SpamRATS! Subscription Fees

SpamRATS! RBL queries are free to query with a registered API key for volumes less than 40,000 daily queries. For volumes exceeding this limit, commercial subscription pricing starts at $500 USD per year, dependent on the scale of volume. For full details of what qualifies for free use, please refer to our Terms of Service.

However, if you are a spam protection or security company and you are making money from providing the protection offered by SpamRATS we ask that you enter into a data licensing agreement. Please contact us for the pricing details for your business model.
