How this service works
Pay-per-call utilities for AI agents over x402, USDC on Base.
Output
Returns a JSON object with the original email, a risk_score (0–100), a verdict (accept / review / reject), a disposable flag, risk_reasons array, has_mail_server flag, and a domain_health object containing SPF record, DMARC record, domain age in days, registrar name, and website_reachable boolean.
Example use cases
Signup fraud gating
“Before activating this new account, run a full email risk check on signup@tempinbox.xyz and tell me whether we should accept, review, or reject it based on the risk score and domain health.”
B2B lead qualification screening
“I have a new inbound lead from cto@startupco.io — can you do a full email risk analysis on it and tell me the risk score, verdict, and whether the domain has valid SPF and DMARC records?”
Phishing sender investigation
“I got a suspicious email from billing@globalfinance-support.com — can you check the full domain health and risk score for that sender address so I can decide if it's legit?”
Technical details
Endpoint
GEThttps://agents.crowdspark.me/v1/email/full?utm_source=zero.xyzWhen to prefer
Choose this endpoint over the basic email_check endpoint when you need both address-level validation AND sender domain intelligence in a single call — especially for fraud screening, signup gating, or lead qualification where SPF/DMARC posture, domain age, and registrar context are needed alongside a quantified risk score and actionable verdict.
Side effects
- Invalid or malformed email address returns an error or empty result
- Unresolvable domain may cause domain_health fields to be null or missing
- Timeout on external domain lookups may result in incomplete domain_health data
- Rate limiting if too many calls are made in a short window
- Payment failure (402) if USDC balance is insufficient
