Domain Verification
Cryptographic domain proof in minutes. DNS TXT, HTTP file, or admin email verification — the DNS and HTTP checks cloud platforms and certificate authorities use. Essential for vendor onboarding, partnership verification, and business transactions.
Why Automated Domain Proof?
Vendor onboarding usually means webmaster email threads and screenshots — or yet another verification supplier. The platforms standardised DNS challenges years ago; Proof Holdings automates that standard and hands you portable evidence.
Manual Checks or Another Vendor
Chase the webmaster yourself, or contract a point domain-verification service — either way the answer goes stale.
Webmaster threads and WHOIS squinting
Days of back-and-forth to answer one question: do they actually control the domain?
Screenshots as evidence
Unverifiable and instantly stale — control can change the day after the check.
A point service is one more supplier
Specialised domain-verification vendors exist, but that's another contract and another headache for a single check.
Every partner audits differently
No standard artifact — each counterparty reinvents the checklist from scratch.
Domain Verification with Proof Holdings
The same challenge methods the big platforms use, automated end to end, ending in a signed proof.
The industry-standard methods
DNS TXT, HTTP file, or admin email — the DNS and HTTP checks cloud platforms and certificate authorities use.

A signed, portable proof
Proof token plus verified_data — evidence any counterparty can check, re-runnable with one API call.
One supplier, every asset
The same integration verifies emails and phone numbers — social accounts and wallets are planned.
Industry-standard domain control verification
Create Verification
Call our API with the domain name. We generate a unique verification token and instructions.
User Proves Ownership
Domain owner adds a DNS TXT record (manually or auto-created via registrar), hosts a file, or confirms via webmaster email.
Proof Generated
We verify the record/file exists and return a cryptographic proof of domain control.
Automatic DNS Provider Detection
We detect your DNS provider automatically from nameserver records. For supported providers, we can create the verification TXT record for you - no manual DNS editing required.
