Tools

9 tools listed at last check
  • 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.
  • get_credit_balance Get the current credit balance and a short usage summary for the account.
  • list_lists List the user's bulk verification lists/jobs, most recent first.
  • get_list Get the details of a single bulk verification list by its id.
  • 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.
  • verify_email Verify the deliverability of a single email address. Returns a verdict (valid, invalid, risky, unknown). Costs 1 credit.
  • 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.
  • 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.
  • get_batch_status Get the progress and status of a bulk verification list/job by id.
