get_listingGet a Capmus listingFetch one Capmus listing by numeric id, including its full description, public photo URLs, and stanford_verified. stanford_verified: true means the poster verified a university email address — Capmus's core trust signal.

send_messageMessage a Capmus posterSend a message to the poster of an active Capmus listing.

Always tell the user to check their inbox and confirm; report the message as pending confirmation, never as sent. The poster's reply goes to reply_to_email.
