Domain Collection - FullHunt API Documentation

Look up a domain

GET /api/v1/nexus/domain-collection/lookup?domain={domain}

curl --get "https://fullhunt.io/api/v1/nexus/domain-collection/lookup" \
  -H "X-API-KEY: $FULLHUNT_API_KEY" \
  --data-urlencode "domain=example.com"

Search by company

GET /api/v1/nexus/domain-collection/company-lookup?query={company}

curl --get "https://fullhunt.io/api/v1/nexus/domain-collection/company-lookup" \
  -H "X-API-KEY: $FULLHUNT_API_KEY" \
  --data-urlencode "query=Example Corporation"

The company route uses the query parameter for the company name. Both routes are limited to 60 requests per minute and deduct one Nexus credit after a validated successful request.

Use the relationships safely

Organization names, subsidiaries, acquisitions, historical domains, and shared infrastructure create ambiguity. Preserve source fields and assign a relationship state such as candidate, corroborated, or verified before using a domain in monitoring or due-diligence output.
