# Services

CyCAT provides a public catalogue using an open API. [The Cybersecurity Resource Catalogue public API](https://api.cycat.org/) currently allows to query UUID, publishers and projects. Additional query possibilities and a web based interface will be added at a later stage.

CyCAT - The Cybersecurity Resource Catalogue public API services document is available as [OpenAPI 2.0 swagger file](https://api.cycat.org/swagger.json). [The documentation of the API is available in PDF](https://www.cycat.org/assets/docs/api-documentation-3.pdf).

The API currently already includes multiple sources such as MITRE ATT&CK, Sigma rules, MISP feeds, MISP galaxies. Don't hesitate to [contact](/contact) us if you would like to add a new catalogue.
