How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
Returns the domain queried, the DMARC TXT record as a raw string, structured policy fields (p, v, rua, etc.), and DNS source metadata including the provider used, the source URL, fetch timestamp, and expiry time.
Example use cases
Email security audit for vendor domain
“Before we start sending emails on behalf of acmecorp.com, can you look up their DMARC record and tell me whether they have a reject policy in place and where reports get sent?”
Deliverability check before outreach campaign
“I'm about to run a cold outreach campaign from ourfirm.io — can you pull the DMARC record and confirm we have a valid policy configured, not just none or quarantine?”
Phishing risk assessment for a target domain
“Can you check what DMARC policy competitor.com has? I want to know if they're fully protected against spoofing or if they're still on p=none.”
Technical details
Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/security/dmarc?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, parsed DMARC policy rather than a raw DNS TXT lookup — it handles parsing policy tags and provides source provenance metadata. Prefer it for email security audits, deliverability checks, and phishing risk assessments where you need the p= policy value and rua address without building your own DNS parser.
Side effects
- Domain has no _dmarc TXT record — returns empty records array
- Invalid or malformed domain string — schema validation error
- DNS resolution failure — upstream Cloudflare DNS error
- Domain too short or too long — rejected by minLength/maxLength constraints
- Rate limiting or quota exhaustion — HTTP 402 or 429 response
