bioRxiv content metadata filtered by funder ROR ID

The format of the endpoint is https://api.biorxiv.org/funder/[server]/[interval]/[funder ROR ID]/[cursor]/[format]

where 'funder ROR ID' must be provided. The API accepts the 9 character unique string that concludes the ROR ID as described here: https://ror.readme.io/docs/identifier. For instance, for the the full identifier, https://ror.org/02mhbdp94, the string that this API endpoint accepts is '02mhbdp94', which is the portion of the identifier following the final forward slash. A specific funder identifier can be found using the ROR search page, https://ror.org/search, or other resources on the ROR site.

'Interval' can be: 1) two YYYY-MM-DD dates separted by '/' with the first no earlier than 2025-04-10 (the inception date for funder metadata in the submission system); and 'cursor' is the start point which defaults to 0 if not supplied, or 2) a numeric value for the N most recent posts, or 3) a numeric with the letter 'd' for the most recent N days of posts.

Where metadata for multiple papers is returned, results are paginated with 100 papers served in a call. The 'cursor' value can be used to iterate through the result.

For instance, https://api.biorxiv.org/funder/biorxiv/2025-04-10/2025-07-10/00k4n6c32/45 will output 100 results (if that many remain) within the date range of 2025-04-10 to 2025-07-10 beginning from result 45 for bioRxiv papers with funding declaration of European Commission.

These date range endpoints will also accept a querystring paramater for subject category. The subject category can either be URL-encoded or can have underscore substituted for spaces in the category name. For instance, https://api.biorxiv.org/details/biorxiv/2025-04-10/2025-07-10/00k4n6c32/?category=cell_biology will output metadata for bioRxiv Cell Biology papers with funding declaration of European Commission for the specified interval.

The 'messages' array in the output provides information about what is being displayed, including cursor value, count of all items and count of new papers for the requested interval.

Available formats are JSON (json), and XML (OAI-PMH XML).

The following metadata elements are returned:
