# The Legacy Search API is deprecated

Censys Search API deprecated /api/* without giving a shutdown date yet.

Censys has deprecated the Legacy Search API without a specific shutdown date, as part of a plan to decommission it in 2026. This change impacts calls to all /api/* endpoints on search.censys.io, which will eventually fail. The host data backend will be updated on March 31, 2026.

## What to use instead

Transition to the Censys Platform API, using global data under /v3/global/ with a Platform personal access token. Moving requires more than swapping an identifier: you must create a Censys Platform account, obtain a new token, and rewrite your queries to use CenQL instead of the Legacy Search syntax.

The Platform API needs a Censys Platform account, a new token and rewritten queries (CenQL instead of the Legacy Search syntax).
