There are three ways in. They coexist: pick whichever fits how you work.
The Wego skill (for AI agents)
Open the setup page and paste the one line there into your agent. The skill installs the CLI (with your approval) and drives every funnel from natural language.
Wego CLI (for humans at a terminal)
One command per step, JSON on stdout so each step threads into the next. See Wego CLI.
Direct HTTP
Call the API yourself. The API Reference is written to double as an agent tool contract: every operationId is a stable tool name, and every error is machine branchable.
Whichever path you take, you first need a token: see Authentication.
