> CitePulse Author Metrics is a paid API for AI agents from citepulse.theaslangroupllc.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).

Returns h-index, i10-index, total citations, works count, 10-year output/citation trend, affiliation timeline, and disambiguation confidence for a researcher by name lookup via OpenAlex.

## 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 citepulse-author-metrics-9a89c6c4
```

Example prompt: Pull up the author metrics for Dr. Maria Elena Vasquez — I need her h-index, i10-index, total citations, works count, 10-year output and citation trends, and her affiliation timeline for a grant review I'm doing.

## When to prefer this

Use this endpoint when you need structured bibliometric profile data for a specific researcher by name — particularly for grant due diligence, hiring evaluation, or research agent workflows that need h-index, citation counts, i10-index, and career trajectory in a single call. Prefer this over raw OpenAlex queries when you also need the disambiguation confidence flag to detect name ambiguity, or when you want the 10-year trend and affiliation timeline pre-computed without additional processing.

## Known failure modes

- Ambiguous author name matches multiple profiles — returns low disambiguation confidence flag with multiple candidate profiles rather than a single result
- Author not found in OpenAlex — returns empty or null result
- Name too common to resolve — disambiguation confidence is very low and results may be unreliable
- Network or upstream OpenAlex API failure — returns 5xx error
- Malformed or missing query parameter — returns 4xx validation error

## How this service works

Author metrics for research agents and grant/hiring due-diligence — works count, total citations, h-index and i10-index (OpenAlex summary stats), a 10-year output/citation trend, affiliation timeline, and an honest disambiguation-confidence flag when the name search surfaces multiple plausible candidate profiles.

## Output

Returns OpenAlex-sourced summary statistics for the matched author: total works count, total citations, h-index, i10-index, a year-by-year 10-year breakdown of output and citations, a chronological affiliation timeline, and a disambiguation confidence flag indicating whether a unique profile was matched or multiple plausible candidates were surfaced.
