Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 privacy-preserving-machine-learning-literature-search-a0910ae1 -d '<json body>'
```

Example prompt: Search the academic literature for papers on differential privacy in machine learning and give me up to 15 results with their DOI references and source attributions.

## When to prefer this

Use this endpoint when an agent needs structured academic citation data (DOIs, publisher metadata) specifically in the privacy preserving machine learning domain, sourced from Crossref. Prefer this over general web search when you need citable, publisher-verified references with DOIs rather than informal web results.

## Known failure modes

- Query returns zero results if search terms are too narrow or obscure
- max_results out of range (must be 1–30) returns validation error
- Crossref metadata may be incomplete or missing for some records
- Query string exceeding 200 characters is rejected
- Network or upstream Crossref API unavailability causes failure

## How this service works

privacy preserving machine learning: Literature search: Literature search on privacy preserving machine learning using Crossref publisher metadata. Returns DOI references and source attribution. Query can be overridden; sample summaries are labelled.

## Output

Returns a list of academic paper records including DOI identifiers, source attribution (publisher metadata from Crossref), and citation details relevant to the privacy preserving machine learning query. Sample summaries may be labelled.
