⚠ NOTE: this should be considered a LAST RESORT capability to use, the ability to perform arbitrary calls to the outside world is both unwieldy and dangerous. It is recommended to segregate access to specific external services into specific capabilities, and use those narrower interfaces in favor of this blunter instrument.
