How this service works
Pay-per-call data endpoints for AI agents. USDC on Base via x402. No account, no API key — one micropayment per call.
Output
A JSON object containing: whether the domain can receive email (canReceive boolean), the domain string, the hosting IP address and a malicious flag for the host, and the domain registration age in days.
Example use cases
Vendor onboarding domain check
“Before we onboard this new supplier, can you check their domain globaltradepartners.com — is it legitimately registered, how old is it, and is the hosting flagged as malicious?”
Phishing domain investigation
“I just got an email from support@paypa1-secure.com — can you look up that domain and tell me if it's newly registered, what IP it's hosted on, and whether it's known to be malicious?”
Cold outreach deliverability check
“We're about to send a campaign to contacts at horizonventures.io — can you check if that domain can actually receive email before we waste the send?”
Technical details
Endpoint
GEThttps://api.polyform.org/v1/domain/due-diligence?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, no-account, pay-per-call domain reputation snapshot that covers email deliverability, hosting safety, and registration age in a single call — especially in agentic workflows where provisioning API keys is impractical and micropayment via USDC on Base is acceptable. Prefer alternatives if you need deep threat intelligence, full WHOIS records, or bulk batch processing.
Side effects
- Domain not found or unresolvable — lookup returns null or empty fields
- Malformed domain input causes a 400 error
- Payment failure via x402 results in a 402 response and no data returned
- Hosting or WHOIS data temporarily unavailable for certain TLDs
- Rate limiting or transient upstream errors return a 5xx response
