RSS feeds
Every tracker has a private RSS feed at its feedUrl:
https://usefeeds.com/feeds/3f9c1a…e2.xmlThe token in the URL is the only credential, so treat the URL like a password. Anyone with it can read the feed. To replace it, delete the tracker and create it again.
The feed lists the latest 100 posts delivered to the tracker. Reading it is free and does not trigger a check: new posts appear when the tracker’s own checks find them. If a tracker’s account can no longer be read, its feed answers 410 Gone.
RSS works with feed readers and with automation tools that watch feeds, such as Zapier, n8n, Make, IFTTT, or Slack’s RSS app.
