DESIGN A CONTRACT YOU CAN INSPECT.

API design is the shared thread across ArmAPI.com. Whether an action changes a local drawing, proposes a robot task, or begins a virtual round, its interface needs to explain what inputs mean and what a return value establishes.

This reading path crosses subject boundaries deliberately. Start with the robot arm beginner’s guide for a basic command vocabulary. Then compare remote task lifetimes, agent tool permissions, and game result identities. Watch for the same distinction in each context: acceptance is not necessarily execution, and presentation is not necessarily verification.

Use the local API reference as a compact concrete example. It documents supported poses, strict parameter types, state snapshots, revisions, and errors without implying physical control. After reading, try writing the contract for one operation in your own project: required context, permitted caller, duplicate behavior, result state, and recovery path. The useful outcome is a clearer boundary, not a larger collection of endpoints.
