API reference
The datafetch.wtf REST API returns structured intelligence for emails, phones, usernames, domains, IPs and gaming identifiers. Every request is authenticated with an API key and metered against your plan.
Upstream reference: domain intelligence and the extended endpoint reference are documented at coresint.xyz.

Send your key on every request. Keys are created in the console and shown once.
# curl curl -s https://api.datafetch.wtf/api/v1/health # authenticated search curl -s -X POST https://api.datafetch.wtf/api/v1/search \ -H "Content-Type: application/json" \ -H "X-Api-Key: $DATAFETCH_API_KEY" \ -d '{"module":"email","query":"[email protected]"}'
Always call the API over HTTPS. Keys are stored hashed — rotate them from Dashboard → API keys if one leaks.
Endpoints
Domain lookup
Domain and infrastructure intelligence (WHOIS, DNS, subdomains, certificates and hosting history) is provided through the coresint upstream. The console's Domain lookup module targets it directly.
# console → Network & domains → Domain lookup
