- Wait for a response body to match a `regex` pattern:

`wait4x http {{https://api.example.com/status}} --expect-body-regex '{{\"status\":\s*\"healthy\"}}'`

- Wait for a specific JSON field to exist using GJSON path syntax:

`wait4x http {{https://api.example.com/status}} --expect-body-json "{{services.database.status}}"`

- Wait for a response with custom request headers:

`wait4x http {{https://api.example.com}} --request-header "{{Authorization: Bearer token123}}"`

- Wait for a specific response header to match a value:

`wait4x http {{https://api.example.com}} --expect-header "{{Content-Type=application/json}}"`

- Wait using a TLS client certificate:

`wait4x http {{https://example.com}} --cert-file {{path/to/cert.pem}} --key-file {{path/to/key.pem}}`
