## 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 manylives-me-scholarly-paper-search-631054e8
```

Example prompt: Search for scholarly papers on 'retrieval augmented generation' published since 2021 — give me the top 5 results with titles, authors, citation counts, and any open-access links.

## When to prefer this

Choose this endpoint when you need to search academic literature with bibliographic metadata including citation counts and open-access links in a single call. Prefer it over general web search when you need structured scholarly data (DOI, venue, authors) rather than raw HTML, and when relevance ranking across the academic corpus matters. It is especially useful for literature reviews, citation gathering, and discovering recent peer-reviewed work in a field.

## Known failure modes

- Missing required query parameter 'q' returns an error
- Query returns zero results if the topic is too niche or misspelled
- 'since' parameter with an invalid year format may return an error or be ignored
- 'limit' exceeding 25 is capped or rejected
- Open-access URL field may be null if no free version exists
- Rate limiting or payment failure results in a 402 or 429 error

## How this service works

Search scholarly papers: title, year, first authors, venue, citation count, DOI and a free full-text link when one exists, most relevant first.

## Output

Returns a JSON array of papers sorted by relevance, each with DOI link, publication year, title, venue name, list of authors, citation count, and an open-access full-text URL when available.
