# Research Publication Trend by Year for a Topic

**Use case:** 

The number of scholarly works per publication year on a topic (here: CRISPR in the title, since 2012) from OpenAlex, with each year's share of the total. For analysts, investors and research managers sizing a field and spotting growth. Change the query, or set groupBy to authorships.institutions.country_code to see which countries publish most.

## Input

```json
{
  "entity": "works",
  "query": "CRISPR",

## About this Actor

This example demonstrates how to use [OpenAlex Scraper — Academic Papers, Citations, Authors](https://apify.com/yadroo/openalex-works.md) with a specific input configuration.

## 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/yadroo/openalex-works.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`).
