# Japanese Research Author and Journal Leaderboard by Topic

**Use case:** 

Japanese research author and journal leaderboard for any topic, built from J-STAGE papers. One run lists the matching articles and ranks which researchers publish most and which journals carry the field, with citation totals when enrichment is on. Useful for R&D scouting, academic partnership search, and literature scoping. Change the keyword to map another field.

## Input

```json
{
  "query": "battery",
  "maxResults": 25,

## About this Actor

This example demonstrates how to use [J-STAGE Scraper: 学術論文・引用検索 Papers & Citation Leaderboard](https://apify.com/getascraper/jstage-scraper.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/getascraper/jstage-scraper.md) to learn more, explore other use cases, and run it yourself.


## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/getascraper/jstage-scraper.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
