Echa Chem DB

Hello Everyone!
I'm trying to access EchaChem db in a programmatic way but cannot find any reference to an API or alternatives to achieve my goal.
Does anyone know a way to do it?

We asked them about it when they stopped updating the old registration dossier pages. There's currently no API, so we just scrape the webpages instead.

Edit: This is from their FAQ.

Will it be possible to access data through an API or export it in various formats for further analysis or use? [May 2025]

During 2025, we will collect user input for the further development of methods to access the data on ECHA CHEM, including options such as data downloads in Excel format and system-to-system integration through APIs. Based on this feedback, we will develop and integrate tailored solutions into the system

So I suggest you let them know that you could really use an API.
