 [INSPIRE](https://inspirehep.net) is a trusted community hub that helps researchers to share and find accurate scholarly information in high energy physics.
 In addition to a regular web interface for interactive access to its content, a REST API is provided for programmatic access.
 The present document explains how to use this REST API.
 
+If you use the API in a scholarly work, please cite it using the following metadata:
+```bibtex
+@article{Moskovic:2021zjs,
+    author = "Moskovic, Micha",
+    title = "{The INSPIRE REST API}",
+    url = "https://github.com/inspirehep/rest-api-doc",
+    doi = "10.5281/zenodo.5788550",
+    month = "12",
+    year = "2021"
+}
+```
