• add_links_to_group — Add up to 25 links to a group in one call. Idempotent: links already in the group are reported in alreadyMembers rather than failing. Fails with not_found if any linkId is unknown (nothing is added).
• create_group — Create a group to organise short links (e.g. a campaign or a venue). Groups are many-to-many: a link can be in up to 20 groups. Add links with add_links_to_group, or pass groupIds when creating/updating a link.
• create_short_link — Create a short link that redirects to targetUrl, or shows a link page (pass page instead of targetUrl). Returns the link, including linkId (use it with the other tools) and shortUrl (share this). Give a slug for a memorable URL, otherwise a random 8-character one is generated. Slugs are unique across all tenants and cannot be changed later (409 if taken; route names like "api", "admin", "health" are reserved).
• delete_group — Delete a group. Its links are NOT deleted; they just stop being members.
• delete_short_link — Permanently delete a short link and remove it from its groups. Its short URL and any printed QR codes stop working (404) and the slug becomes free for anyone. Prefer update_short_link status "paused" if the link may come back.
• get_custom_domain — Get this tenant's custom (alias) domain and advance its setup as far as DNS allows. Use it to check progress after creating a DNS record. Lifecycle: pending_validation (create the certificate_validation record, and the optional ownership_verification TXT if listed) → provisioning (automatic, seconds) → pending_dns (create the routing CNAME from the domain to `target`) → active. Nothing advances on its own: call get_custom_domain after each DNS change to move it along. The response always carries `dnsRecords` (exact name/type/value to create, with `done` once seen) and `instructions` saying what to do next.
• get_group — Fetch one group. To see its links use list_short_links with group = groupId.
• get_group_visits — Combined visit analytics for a group's current member links: totals {visits, qr, direct, bot} and a zero-filled per-day breakdown (UTC). Links removed from the group no longer count.
• get_short_link — Fetch one short link by linkId, including its groupIds and lifetime visitCount.
• get_short_link_visits — Visit analytics for one link: totals over the window ({visits, qr, direct, bot}; visits = qr + direct, bots such as link-preview crawlers are counted separately and excluded from visits), a zero-filled per-day breakdown (UTC, oldest first), and the most recent individual visits (newest first, with source, referrerHost, userAgent, country when known, and ruleId when a redirect rule decided it; kept 90 days). byRule splits the window's visits by rule (fallback = went to the link's targetUrl); daily entries carry byRule on days a rule matched. For link pages, byItem counts button clicks per item (daily entries carry clicks by item id).
• list_groups — List your groups (with linkCount), ordered by groupId. Page with cursor = nextCursor.
• list_short_links — List your short links, newest first. Filter by tag and/or groupId. A page can hold fewer than limit items even when more exist: keep calling with cursor = nextCursor until nextCursor is absent.
• preview_link_page — Render a link's page as HTML for a simulated visit, without recording anything: the saved page, or a draft (page) to try before saving (pictures given as data URLs are drawn inline; nothing is stored or charged). Returns the visible item ids (items with "when" conditions depend on the visit) and the HTML.
• remove_custom_domain — Remove this tenant's custom domain. Short links immediately stop resolving on it (QR codes printed with it break) and new short URLs use the platform domain. The DNS records can be deleted afterwards.
• remove_link_from_group — Take one link out of a group. The link itself is untouched.
• render_qr_code — Render a QR code as a PNG image. Pass linkId to render a short link: the image encodes {shortUrl}?s=qr so scans are counted as qr visits, and the link's qrStyle is the default look. Or pass data to render any text (URL, Wi-Fi config, vCard...) as a static QR code that is not tracked. Returns the image plus a text line naming exactly what was encoded. Styles are free: module shapes, corner markers, a logo or a halftone photo. For SVG, use GET /v1/links/{linkId}/qr?format=svg.
• set_custom_domain — Serve all of this tenant's short links on a domain it controls, e.g. "go.acme.com" → https://go.acme.com/{slug}. Once active, new short URLs and QR codes use it; links keep working on the platform domain too. One domain per tenant: setting a different one replaces (and tears down) the current one. Setting the same one again is harmless, and restarts it if it failed. Two DNS records are needed at the domain's DNS provider, returned one at a time: first a record (TXT or CNAME) that proves control (for the TLS certificate), then a CNAME pointing the domain at the platform. Lifecycle: pending_validation (create the certificate_validation record, and the optional ownership_verification TXT if listed) → provisioning (automatic, seconds) → pending_dns (create the routing CNAME from the domain to `target`) → active. Nothing advances on its own: call get_custom_domain after each DNS change to move it along. The response always carries `dnsRecords` (exact name/type/value to create, with `done` o
• set_domain_home_page — Choose the link that the root (/) of this tenant's custom domain shows: a link page becomes the domain's home page, a redirect link sends / there. Pass linkId null to clear it (/ answers 404 again). Has no effect on the platform domain.
• test_redirect_rules — Dry run: which destination would a visit with these properties get from this link's rules? For a link page with no matching rule it returns page.itemIds (the buttons that visit would see) instead of targetUrl. Records no visit. Pass a real userAgent to test device routing, e.g. iPhone: "Mozilla/5.0 (iPhone; CPU iPhone OS 17_0 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/17.0 Mobile/15E148 Safari/604.1", Android: "Mozilla/5.0 (Linux; Android 14; Pixel 8) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/126.0 Mobile Safari/537.36". Returns targetUrl, matchedRule (absent when the link's targetUrl is used) and the context the rules saw (os, device, browser, language, country, referrer, source, query, at).
• update_group — Rename a group or change its description or color. Membership doesn't change here.
• update_short_link — Change a short link. Only the fields you pass change; tags, metadata, qrStyle and groupIds are replaced wholesale (pass the full new list; [] clears). Set targetUrl to send visitors somewhere else: the short URL and printed QR codes keep working. Set status "paused" to make the short URL answer 410, "active" to resume. The slug cannot be changed. page replaces the whole link page (a redirect becomes a page); page: null with a targetUrl turns a page back into a redirect.
