## 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 learning-analytics-publication-sample-breakdown-6cdb49ea -d '<json body>'
```

Example prompt: Pull a sample breakdown of up to 15 learning analytics publications from Crossref, including their DOI references and source labels — query should be 'learning analytics in higher education'.

## When to prefer this

Choose this endpoint when you need a quick, sourced sample of academic publications in the learning analytics domain with DOI-level traceability and Crossref attribution. It is well-suited for literature review bootstrapping, research scoping, or building citation lists — especially when you want labelled summaries rather than raw search results. Prefer alternatives if you need full-text retrieval, non-education domains, or real-time publication feeds.

## Known failure modes

- Query returns no results if the search term is too narrow or obscure
- max_results exceeds 30 — validation error
- Crossref metadata may be incomplete for some DOIs, resulting in partial attribution
- Rate limiting or payment failure on the x402 protocol layer
