Api Endpoint

Readr SubEnum

Subdomain enumeration via Certificate Transparency logs (crt.sh, with Cert Spotter fallback): unique subdomains with issue/expire date ranges, grouping by function (www, mail, api, dev, admin, cloud, cdn...), issuing CAs and cert counts. Recon-grade attack-surface mapping for a domain. Query params: domain (required), limit (optional, default 100, max 250).
