About this endpoint

GET /v1/hugging-face/papers/{arxivId} returns paper with id, title, url, summary, publishedAt, upvotes, numComments, thumbnailUrl, githubRepo, githubStars, organization, submittedBy, submittedOnDailyAt, aiSummary and aiKeywords, plus authors, projectUrl, aiSummaryModel, mediaUrls, discussionId and linked.

linked holds the first page of citing models, datasets and spaces with totalModels, totalDatasets and totalSpaces. Add include=comments,upvoters to fill comments and upvoters; both are null without it. A version suffix is accepted and ignored.

Hugging Face Paper API FAQ

How do I get the comments and upvoters?

Pass include=comments,upvoters. Without it, both fields are null.

Can I pass a versioned id such as 2305.10601v2?

Yes. The version is dropped because the platform keeps one page per paper.

Where are all the citing repositories?

linked shows only the first page. The repositories endpoint lists up to 100 of each kind, with cappedLists telling you when more exist.

How much does a paper lookup cost?

Pricing is documented on the operation in the API registry (shown on this page). Confirm on every response with meta.creditsCharged: that field is the billing source of truth.
