Mock sample for your project: Interzoid Get City Match Similarity Key API

This API provides the two-letter state abbreviation (or the province abbreviation for Canada) for the purposes of standardizing state name data, improving query results, analytics, and data merging.

This API provides a similarity key used to match with other similar country 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 algorithmically generated similarity key rather than the data itself.

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.

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

This API provides a standard for country name for the purposes of standardizing country name data, improving query results, analytics, and data merging.

This API provides a timed, browser-simulated page load function (or a measured API call) from the specified geography using a server from that geography.

This API provides validation information for email addresses to aid in deliverability. Syntax, existence of mail servers, and other tests are run to ensure delivery. Additional demographics are provided for the email address as well, including identifying generic, vulgar, education, government, or other entity type email addresses.

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 detailed information for a given zip code, including city, state, latitude, longitude, area size, and various population demographics.

This API provides a similarity key used to match with other similar full name data when data fields are parsed into first name and last name components, 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 separate fields. Use the Full Name Similarity Key API for first and last name data that are in the same field.

This API enables you to convert an amount of one currency into another currency using current foreign exchange rates.

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

This API provides a similarity key used to match with other similar city 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 algorithmically generated similarity key rather than the data itself.

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.
