## 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-data-desk-pubmed-icite-paper-impact-b0e5e27d
```

Example prompt: Can you pull the iCite citation metrics for PubMed IDs 28968713, 31806903, and 30442948 — I want to see their Relative Citation Ratio, NIH percentile, and whether any are flagged as clinical?

## When to prefer this

Use this endpoint when you need structured NIH iCite bibliometric data for specific PubMed-indexed papers identified by PMID. It is ideal for grant writing, systematic reviews, research evaluation, or any workflow requiring Relative Citation Ratio, NIH percentile, or clinical/translation flags for up to 20 papers at a time. Prefer this over general web searches or PubMed abstract lookups when quantitative citation impact data is required.

## Known failure modes

- Invalid or non-existent PMIDs return empty article entries or are omitted from results
- More than 20 PMIDs submitted may result in truncation or an error
- PMIDs for very recent papers may lack citation metrics if iCite has not yet indexed them
- Network or upstream NIH iCite unavailability results in a failed response
- Malformed pmids query parameter (e.g. non-numeric values) may return an error

## How this service works

Paper impact for PubMed IDs from NIH iCite - citations, Relative Citation Ratio, NIH percentile, expected rate, clinical flags and translation potential

## Output

A JSON object containing a count of returned articles and an array of article objects, each with fields including PMID, DOI, title, authors, journal, year, citation count, citations per year, field citation rate, expected citations per year, Relative Citation Ratio, NIH percentile, human/animal/molecular-cellular shares, clinical flag, cited-by-clinical-article flag, and potential-to-translate score. A source field identifies NIH iCite and a note field may provide caveats.
