Before you connect

Questions about CrossRef.

The practical details behind the request, access and result.

Can I use CrossRef to find research papers?

Yes, you can ask your agent to search for papers by title, author, keywords, or even specific publication dates to find exactly what you need.

Does CrossRef need an API key?

No, this Connector handles all the connections for you, so you can start searching scholarly metadata immediately.

Can I look up multiple DOIs at once?

Yes, you can provide a list of DOIs to your agent, and it will pull the metadata for all of them in one step.

Can I find out who funded a specific research paper?

Yes, the Connector can identify the research funding organizations associated with various works in the database.

Does this capability provide the full text of articles?

No, it provides metadata like the title, abstract, and citation count, but not the full PDF or article text.

Can I find journal ISSNs?

Yes, you can search for journals by name to get their ISSNs, publisher details, and total work counts.

Do I need an API key?

No! CrossRef API is completely free and open. No authentication required. Just subscribe and start searching. Rate limit is 50 requests/second for polite pool.

What is a DOI?

DOI (Digital Object Identifier) is a unique alphanumeric string assigned to academic works. It provides a persistent link to the work's location online. Example: 10.1038/nature12373.

How can I filter search results?

Use the filter parameter with CrossRef filter syntax. Examples: 'type:journal-article' for journal articles only, 'from-pub-date:2024' for papers from 2024 onwards, 'has-abstract:true' for papers with abstracts, 'has-full-text:true' for open access papers.
