New feature has been deployed on the Fediseer where it can autogenerate special .svg badges for your Fediverse domain which you can embed directly.
The images have an embedded link to the endpoints proving this, but that doesn't work in markdown, so when embedding in markdown, you need to put the link manually.
Guarantees
https://fediseer.com/api/v1/badges/guarantees/{domain}.svg
This badge will display which other fediverse domain guaranteed that your domain is not spam. Remember each instance can only have 1 guarantor due to the chain of trust.
Example: 
[](https://fediseer.com/api/v1/whitelist/lemmy.dbzer0.com)`
Endorsements
https://fediseer.com/api/v1/badges/endorsements/{domain}.svg
This badge will provide a count of how many other fediverse domains endorsed for yours. An instance can guarantee another instance for any reason.
Example: 
[](https://fediseer.com/api/v1/endorsements/lemmy.dbzer0.com)`
Display
You can place these anywhere you want on your site, but obvious suggestion is on the main sidebar. This will work for any domain known by the Fediseer. If your domain is not known, simply claim it and then find someone to guarantee for you.
