### Tool changes

- 2026-10-28 `get_watch_report` added
  - Get the state of every link in a printed-link watch: working, dead, moved, deactivated page, redirect changed or certificate expiring, what changed since the first check, the latest redirect chain and the last 30 days.
- 2026-10-28 `watch_printed_links` added
  - Watch up to 25 printed links (QR codes on menus, short links on flyers, posters, packaging, cards). Checks each one now and then once a day, and records the whole redirect chain. A link is flagged when it dies (fails twice, 6 hours apart), lands somewhere new, lands on a QR or short-link vendor's 'deactivated' page or a parked domain, changes how it redirects, or its certificate expires within 14 days. Returns the first results, page_url (a result page to hand to the person; shareable) and manage_url (private: edit, re-check, delete). No key needed.
- 2026-10-27 `auth` changed (description)
  - before: Sign in to b59.link to raise the rate limit from 2 to 300 requests/minute and own what you create. Pass api_key to get a session key straight away. Or pass email to have a 6-digit code emailed, then call again with email and otp to get a session key (new emails are signed up and also get their api_key). Send the session key as the HTTP header 'Authorization: Bearer <session_key>'.
  - after: Sign in to b59.link to own what you create (and for 300 requests/minute on the REST API). Pass api_key to get a session key straight away. Or pass email to have a 6-digit code emailed, then call again with email and otp to get a session key (new emails are signed up and also get their api_key). Send the session key as the HTTP header 'Authorization: Bearer <session_key>'.

## Tools (9)

- `auth`: Sign in to b59.link to own what you create (and for 300 requests/minute on the REST API). Pass api_key to get a session key straight away. Or pass email to have a 6-digit code emailed, then call again with email and otp to get a session key (new emails are signed up and also get their api_key). Send the session key as the HTTP header 'Authorization: Bearer <session_key>'.
- `create_tracker`: Create a free page-view tracker for a website. Returns the tag image URL and ready-to-paste snippets for the site's pages, plus the stats URL where views, visitors, pages and referrers are shown. When signed in, the tracker belongs to the account; otherwise keep the manage_token to claim it later.
- `generate_qr`: Generate a trackable QR code for a URL. Creates a b59.link short URL at the same time so scans are counted. Returns the short URL, a stats URL, and the QR code as a base64-encoded PNG.
- `get_stats_url`: Get the stats page URL for anything b59.link tracks: a slug or short URL, the destination URL of a short link or QR code, a tracker id or tag URL, or any page URL / domain that has a tracker tag. Stats themselves are viewed on b59.link; this returns where.
- `get_watch_report`: Get the state of every link in a printed-link watch: working, dead, moved, deactivated page, redirect changed or certificate expiring, what changed since the first check, the latest redirect chain and the last 30 days.
- `lookup_url`: Check whether a URL already has a b59.link short URL. Handles variations: http/https, www prefix, trailing slash. Returns the existing short URL and QR code if found.
- `make_qr_image`: Make a QR code image for any text (URL, Wi-Fi string, phone, email, plain text) without creating a short link. Supports colors, size and SVG. Returns the image plus a permanent image URL that can be embedded with <img src>. Use generate_qr instead when scans should be counted.
- `shorten_url`: Shorten a long URL and get a memorable b59.link short URL. Optionally specify a custom slug. Returns the short URL and a stats URL.
- `watch_printed_links`: Watch up to 25 printed links (QR codes on menus, short links on flyers, posters, packaging, cards). Checks each one now and then once a day, and records the whole redirect chain. A link is flagged when it dies (fails twice, 6 hours apart), lands somewhere new, lands on a QR or short-link vendor's 'deactivated' page or a parked domain, changes how it redirects, or its certificate expires within 14 days. Returns the first results, page_url (a result page to hand to the person; shareable) and manage_url (private: edit, re-check, delete). No key needed.
