The spoonacular Nutrition, Recipe, and Food API allows you to access over 380,000 recipes, thousands of ingredients, 80,000 food products, and 100,000 menu items. Our food ontology and semantic recipe search engine makes it possible to search for recipes using natural language queries, such as "gluten free brownies without sugar" or "low fat vegan cupcakes." You can automatically calculate the nutritional information for any recipe, analyze recipe costs, visualize ingredient lists, find recipes for what's in your fridge, find recipes based on special diets, nutritional requirements, or favorite ingredients, classify recipes into types and cuisines, convert ingredient amounts, or even compute an entire meal plan. With our powerful API, you can create many kinds of food and especially nutrition apps.
Special diets/dietary requirements currently available include: vegan, vegetarian, pescetarian, gluten free, grain free, dairy free, high protein, whole 30, low sodium, low carb, Paleo, ketogenic, FODMAP, and Primal.

Description of Instagram RESTful API.
Current limitations:
Instagram service does not support cross origin headers
for security reasons, therefore it is not possible to use Swagger UI and make API calls directly from browser.
Modification API requests (POST, DELETE) require additional security scopes
that are available for Apps created on or after Nov 17, 2015 and
started in Sandbox Mode.
Consider the Instagram limitations for API calls that depends on App Mode.
Warning: For Apps created on or after Nov 17, 2015 API responses
containing media objects no longer return the data field in comments and likes nodes.

Options for authorizing API Calls
Using Client ID directly
You can directly connect to our API using your client ID by sending it as a GET query parameter. This option is simple (no need for oAuth) but it should be used only in case the Client ID is not exposed publicly.
GET https://api.ritekit.com/v1/stats/multiple-hashtags?tags=php&client_id=292c6912e7710c838347ae178b4a

API Reference: The StatSocial API is organized around REST. Our API is designed to have predictable, resource-oriented URLs and to use HTTP response codes to indicate API errors. We use built-in HTTP features, like HTTP authentication and HTTP verbs, which can be understood by off-the-shelf HTTP clients, and we support cross-origin resource sharing to allow you to interact securely with our API from a client-side web application (remember that you should never expose your secret API key in any public website's client-side code). JSON will be returned in all responses from the API, including errors (though if you're using API bindings, we will convert the response to the appropriate language-specific object). Contact [email protected] to obtain a test API key

This page contains the documentation on how to use Discourse through API calls.
> Note: For any endpoints not listed you can follow the
reverse engineer the Discourse API
guide to figure out how to use an API endpoint.
Request Content-Type
The Content-Type for POST and PUT requests can be set to application/x-www-form-urlencoded,
multipart/form-data, or application/json.
Endpoint Names and Response Content-Type
Most API endpoints provide the same content as their HTML counterparts. For example
the URL /categories serves a list of categories, the /categories.json API provides the
same information in JSON format.
Instead of sending API requests to /categories.json you may also send them to /categories
and add an Accept: application/json header to the request to get the JSON response.
Sending requests with the Accept header is necessary if you want to use URLs
for related endpoints returned by the API, such as pagination URLs.
These URLs are returned without the .json prefix so you need to add the header in
order to get the correct response format.
Authentication
Some endpoints do not require any authentication, pretty much anything else will
require you to be authenticated.
To become authenticated you will need to create an API Key from the admin panel.
Once you have your API Key you can pass it in along with your API Username
as an HTTP header like this:
Boolean values
If an endpoint accepts a boolean be sure to specify it as a lowercase
true or false value unless noted otherwise.
