An API monitoring tool initiates API calls against your chosen endpoints and then records the response received.

API monitoring tests can be simple such as simple health and uptime checks or can be very elaborate running through a long sequence of API calls and checking against specific status codes, body fields, and more.

Unlike blackbox testing and monitoring, API observability is a form of whitebox monitoring that requires an agent or SDK to passively log API traffic to an observability service.

The goal of API observability is to proactively discover these unknown unknowns and remedy them whether it’s something wrong with your own code or the API consumer’s code.

However, a key theme for observability is the ability to answer any question around your API and services without planning ahead for which metrics need to be monitored.
