check_message_status | Delivery status of the confirmation email for a message submitted with send_message, by the status_key it returned. Use it when the user says they have not received the confirmation email. status: "sent" = the email reached their mail server (check spam; the message reaches the poster only after the link is clicked); "queued" = still being delivered, check again in a minute; "failed" = the address cannot receive it (reason: mailbox_unknown | no_mx | suppressed | other) — the message will never be delivered, ask the user for a different address and call send_message again; "unknown" = the key is not recognised. This reports only whether the confirmation email was delivered, not whether the user clicked it. |
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. |
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. |
list_categories | The active category/subcategory taxonomy on Capmus — the valid category and subcategory values for create_post (and category filters for search_listings). |
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. |
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. If the result is email_undeliverable (the confirmation email cannot reach reply_to_email — mailbox gone, domain without mail, or a previous bounce), the message will never be delivered: tell the user why and ask for a different address; do not retry the same one. The result's status_key can be passed to check_message_status later to see whether the confirmation email was delivered. |
