What is search_certificates?

Searches certificate transparency records by identity using the https://crt.sh JSON API. Returns every non-empty field exposed for each matching certificate and supports % wildcard queries. It runs on Notte's browser infrastructure and returns structured JSON, so you can call it like any other API — pass identity and get the result back without maintaining a scraper.
