Abstract
An API gateway designed to process a high volume of API requests for data and services where relatively large payloads are returned to the requester. The API gateway includes an “on-line” component that, for each API request, examines information in the request to increment an API usage count by API ID and product key. The usage information is periodically pushed to an outbound message queue, where it is later populated in a database. An “off-line” component determines if a customer has exceeded its predetermined quota based on the information in the database. This determination is pushed to another message queue that is periodically read by the on-line component to update the in-memory API ID, product key and API validity flag values. As such the on-line component is able to service a high volume of API requests for data with a low latency.
