crt.sh Certificate Transparency Scraper — Pay Per Result

Scrape Certificate Transparency records from crt.sh JSON (?q=&output=json). HTTP-only — no browser.

Store search keywords: crt.sh scraper · certificate transparency · CT logs · subdomain discovery · SSL certificates

Why this Actor

Pain	What we do
Manual CT lookups	Batch domains → structured rows
Duplicate noise	Deduped by certificate `id`
Opaque failures	Empty queries → not charged

Example input

{
  "domains": ["example.com", "%.example.com"],
  "excludeExpired": true,
  "maxItems": 200
}

Endpoints

URL	Notes
`https://crt.sh/?q={domain}&output=json`	Official JSON export

Output fields

Field	Description
`id`	crt.sh certificate id
`issuerName`	Issuer DN
`commonName`	CN
`nameValue`	SAN / name blob (may be multiline)
`notBefore` / `notAfter`	Validity window
`serialNumber`	Serial
`url`	`https://crt.sh/?id={id}`
`scrapedAt`	Scrape time

Pricing

Pay-per-event for each delivered certificate row.

Empty / failed queries → not charged
Exact $/1k on the Store tab (~$0.50–1/1k)

Limitations (honest)

crt.sh can be slow or overloaded; use requestDelayMs and optional proxy
Large domains return thousands of rows — cap with maxItems
No pagination API; one JSON blob per query
Wildcard syntax follows crt.sh conventions (%.example.com)
