Definitions of key terms and concepts used in APX
A
Agent
An intelligent assistant that helps test and analyze APIs. Each API has one agent that can be started or stopped on demand. Agents execute mission profiles and provide real-time insights.
API
Application Programming Interface. In APX, an API represents a service you want to test, registered with a name, endpoint, and version.
Active Session
A currently running test session that you can interact with in real-time. Active sessions appear as tabs in the main stage area.
C
Context Panel
The middle column of the APX interface (384px wide). Shows either a list of all APIs or details for a selected API, including session management.
Command Center Layout
The 3-panel layout design used in APX: floating action bar (left), context panel (middle), and main stage (right).
E
Endpoint
The base URL of an API service. For example: https://api.example.com/v1
F
Floating Action Bar
The left sidebar in APX (14px collapsed, 56px expanded). Contains navigation, add API button, settings, and user profile.
M
Main Stage
The right content area of APX that displays session tabs, insights, settings, and other primary content.
Mission Profile
A predefined testing strategy that guides agent behavior. Examples include “Exploration” (general testing), “Security” (security testing), and “Performance” (load testing).
P
Past Session
A completed test session that can be viewed but not modified. Past sessions preserve all conversation history and results for future reference.
Project
The top-level organizational unit in APX. Projects contain APIs, sessions, and team collaboration settings.
S
Session
An interactive testing conversation with an API. Sessions can be active (running) or past (completed). Multiple sessions can run concurrently in separate tabs.
Session Tab
A tab in the main stage area that contains an active session. Similar to browser tabs, you can switch between multiple session tabs.
T
Tab-Based Interface
The multi-tab system in APX that allows you to work with multiple sessions simultaneously, similar to a web browser.
Tribal Knowledge
Undocumented information about system behavior that exists only in team members’ heads. APX helps convert tribal knowledge into documented, verifiable facts.
W
