# Hugging Face Paper Full Text API

The whole paper as Markdown, ready to index or quote, with its size and source page.

`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.

## FAQ

### Does this return the abstract or the whole paper?

The whole text, as Markdown. The abstract is paper.summary on the paper endpoint.

### 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?

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.
