# Research Paper Checks – Author Profile by Name

> Research Paper Checks – Author Profile by Name is a paid API for AI agents from research-papers.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-31).

Returns the best-matching researcher's profile by name, including works count, citation count, h-index, i10-index, institution, top topics, and an ambiguity warning if multiple authors could match.

## 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 research-paper-checks-author-profile-by-name-131d87ca
```

Example prompt: Can you look up Geoffrey Hinton's researcher profile — I want to see his h-index, total citations, number of works, and which institution he's affiliated with?

## When to prefer this

Use this endpoint when you need a quick academic profile lookup by researcher name and can tolerate best-match disambiguation rather than exact ID lookup. Ideal when you have a name but no ORCID or OpenAlex ID. Prefer this over paper-level or journal-level endpoints when the subject of interest is the researcher themselves. The ambiguity warning and alternatives list make it useful for identity verification workflows where name collision is a concern.

## Known failure modes

- No matching author found for the given name — returns null match with empty alternatives
- Name is highly ambiguous (common surname) — returns best guess with ambiguity warning and list of alternatives
- Author exists but has incomplete data in OpenAlex — some fields (e.g. ORCID, institution) may be null
- Upstream OpenAlex API unavailable — degraded flag set to true with partial or no data
- Malformed or missing name parameter — request rejected with validation error

## How this service works

Researcher profile by name: works, citations, h-index and institution of the best match, with an ambiguity warning.

## Output

Returns a structured profile of the best-matching author including: full name, OpenAlex ID, ORCID (if available), number of works, total citations, h-index, i10-index, affiliated institution, top research topics, two-year mean citedness, a human-readable summary, a verdict on match confidence, a list of alternative matches if the name is ambiguous, a disclaimer, the source URL, and a timestamp.
