TL;DR. Metadata Manager will be retired at the end of 2025. Over the past four years, we have been developing a new helper tool to replace it, and that tool has now reached a stage of maturity that means we will be able to switch off Metadata Manager by the end of the year.
Our REST API makes all of the metadata we hold publicly available. It receives the majority of our API traffic, with around 1 billion hits per month. It’s one of the key ways that we fulfil our mission to make research objects easy to find, cite, link, assess, and reuse. From 1 December 2025, we will be revising the rate limits for the public and polite pools of the REST API to ensure that we can maintain a stable and reliable system, and that metadata is freely available to everyone.

Select a title to retrieve a list of DOIs for the title, and flagged fields for each DOI. For example, the DOIs in this report lack page and author information:
Although the deposit section of the schema specifies that some bibliographic metadata is optional for content registration purposes, we strongly encourage members to register comprehensive metadata for each item registered.
