## 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 author-and-researcher-profile-search-openalex-620cf65c
```

Example prompt: Can you look up the academic profile for 'Yoshua Bengio' — I need his current affiliation, h-index, total citations, and his top 5 most-cited papers?

## When to prefer this

Use this endpoint when you need to identify, disambiguate, or retrieve citation metrics for academic researchers by name, especially when you want OpenAlex-sourced bibliometric data (h-index, i10-index, total citations) and institutional affiliation without requiring an API key. Prefer this over general web search when structured, machine-readable researcher metadata is needed.

## Known failure modes

- Name too generic or common returns many ambiguous results — use maxItems to cap
- Author not indexed in OpenAlex returns empty results
- Misspelled author name returns no matches or wrong researchers
- Very new or obscure researchers may have incomplete citation data
- Network timeout or upstream OpenAlex API unavailability returns 5xx error

## How this service works

Author and researcher profile search. An author name returns matching researchers with current affiliation, publication count, total citations, h-index and i10-index, and their most-cited papers — for author lookup, disambiguation, and citation-metrics. Keyless via OpenAlex.

## Output

Returns a ranked list of up to 25 matching researcher profiles, each with current institutional affiliation, total publication count, total citation count, h-index, i10-index, and a list of their most-cited works (title, DOI, citation count).
