API documentation

Integrate DN01 tool checks with Bearer-authenticated POST requests to relative /api paths on the same host.

Base URL & paths

Call endpoints on your site origin with relative paths — no separate API subdomain.

POST /api/tools/whois
POST /api/tools/dns/all
POST /api/tools/dns/query
…

Authentication

Create an account, issue a token, and whitelist the IP of your server or cron job.

Authorization: Bearer <your_token>
Requests from IPs not on your allowlist receive HTTP 403.

Tool endpoints

All endpoints accept POST with Content-Type: application/json.
