Searchanise requests blocked in DuckDuckGo browser

[incrize]

Hello,

We’re experiencing an issue with our search application (Searchanise) when used in the DuckDuckGo browser.

It appears that requests from our JavaScript scripts to the domain searchserverapi1.com are being blocked by the browser. As a result, search functionality does not work correctly for users browsing with DuckDuckGo.

• Could you clarify why this domain might be blocked by DuckDuckGo?
• Is there a recommended way to make such API requests compliant with DuckDuckGo’s privacy protections?
• Are there specific requirements that we should follow?

We’d appreciate any guidance on how to resolve this issue.

Best regards,
Searchanise team

Hey @incrize
It does look like this is a false positive. Do you have an example site where blocking this domain is causing problems that I could look at?

Thanks, @jdorweiler, for your response.

Here is our demo Shopify store: https://searchanise-demo.myshopify.com/

If you type a search query into the input field—for example, t-shirt—you’ll see the following message in the browser console:

Content blocker prevented frame displaying https://searchanise-demo.myshopify.com/ from loading a resource from https://searchserverapi1.com/getwidgets?api_key=.....

The same request works successfully when sent to the searchserverapi.com domain.

In the file /Applications/DuckDuckGo.app/Contents/Resources/trackerData.json, we found the following entry:

"searchserverapi1.com": {
    "domain": "searchserverapi1.com",
    "owner": {
        "name": "searchserverapi1.com",
        "displayName": "searchserverapi1.com"
    },
    "prevalence": 0.00299,
    "fingerprinting": 1,
    "cookies": 0,
    "categories": [],
    "default": "block"
},

It appears that this domain was added in the following PR: duckduckgo/tracker-blocklists#64
