About this endpoint

GET /v1/hugging-face/papers/{arxivId}/content returns content with markdown, sizeBytes and sourceUrl. The markdown is the paper's full text, not the abstract.

lookupStatus: found with content: null means the paper exists but the platform has no text for it. not_found means the paper itself is not on the platform. A version suffix in the id is accepted and ignored.

Hugging Face Paper Full Text API FAQ

Does this return the abstract or the whole paper?

Why is content null when lookupStatus is found?

The paper exists but the platform has no full text for it. Not every paper has one.

What is sourceUrl?

The paper page the text belongs to, so you can link back to it.

How much does a full text lookup cost?
