Mock sample for your project: DaniWeb Connect 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 detailed information for a given zip code, including city, state, latitude, longitude, area size, and various population demographics.

The CircleCI API is a RESTful, fully-featured API that allows you to do almost anything in CircleCI.
You can access all information and trigger all actions.
The only thing we don’t provide access to is billing functions, which must be done from the CircleCI web UI.
