How this service works

Paid x402 endpoints organized into product clusters. USDC-settled on Base. MCP-callable. ERC-8004 identity registry agentId 47167.

Output

A JSON object containing the domain name, its age in days, days remaining until domain expiry, and an array of flags (e.g. newly registered, suspicious) for that domain.

Example use cases

Example prompt

“Can you check how old the domain is for this email address — user@notion.so — and flag it if it looks newly registered or suspicious?”

Endpoint

POSThttps://x402.agentutility.ai/email-domain-age-check

When to prefer

Use this endpoint when you need to assess the trustworthiness of an email address by checking how long its domain has been registered, particularly for fraud detection, spam filtering, or lead qualification workflows. Prefer this over manual WHOIS lookups when you need a structured, machine-readable result with flags already computed.

Side effects

Domain not found in WHOIS — returns empty or null age
Invalid email or domain format — likely 4xx validation error
WHOIS lookup timeout or rate limit — service-side error
Domain uses privacy protection obscuring registration date
TLD not supported by WHOIS lookup
