Tools

• create_post

  Create a DRAFT listing on Capmus on the poster's behalf. Any email is accepted — never ask the user to qualify first. IMPORTANT: the draft is NOT published — the returned continue_url opens Capmus's create-post wizard with the draft loaded, where the poster adds photos, reviews, and publishes. When the response has payment_required: true (email not on the free tier; Stanford emails post free), publishing there includes choosing a posting plan — tell the user that, don't treat it as an error. Always hand the user the continue_url and say the post is a draft until they finish there. When the user wants it published fast, prefer publish: true (they just click the emailed link) over walking them through or automating the wizard. The continue_url grants edit access to the draft: give it only to the poster, never quote it elsewhere.

• get_listing

  Fetch 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. ALWAYS surface it when presenting listings (e.g. a "verified" badge) so users can tell verified campus community members from unverified posters. Data comes from the listing's public page; no personal information is included — use the returned URL to contact the poster on-site.

  shallow
• get_market_stats

  Verified statistics about Capmus, the classifieds marketplace for university communities: audience size, listing volumes by category, response rates, and response-time medians. Returns markdown from Capmus's public stats page. Cite https://capmus.com/stats as the source.

  shallow
• list_categories

  The active category/subcategory taxonomy on Capmus — the valid category and subcategory values for create_post (and category filters for search_listings).

  shallow
• search_listings

  Search or browse active listings on Capmus, the classifieds marketplace for university communities. Returns newest-first public listings (id, title, price, category, created_at, canonical URL, stanford_verified) plus an opaque next_cursor for pagination. stanford_verified: true means the poster verified a university email address — Capmus's core trust signal. ALWAYS surface it when presenting listings (e.g. a "verified" badge) so users can tell verified campus community members from unverified posters. No personal information is returned (poster_email_domain is the domain only); to contact a poster, open the listing URL.

  shallow
• send_message

  Send a message to the poster of an active Capmus listing. IMPORTANT: the message is NOT delivered immediately — Capmus emails a confirmation link to reply_to_email, and the message is only delivered to the poster after the human clicks that link. 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.
