Open API spec for Ideal Postcodes API (api.ideal-postcodes.co.uk)

The GeoDB API focuses on getting global city and region data. Easily obtain country, region, and city data for use
in your apps!
Filter cities by name prefix, country, location, time-zone, and even minimum population.
Sort cities by name, country code, elevation, and population - or any combination of these.
Get all country regions. Get all cities in a given region.
Display results in multiple languages. RESTful API adheres to industry best-practices, including
HATEOAS-style links to facilitate paging results.
Backed by cloud-based load-balanced infrastructure for resiliency and performance!
Data is periodically refreshed from GeoNames and WikiData.
Notes:
Since the database is periodically updated, this may very rarely result in certain cities
being marked deleted (e.g., duplicates removed). By default, endpoints returning city data will exclude
cities marked deleted. However, in the unlikely event that this occurs while your app is paging through a set
of affected results - and you care about the paged results suddenly changing underneath - specify
includeDeleted=SINCEYESTERDAY (or SINCELAST_WEEK if you're really paranoid!).

Drive your app to success with Lyft's API

The Miataru API is very simple and straight forward. Generally you're posting (HTTP POST) a JSON formatted request to a service method locations and you get back a JSON formatted answer. Please take into consideration that this has the request-for-comment status and that it can change while there's work done on client and server applications. Versioning therefore is done by prepending the version number - /v1/ for version 1 - to the method call.
