Smartcar is the only car API built for developers, by developers.

Smartcar is the car API for mobility applications. We allow car sharing, auto insurance, fleet management, and EV charging applications to retrieve the location, odometer reading, EV battery level, and other information from vehicles across brands in a single integration.

Smartcar makes it easy to read vehicle data and send commands to vehicles of any brand using HTTP requests. The Smartcar API is organized around REST. We use built-in HTTP features like HTTP verbs and HTTP authentication so you can use any HTTP client. All responses are returned in standard JSON and are documented in our API reference.

All requests made to our API require an access token. Our API uses the OAuth2 authorization framework and provides a granular permissioning system that authorizes API endpoints based on user preferences. This allows applications to easily authorize and interact with vehicles through the Smartcar API.

The WordPress REST API provides an interface for applications to interact with your WordPress site by sending and receiving data as JSON

The WordPress REST API provides an interface for applications to interact with your WordPress site by sending and receiving data as JSON (JavaScript Object Notation) objects. It is the foundation of the WordPress Block Editor, and can likewise enable your theme, plugin or custom application to present new, powerful interfaces for managing and publishing your site content.

Using the WordPress REST API you can create a plugin to provide an entirely new admin experiences for WordPress, build a brand new interactive front-end experience, or bring your WordPress content into completely separate applications.

The REST API is a developer-oriented feature of WordPress. It provides data access to the content of your site, and implements the same authentication restrictions — content that is public on your site is generally publicly accessible via the REST API, while private content, password-protected content, internal users, custom post types, and metadata is only available with authentication or if you specifically set it to be so. If you are not a developer, the most important thing to understand about the API is that it enables the block editor and modern plugin interfaces without compromising the security or privacy of your site.
