About zip1.io

zip1.io is a URL shortener that gives away, for free and without an account, the features that most shorteners reserve for paid plans. Custom slugs are the headline — branded short links like zip1.io/spring-launch, described by the operator as the most-used feature on the platform — alongside per-link click analytics, click caps that expire a link after a set number of uses, password protection and scheduled expiry. There is no monthly link cap and no paywall. The API is the part that makes it relevant to agent workflows: link creation is a single POST with no API key and no signup, so a script or an agent can shorten a URL without any credential provisioning step at all, with snippets published for cURL, JavaScript and Python. It also ships MCP support, listed on the site as Claude-ready, so an agent can create and track links as a tool call rather than through a browser. The click-cap feature deserves a note because it is genuinely uncommon: locking a link to the first hundred, first thousand or a single click makes it usable for one-time invitations and limited offers without building that logic yourself. Stats are viewable per link.
