Mock sample for your project: KeyServ API

The Internet of Things for Everyone
The Adafruit IO HTTP API provides access to your Adafruit IO data from any programming language or hardware environment that can speak HTTP. The easiest way to get started is with an Adafruit IO learn guide and a simple Internet of Things capable device like the Feather Huzzah.
This API documentation is hosted on GitHub Pages and is available at https://github.com/adafruit/io-api. For questions or comments visit the Adafruit IO Forums or the adafruit-io channel on the Adafruit Discord server.
Authentication
Authentication for every API request happens through the X-AIO-Key header or query parameter and your IO API key. A simple cURL request to get all available feeds for a user with the username "iousername" and the key "iokey_12345" could look like this:
$ curl -H "X-AIO-Key: iokey12345" https://io.adafruit.com/api/v2/io_username/feeds
Or like this:
$ curl "https://io.adafruit.com/api/v2/iousername/feeds?X-AIO-Key=iokey_12345
Using the node.js request library, IO HTTP requests are as easy as:

This document describes the Intellifi Brain
Web API specification using the OpenAPI specification.
The Brain Web API is a RESTful API that allows you to interact with the
Intellifi devices and
services in a powerful and simple way. Our end-to-end solution allows you to
localize your items/assets based on technologies such as RFID and Bluetooth.
Try it out!
The API can be tried out and tested using the 'api-doc/tryitout' endpoint on this site.
This UI allows anyone to visualize and interact with the API’s resources without having any of the implementation logic in place.
It’s automatically generated from this Specification, with the visual documentation making it easy for back end implementation and client side consumption.
Authentication
Applications are required to provide some form of authentication to the API
for every secured endpoint. The Brain offers two forms of authentication.
API key (Via an HTTP request header or URL parameter)
Session cookie

Welcome to the Netatmo swagger on-line documentation !
This site is a complement to the official Netatmo developper documentation using swagger to bring interactivity and easy testing of requests with the "try it" button (authenticate with the authorization code OAuth2 flow by clicking the authenticate button in the methods). You can find the source code for this site can be found in the project netatmo-swagger-ui. You can also use the online swagger declaration file to generate code or static documentation (see netatmo-swagger-api).
