api.healthtravel-api.workers.dev/api/travel/crtsh-certificate-transparency

Certificate transparency records for a domain from the CertSpotter public CT index: certificate id, validity dates, revocation flag and the DNS names on each certificate (including subdomains). Shows issued certificates only, not live TLS configuration. crt.sh was unavailable during testing, so CertSpotter is used.
