Owner verification

Not yet verified. Verifying proves you control this server and is free, permanently — it never changes a published score.

Tools

estimate_cost
Estimate the credit cost of a verification before running it, and whether the user can afford it. Provide either a count of emails, a list_id to re-verify, or an operation ('single'/'finder'). Always quote this before proposing anything billable.
shallow
explain_result
Explain what a verification status or reason means in plain English, with a send recommendation. Covers valid, invalid, catch-all/accept-all, unknown, greylisted, disposable, role, free, spam-trap, abuse, do-not-mail, no-mx, disabled, and network. Use when a user asks what a result means.
shallow
get_api_key
Get your own free API key for this server (no account needed; 25 email verifications per day). Optional: the verification tools already work without a key on a shared trial. Returns the key once — reconnect with 'Authorization: Bearer <api_key>' for your own quota and the list tools.
shallow
get_batch_status
Get the progress and status of a bulk verification list/job by id.
shallow
get_credit_balance
Get the current credit balance and a short usage summary for the account.
shallow
get_list

shallow
list_lists
List the user's bulk verification lists/jobs, most recent first.
shallow
verify_batch
Verify a batch of email addresses (up to 25 per call with an agent key). Returns per-email verdicts and saves a list. Costs 1 credit per email.
shallow
verify_email
Verify the deliverability of a single email address. Returns a verdict (valid, invalid, risky, unknown). Costs 1 credit.

Tool count and median score across every tool in this server’s corpus — honest in a way a single cherry-picked tool’s badge wouldn’t be.
