Mock sample for your project: VictorOps API

Airbyte Configuration API
https://airbyte.io.
This API is a collection of HTTP RPC-style methods. While it is not a REST API, those familiar with REST should find the conventions of this API recognizable.
Here are some conventions that this API follows:
All endpoints are http POST methods.
All endpoints accept data via application/json request bodies. The API does not accept any data via query params.
The naming convention for endpoints is: localhost:8000/{VERSION}/{METHODFAMILY}/{METHODNAME} e.g. localhost:8000/v1/connections/create.
For all update methods, the whole object must be passed in, even the fields that did not change.
Change Management:
The major version of the API endpoint can be determined / specified in the URL localhost:8080/v1/connections/create
Minor version bumps will be invisible to the end user. The user cannot specify minor versions in requests.
All backwards incompatible changes will happen in major version bumps. We will not make backwards incompatible changes in minor version bumps. Examples of non-breaking changes (includes but not limited to...):
Adding fields to request or response bodies.
Adding new HTTP endpoints.

This API provides a similarity key used to match with other similar full name data, including for purposes of deduplication, fuzzy matching, or merging of datasets. A much higher match rate will be achieved by matching on the similarity key rather than the data itself. This API is for full name data where first and last name are in the same field. Use the Full Name Parsed Similarity Key API for first and last name data that are in separate fields.

This API provides area code information for a given telephone number.

This API retrieves the current time for a city or geographic location around the globe.

The Local Search client lets you send a search query to Bing and get back search results that include local businesses such as restaurants, hotels, retail stores, or other local businesses. The query can specify the name of the local business or it can ask for a list (for example, restaurants near me).

A simple HTTP Request & Response Service. Run locally: $ docker run -p 80:80 kennethreitz/httpbin

This API provides a similarity key used to match with other similar street address data, including for purposes of deduplication, fuzzy matching, or merging of datasets. A much higher match rate will be achieved by matching on the algorithmically generated similarity key rather than the data itself.
