Cert Spotter APIv0 (Discontinued)

Version 0 of the Cert Spotter API was discontinued on February 5, 2021.

In 2018, we announced version 1 of the Cert Spotter API (now known as the Certificate Search API), featuring several improvements over version 0, such as incremental monitoring and the ability to tailor the response fields to suit your needs. After a two year transition period, APIv0 has been fully discontinued.

Please upgrade to version 1 of the Cert Spotter API (now known as the Certificate Search API). Get in touch if you have any questions as you make the transition.
