Mock sample for your project: Marketcheck APIs

The Charity API allows third-party developers to search for and access details on supported charitable organizations.

The Account API gives sellers the ability to configure their eBay seller accounts, including the seller's policies (the Fulfillment Policy, Payment Policy, and Return Policy), opt in and out of eBay seller programs, configure sales tax tables, and get account information. For details on the availability of the methods in this API, see Account API requirements and restrictions.

A product library is a representation of all the items that can be
displayed, put in a shopping cart and sold to a customer. Items may be
either producs or discounts.
A product is a synthetic construct, wrapping one or more variants (which is
the actual item being sold) Variants expresses different variations of
properties such as for example price, size or color. A discount will reduce
the total amount charged in a shopping cart. It can be used per item line,
or on the whole cart. It may reduce the affected amount by a percentage, or
by a fixed amount.
Together, the above types of entities makes up a complete library. The
library can be fetched as a whole through the library endpoint, where each
consecutive change applied to the library is available. Once the full
library is retrieved, only later events needs to be fetched to keep the
client up to date with the server
All path patterns "/organizations/{organizationUuid}/" can be replaced
with "/organizations/self/" for convenience as all endpoints are for
authorized users.

The Metadata API has operations that retrieve configuration details pertaining to the different eBay marketplaces. In addition to marketplace information, the API also has operations that get information that helps sellers list items on eBay.

Just Eat API
Just Eat offers services for our various business partners and our consumer applications.
How you interact with the API depends on the services you wish to interact with.
Security
HTTPS
All api calls and callbacks require HTTPS. Your service will need a valid SSL certificate and be accessible via the standard SSL port (port 443).
Making an API request
Some API calls require an API key, to authenticate the partner calling the API.

This API allows 3rd party developers to translate item title, description, search query.

This API provides access to our Automotive Data. Use of this API is subject to our Terms of Service

If you signed up through RapidAPI make your test calls here
The general workflow is to: 1. Authenticate with your CIS Automotive API Keys to get a Json Web Token (JWT). Do not use RapidAPI keys.
Then use that token as an argument when calling other endpoints.
Equivalent HTTP GET and POST methods are available for some endpoints.
Endpoints may appear more than once on this page if they are associated with multiple tags. eg "Sales Data", "Premium", "Pro Plan or Greater" To see which endpoints are included in different
plans look under the "X Plan or Greater" tags for the respective plan name.
If you signed up for our API through RapidAPI you can make your test calls on their platform.
Your RapidAPI credentials will not work on this page. Do not use your RapidAPI keys on this page.
If you signed up with us and have an account, you must first authenticate with your API Keys
and retrieve a Json Web Token (JWT) from the /getToken endpoint to access the other endpoints.
Your JWT is a required argument to all endpoints.

Please make sure you use the correct version of the APIs for your use case. To find out the appropriate version, go to the API Docs drop down on the menu.

Use the Taxonomy API to discover the most appropriate eBay categories under which sellers can offer inventory items for sale, and the most likely categories under which buyers can browse or search for items to purchase. In addition, the Taxonomy API provides metadata about the required and recommended category aspects to include in listings, and also has two operations to retrieve parts compatibility information.
