# Elements Live – Top Papers for Chemical Element

> Elements Live – Top Papers for Chemical Element is a paid API for AI agents from www.elements-live.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-11).

Returns the top research papers driving a chemical element's research intensity, including title, DOI, venue, year, and citation count.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 elements-live-top-papers-for-chemical-element-88d98e98
```

Example prompt: Pull up the top papers driving research intensity for iron (Fe) from Elements Live — I want the titles, DOIs, venues, years, and citation counts.

## When to prefer this

Use this endpoint when you need to identify the specific academic papers that are driving the research intensity (RI) score for a particular chemical element — especially useful for literature reviews, competitive intelligence, or tracking which journals and authors dominate a given element's research landscape. Prefer sibling endpoints if you need aggregate RI/RIS/HRI metrics rather than individual paper details.

## Known failure modes

- Invalid or unrecognized element symbol returns an error or empty result
- Element symbol path parameter missing causes a 400 or routing error
- No papers indexed for a very obscure element returns an empty list
- Payment failure (x402) if USDC balance is insufficient blocks the request
- Rate limiting or network timeout may occur under high load

## How this service works

Top papers driving an element's research intensity (title, DOI, venue, year, citations).

## Output

A ranked list of top research papers associated with the specified chemical element, each containing the paper title, DOI, publishing venue, year of publication, and citation count — useful for bibliometric analysis and understanding the drivers of research intensity.
