# Research Journals (/docs/core-concepts/indicators/research-journals)



Research-journal indicators are exposed via:

* `POST /indicators/research-articles/proofpoints`
* `POST /indicators/research-articles/time-series`

## Where The Data Comes From [#where-the-data-comes-from]

Trendtracker indexes research publications and links them into the same trend context used by topics and other indicators.

## Typical Questions [#typical-questions]

* Is this trend still primarily academic, or already commercial?
* Which topics are gaining scientific attention fastest?
* What publications support a trend narrative?

## Endpoint Pattern [#endpoint-pattern]

Like patents, research-journal endpoints use body filters for flexible querying:

* topic-driven,
* term-driven,
* date-constrained,
* or mixed.
