An API, or Application Programming Interface, is not a physical entity you can see or touch—it is a set of rules and protocols that allows different software systems to communicate with each other. Think of it as a bridge that enables apps, servers, or platforms to interact efficiently and securely.
APIs typically reside on web servers and are accessed over the internet. For example, when a developer says “Where is the API?” they’re usually referring to the endpoint URL that allows access to specific functions or data. This might look something like:
From a technical perspective, APIs are hosted on backend servers that process requests and deliver responses, often in JSON or XML format. These servers can be on cloud platforms like AWS, Google Cloud, or Azure. They may serve public users, or be protected behind authentication mechanisms for private access.
In practical use, an API could be a weather service, a payment gateway, or a social media integration—where your application “calls” the API to get information or trigger an action.
If you're trying to locate a specific API:
Check the developer documentation of the service you're using.
Look for the base URL and available endpoints.
Understand what keys or tokens are required for access.
In short, the API “lives” online—on a server—ready to be called by any compatible application that knows how to speak its language.
API 6D exceeds API 598 in both pressure and duration.
MySQL is not an API MySQL is a database where you store data. An API is how you request information from another website.
The Java API is the API for the main Java Library.
API X70 is one of line pipe grade family define by API 5L specification
The pressure test for API 598 is slightly less pressure and less duration than API 6D. API 6D is specifically for pipeline valves.
API manufacturing is manufacturing of active pharmaceutical ingredients.

A payment API is a kind of API (application programming interface) that resolves credit card processing and other commerce issues.
The main difference between API 600 and API 503 valves is their port diameter. Also, the pressure testing between the two is different as well.
To access and use the DOI API for retrieving digital object identifiers, you can register for an account with a DOI registration agency like CrossRef or DataCite. Once you have an account, you can obtain an API key to access the API. You can then use the API to search for and retrieve DOIs by sending requests with your API key.
An API unit is a way to measure the consumption and allocation of resources in an API-based system. It typically represents a quantum of API usage, such as the number of requests, data transferred, or computational resources utilized by an application. Organizations often use API units to track usage, monitor performance, and manage costs related to their API services.
Google Chart API was created in 2007.
