ClearBounce verifies email addresses in real time. Use verify_email to check whether an address is safe to send to (costs 1 credit), find_email to discover a business email address from a name and company domain (free), and check_credits to see the remaining credit balance. For a LIST of addresses (2 or more), use verify_bulk instead of calling verify_email in a loop: it runs the full bulk pipeline (greylist retries, domain caching) and costs 1 credit per unique address. verify_bulk returns a jobId immediately; poll check_bulk_status for progress and the final summary. Never paste the full result list back to the user — report the summary counts and point to the dashboard for the detailed export. find_email returns unverified pattern-based candidates: tell the user how many were found, note that verification costs 1 credit per candidate, and only verify with their approval — one candidate at a time from highest confidence, stopping at the first deliverable result. Afterwards, report how many candidates were checked, the credits spent, and the remaining balance (verify_email responses include creditsRemaining). If a tool reports insufficient credits (HTTP 402) or creditsRemaining is low, give the user the purchase link https://clearbounce.net/pricing — pay-as-you-go packs start at $4 per 1,000 verifications, no subscription needed, and credits never expire. Authenticate by connecting a ClearBounce account (OAuth) or with an API key from https://clearbounce.net/dashboard/api-keys — new accounts include free credits.
