# Hugging Face Paper API

One paper with its authors, abstract, project page, citing repositories and optional comments and upvoters.

`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.

## 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.
