used for testing API behavior; latency, errors, JSON payloads, and workflows. Unlike mock APIs, sample APIs behave closer to production and are ideal for monitoring practice.

Is there a mock or sandbox payments API for testing?
Yes. ReqRes includes a simulated payments API that models the full payment lifecycle, including payment intents, confirmations, 3DS, card declines, refunds, webhooks, and idempotency, using test tokens with no real money involved. It lets agents and apps practice payment flows safely. It is not affiliated with any payment provider.

November 27, 2025 - These tools provide the instant, predictable endpoints needed to build, test, and iterate without dependencies. Whether you're a frontend developer building a UI prototype, a QA engineer designing failure scenarios, or a product team creating a proof-of-concept, the right mock or sample API is critical. A simple, static data provider like JSONPlaceholder might be perfect for quickly scaffolding a user list, while a more dynamic service like httpbin is essential for simulating complex network conditions and error states.

API Testing Examples: Real API Calls You Can Run Today
November 12, 2025 - Reading about API testing and running one are two different skills. You can know exactly what a status code means and still freeze the first time you have to write an actual request against a login endpoint. This guide skips the theory and goes straight to examples: real APIs you use every day, live cURL commands you can run right now, sample test cases by category, and the sandboxes professional testers use before a real API even exists.

Web API Sample Endpoints to Practice Monitoring & Testing
July 2, 2026 - The sample endpoints below aren’t designed to be “hello world” demos. They’re crafted to behave like real production APIs; sometimes fast, sometimes slow, sometimes incorrect, so you can validate how well your monitoring system responds to the unpredictable nature of distributed systems. Each endpoint includes the type of monitoring behavior it helps test, and what failures you should expect to uncover. A minimal endpoint designed for uptime checks and fast alerting.

r/QualityAssurance on Reddit: Can anyone recommend an open API for testing purposes?
October 6, 2022 -
The title more or less, at the moment I am learning rest sharp, but I have not found a decent open API for writing tests, something that isn't too easy nor too difficult.
Preferably with some POST and GET methods, so I can write tests for getting data I posted.
Also if anyone can link me a example of how to develop a API testing framework, how to order namespaces any such :)
Thanks in advance.
