## 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-publication-search-a2261c1d
```

Example prompt: Search for academic publications on CRISPR gene editing and give me the titles, authors, DOIs, and publication years for up to five results.

## When to prefer this

Use this endpoint when an agent needs quick publication metadata — DOIs, author lists, years, citation counts — for a keyword search without requiring full text or abstracts. Prefer it over general web search when structured bibliographic data with DOIs is the goal. Best suited for tasks like building citation lists, verifying authorship, or gauging how much literature exists on a topic.

## Known failure modes

- Query string shorter than 2 or longer than 160 characters returns a validation error
- No matching publications found returns an empty results array with totalResults of 0
- Upstream scholarly data source unavailable returns a service error
- Malformed or missing 'q' parameter returns a 400-level error

## How this service works

Find up to five publications with DOI identifiers, authors, publication years and citation counts. Returns metadata, not abstracts or full text.

## Output

A JSON object containing the search query echo, total result count, and an array of up to five publication records — each with title, DOI, URL, authors array, and publication year. Also includes a source attribution block with name and URL, and a retrievedAt timestamp.
