How this service works
Domain format check for Security review: Check a hostname for valid public-domain syntax and normalize IDNs. DNS data only; does not send email or verify that an inbox exists.
Output
Returns a validation result indicating whether the submitted hostname conforms to valid public-domain syntax, along with the normalized (IDNA-encoded) form of the domain if applicable. Does not perform DNS resolution, email delivery, or inbox verification.
Example use cases
Security pipeline domain sanitization
“Before we process this user-submitted hostname 'pаypal.com', can you validate its public-domain syntax and normalize it? I want to catch any IDN homograph tricks in our security review.”
Bulk input validation for onboarding form
“A user just entered 'münchen.de' as their domain in our signup form — can you check if that's a valid public-domain format and normalize it to its canonical IDN form?”
Threat intel domain triage
“We pulled the domain 'évènement-sécurité.fr' from a suspicious email header — can you validate its syntax and normalize it so I can compare it against our blocklist?”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/demand-domain-domain-format-security-review?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, fast syntax check and IDN normalization for a domain string — especially in security review pipelines where you want to detect homograph attacks or malformed hostnames before further processing. Prefer this over full DNS resolution or email verification tools when you only need format validity, not reachability or inbox existence.
Side effects
- Invalid or malformed domain string returns a syntax error or invalid flag
- Private/reserved domain names (e.g. localhost, .local) may be flagged as non-public
- Empty or missing domain field triggers a schema validation error
- Extremely long labels or domains exceeding DNS length limits may be rejected
- Non-string inputs cause input type errors
