Domains

domains

Optional

Domains to look up, one per line (commas and spaces also separate entries). Bare domains (example.com), subdomains (mail.example.com), URLs (https://www.example.com/page), email addresses (jane@example.com) and IDN names (münchen.de) are accepted. A leading www. is removed so email checks run on the mail domain. Invalid entries are listed in the results with an error and are not charged.

Type:array

Example:

[
  "apify.com",
  "github.com",
  "google.com",
  "bbc.co.uk"
]

Extra DKIM selectors

dkimSelectors

Optional

DKIM keys can only be found if you know the selector. These common selectors are always checked: google, selector1, selector2, default, k1, s1, mail, dkim. Add your own here, for example the one in the DKIM-Signature header (s=) of an email you received.

Type:array

Default:

[]

Checks to run

checks

Optional

Leave everything selected for a full audit. Switch off checks you do not need to make runs faster. Only selected checks affect the grade.

Type:string[]

Default:

[
  "dns",
  "spf",
  "dmarc",
  "dkim",
  "dnssec",
  "mtaSts",
  "bimi",
  "ssl",
  "headers",
  "redirect"
]

Include WHOIS (registrar, created and expiry dates)

includeWhois

Optional

Adds registrar, creation date, expiry date, days to expiry and domain age for the registrable domain. Uses the registry's RDAP API, or port-43 WHOIS for TLDs without RDAP (.io, .co, .de, .it, ...). Some registries (.de, .ch, .es) publish little or no data, then the whois field explains why. Lookups are throttled per registry and cached per run, so big lists of one TLD take longer. Free, no extra charge.

Type:boolean

Default:true

Max WHOIS lookups per run

maxWhoisLookups

Optional

Safety cap for WHOIS lookups in one run. Subdomains of the same domain share one lookup. Domains past the cap are still audited, only without WHOIS data. Registries rate limit WHOIS, so keep this modest for very large lists.

Type:integer

Minimum:1

Maximum:10000

Default:1000

Max concurrency

maxConcurrency

Optional

How many domains to audit in parallel.

Type:integer

Minimum:1

Maximum:50

Default:10

Network timeout (seconds)

timeoutSecs

Optional

Maximum wait for each TLS or HTTP connection. A whole domain audit is capped at 45 seconds.

Type:integer

Minimum:3

Maximum:60

Default:10
