🟢bounceban_account
Read verification credit balance and account rate limits without starting verification. Limits and credit balance are shared across the account's API keys.

}🟢bounceban_verify_email(email, disable_catchall_verify, confirm)
Verify one email in regular mode. Costs verification credits on each request, including repeats, and requires confirm:true. Uses the standard API's 15-second result window; returns a final result or a queue/verifying task ID. Read that existing ID with bounceban_single_status later. Never resubmit simply because it is still pending. Basic-only mode can return unknown with score -1 for catch-all/SEG-protected addresses.

}🟢bounceban_single_status(id)
Read an existing single verification ID without spending verification credits. Returns success, verifying or queue. Honor try_again_at when provided; poll no more than 10 times for an ID within 5 minutes, then stop. Results remain available for 90 days. This tool never starts another verification.

}🟡bounceban_create_bulk_verification(emails, name, greylisting_bypass, disable_catchall_verify, confirm)
Submit 1–1,000 emails for regular-mode asynchronous verification. Starts a task and can consume verification credits; requires confirm:true. Check the dashboard before resubmitting after a lost/invalid response. greylisting_bypass:auto balances speed and accuracy; speed may yield more risky results; robust waits longer. No callbacks or automatic polling are configured.

}🟢bounceban_bulk_status(id)
Read progress and aggregate results of an existing bulk task. Does not start verification. Wait between polls and honor account rate limits. importing/verifying status is still pending; finished means the task has ended.

],
"$schema": "https://json-schema.org/draft/2020-12/schema"
}🟢bounceban_bulk_results(id, cursor, state)
Read up to 100 existing email results and a cursor for the next page. Results are retained for 90 days. No verification is started and no following page is fetched automatically. Omit state to get all processed results while a task is running; filtering by state can omit in-progress results. A pending response means wait and check the existing task later.
