The American Petroleum Institute (API) is the only national trade association that represents all aspects of America’s oil and natural gas industry. Our more than 600 corporate members, from the largest major oil company to the smallest of independents, come from all segments of the industry.
API stands for Application Programming Interface. You can think of it as a common language that lets different software systems communicate smoothly, without needing to know how the other is built. More technically, an API is a set of rules and protocols that determine how one application can request data from another.
