We have a new API it is available at this endpoint:
Everyone on the new system www3.blacklistalliance.com must use the new API.
The old API was https://api.blacklistalliance.com or https://api.theblacklist.click. If you attempt to use the old API with the new credentials it will reply with:
{ "status": "failed", "message": "Access denied for your API key and IP XXXX }. If you see this message it means your using the wrong API address.
All API parameters are the same between the old and new system so you should just have to change the api.blacklistalliance.net and the api key parts.
You can view API documentation for the new API here:
