Look up one domain

Everything we hold for a single domain: detected technologies, hosting, DNS posture and launch metadata. Returns {"found": false} for a domain outside the corpus, which is not an error. The corpus is newly launched sites, so an established domain will usually not be present.

Requires the lookup scope. Available on: indie, pro, firehose.

Query parameters

domainstring required

Domain or host, without scheme.

includestring

Enrichment blocks to attach: any of infra, email, quality, agent, contact, or all. Note that email is this API's DMARC/MTA-STS posture block, while contact is the site's own published contact route and needs the contacts scope.

min_confidencenumber

Shorthand setting both floors below. The two per-dimension parameters win where both are supplied.

min_category_confidencenumber

Category floor, 0 to 1. No floor by default: every category we hold is served with its confidence. Set 0.9 to match the public site.

min_country_confidencenumber

Country floor, 0 to 1. No floor by default. Set 0.45 to match the public site; 0.9/0.45 together reproduce the figures published on /data.

Response

Success.
