The ESCAPE Project\footnote{\url{https://www.projectescape.eu}} brings together the astronomy, astroparticle, and particle physics communities to address fundamental challenges in data-driven research, driven by the goals and needs of major European research infrastructures, or ESFRIs.

%\ssindex{projects!EOSC}
ESCAPE aims to produce versatile solutions to support the implementation of the European Open Science Cloud by fostering a multi-disciplinary environment, including open data management according to FAIR principles.
Our goal is to enable interoperability between facilities, encourage cross-fertilization, and develop joint multiwavelength and multimessenger data processing and analysis capabilities.
We are addressing this by developing a range of services, including data infrastructure, a software repository, virtual observatory integration, and a citizen science programme.
%\ssindex{science portal}
ESAP, the ESFRI Science Analysis Platform, is under development by ESCAPE's Work Package 5, to facilitate access to the full range of ESCAPE services.
ESAP aims to provide a comfortable and consistent gateway to the full range of project-provided functionality, while being customizable and adaptable to the needs of particular science goals or research infrastructures.

ESAP is a web application, implemented in Python, Django, and React.\footnote{\url{https://www.python.org}; \url{https://www.djangoproject.com}; \url{https://reactjs.org}}
It is designed around the \emph{API Gateway}, which brokers requests across a range of independent services, and a web-based \emph{user interface}.
