DOI Foundation Information Scraper
Spider read doi.org in 162 ms without a browser and returned 34 lines of clean markdown, including sections like "WHO IS THE DOI FOUNDATION COMMUNITY?", "WHAT IS THE DIGITAL OBJECT IDENTIFIER (DOI)?" and "DOI Proxy Milestone".
The DOI Foundation is a not-for-profit organization. We govern the Digital Object Identifier (DOI) system on behalf of the agencies who manage DOI registries and provide services to their respective communities. We are the registration authority for the ISO standard (ISO 26324) for the DOI system and we are governed by our Registration Agencies.## WHO IS THE DOI FOUNDATION COMMUNITY?We are an international community of communities bound by a common interest in persistent infrastructure. So far, we have welcomed agencies that manage communities spanning entertainment, standards, the built environment, natural history collections, scholarly communications, and research data.## WHAT IS THE DIGITAL OBJECT IDENTIFIER (DOI)?A DOI name is a digital identifier of an object, any object — physical, digital, or abstract. DOIs solve a common problem: keeping track of things. Things can be matter, material, content, or activities.Designed to be used by humans as well as machines, DOIs identify objects persistently. They allow things to be uniquely identified and accessed reliably. You know what you have, where it is, and others can track it too.## DOI Proxy MilestoneIn December 2025, we passed the 3 Billion proxy resolution mark with a total of 3,071,362,438 resolutions for the month. Proxy resolutions have steadily increased over the years but nevertheless this is a significant milestone. To put it into perspective, it means that DOIs are resolved more than 1146 times a second or say it another way a DOI is resolved at the doi.org proxy once every 0.37 microseconds.We know that a lot of this usage comes from machines rather than humans but we can’t be sure how much. 19% of this usage comes from machines that have identified themselves as such but we’re pretty sure this is a low estimate of the amount of machine use.The same call, in code.
