First Call

Most first calls should start from discovery, not direct execution.

1. Discover a host

uxc petstore3.swagger.io/api/v3 -h

2. Inspect one operation

uxc petstore3.swagger.io/api/v3 get:/pet/{petId} -h

3. Invoke it

uxc petstore3.swagger.io/api/v3 get:/pet/{petId} petId=1

Tips

• Use key/value arguments for simple calls.
• Use positional JSON for nested objects.
• Keep --text for human-readable output; JSON is the default contract.
