How this service works
Certificate-transparency history for a domain (crt.sh) — every TLS certificate issued, which doubles as subdomain discovery
Output
A JSON object containing the queried domain, a list of discovered subdomains, the total number of SSL/TLS certificates found, and the count of unique subdomains discovered via certificate transparency logs.
Example use cases
Security audit of company infrastructure
“Can you find all the subdomains and SSL certificates for our company domain so we can audit our full attack surface?”
Verify legitimate vs suspicious domains
“I need you to check the certificate history and enumerate subdomains for these domains to make sure they're legitimate and not spoofs of our brand.”
Investigate potential phishing campaigns
“Look up the SSL certificates and hidden subdomains for this domain that's been used in phishing emails targeting our organization.”
Technical details
Endpoint
POSThttps://eltociear-tokenguard.hf.space/data/certsWhen to prefer
Use this endpoint when you need to perform subdomain enumeration or certificate transparency lookups for a specific domain as part of OSINT, security research, or attack surface mapping. Prefer this over general WHOIS lookups when your goal is specifically to discover subdomains and certificate issuance history rather than registrar or ownership information.
Side effects
- Domain not found in certificate transparency logs — returns empty arrays
- Invalid domain format — returns 400 error
- Payment failure via x402 micropayment — request not processed
- Upstream certificate data source unavailable — 503 or timeout
- Rate limiting on repeated rapid calls to the same domain
