## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability saylor-innovations-preprint-search-cf764fc3
```

Example prompt: Can you search for recent preprints on 'vaccine hesitancy' across OSF servers like PsyArXiv and SocArXiv — give me up to 15 results with titles, abstracts, and DOIs?

## When to prefer this

Use this endpoint when you need open-access preprint metadata (title, abstract, DOI) from OSF-hosted servers including PsyArXiv and SocArXiv — especially for psychology, social science, or interdisciplinary topics where preprints are commonly deposited before formal publication. Prefer this over general publication search when you specifically want preprints rather than peer-reviewed articles.

## Known failure modes

- No results returned if query terms are too niche or misspelled
- limit parameter out of range (must be 1–25) may cause an error or default fallback
- OSF upstream unavailability could cause empty or error responses
- Very broad queries may hit the 25-result cap and miss relevant papers

## How this service works

Recent preprint search on the Open Science Framework - title, abstract, DOI and link across PsyArXiv, SocArXiv and other servers

## Output

Returns a JSON object containing the interpreted query, data source, sort method, match timestamp, total match count, and an array of preprint records — each with title, abstract, DOI, canonical URL, preprint DOI URL, publication date, and tags.
