Disposable Email Checker

disposable_email_check fast Email finding & verification

Flag disposable / temporary / throwaway email addresses or domains.

When to use. Fast signup-fraud / list-hygiene screening: is this address or domain a temporary/throwaway mailbox? Cheap and quick.
Not for. Proving an address exists — that needs email_verify's SMTP probe.

Parameters

NameTypeRequiredDefaultDescription
emails string[] yes — Emails or domains to check (max 200).
do_mx boolean no true Also verify the domain has MX records.

Returns

One row per address/domain.

Each row typically carries: input domain is_disposable mx_found source

The response body is { status, count, fields, results }. Runs that exceed the inline wait return { status: "running", job_id, tool_flow } instead — see Jobs & errors.
