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.
