Rug-check & launch radar for trading agents: composite honeypot score, EVM+Solana, keyless x402.

Batch rug/safety screen: up to 8 tokens in one call, per-token verdicts (unordered) + summary

Email and domain trust check. Give an email address or a domain, get one risk level (low, medium, high) with plain-language flags and the facts behind them: domain age, registrar, expiry and hold status (RDAP); MX, SPF and DMARC policy; the live TLS certificate; and for emails, syntax, disposable-provider and role-address checks. Judges the domain: does not verify that the mailbox exists and does not check DKIM.

Check whether a domain or email address is trustworthy before you contact it, sign it up, or trust it. Returns a trusted/caution/high_risk/unknown verdict with reasons, based on DNS and mail health (MX, SPF, DMARC), domain age and registrar (RDAP), and disposable, free-provider and typo-lookalike flags. Accepts a domain, URL or email address.

Check whether email addresses are real and safe to send to. Verifies up to 25 addresses per call: syntax, domain MX/A record (including null-MX), disposable-domain, role-account, free-provider and typo checks. Does not perform SMTP/mailbox verification.
