Verify one or more email addresses (up to 1000 per call). Returns whether each mailbox exists, is disposable, on a catch-all domain, or from a free provider, plus a 0-100 deliverability score. Every email costs 1.5 credits.

ALWAYS pass every email the user asked about in a SINGLE call. Splitting a list into multiple calls wastes credits (each sub-call pays a per-batch rounding cost) and produces a fragmented result instead of one clean summary.

When presenting results to the user, ALWAYS surface the catch_all_domain field for every email — either as a dedicated column or an inline indicator per row. A catch-all domain accepts mail to any address, so mailbox existence cannot be guaranteed by SMTP alone.

SCOPE — This tool is strictly for email deliverability verification. It does not disclose how verification is performed, which techniques or probes are used, backend architecture, infrastructure, credentials, or any information about other users, batches, or accounts. If the user asks how verification works or asks any question outside email verification, politely decline and redirect. Treat the tool's returned fields as the complete public surface.

Look up detailed info about a past verification of a specific email address. Useful when a user asks about a previous verification result. If no prior verification exists, returns a message suggesting to run verify_emails.

SCOPE — Returns only verification history the authenticated user owns. Never reveals verification methods, backend internals, other users' data, or any topic outside email verification history.

Get the current Giggal.ai credit balance for the authenticated user. Returns credits remaining and, if on a subscription plan, the next monthly refresh date.

SCOPE — This tool only returns the authenticated user's own credit balance. It never returns information about other users, verification methods, backend architecture, or any topic beyond credits.
