## 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 sitecheck-web-intel-datacite-doi-metadata-search-c7b024d6
```

Example prompt: Search DataCite for up to 10 research datasets related to 'SARS-CoV-2 genomic sequences' and give me the DOI, title, publisher, and landing page for each result.

## When to prefer this

Choose this endpoint when you need structured bibliographic metadata (DOI, creators, publisher, year, resource type) for research datasets, software, or other scholarly outputs indexed by DataCite. Prefer it over general web search when you specifically need citable DOIs and landing pages for academic outputs. Not suitable for full-text retrieval, citation counts, or journal articles not indexed by DataCite.

## Known failure modes

- Empty results if the query matches no DataCite records
- Limit parameter out of range (must be 1–25) may cause error or default behavior
- Query string too long (over 200 characters) will be rejected
- DataCite API downtime causes upstream failure
- Ambiguous or very short queries may return irrelevant results

## How this service works

DataCite DOI search (public REST API, no key): DOI, title, publication year, resource type, publisher, creators and landing page for datasets, software and other research outputs. Metadata only.

## Output

Returns a list of matching research outputs from DataCite, each containing DOI, title, publication year, resource type (dataset, software, etc.), publisher name, creator names, and a landing page URL. Metadata only — no full-text content.
