Is Open Access Helper Web safe?
Open Access Helper Web reads article DOI values from pages and sends them to open-access lookup APIs.
On page load, the extension extracts article DOI values from page metadata and site-specific scraping logic, then checks for alternative access options. It queries Unpaywall with the DOI in the URL and sends the DOI to CORE in a lookup request; if EBSCO access is configured, it also queries EBSCO entitlement APIs for that DOI.

What this publisher told the store about itself, and the other listings that told it the same thing.
Shared hosts - 3 hostnames
Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
