When to prefer

Use this endpoint when you need a lightweight, low-cost check of how many emails Hunter has indexed for a domain or company before committing to a full email search or domain search. It's ideal for pre-qualifying outreach lists, estimating database coverage, or filtering companies worth targeting without paying for full contact details.

Side effects

Domain or company not found in Hunter database — returns empty or zero count
Invalid email type filter value (must be 'personal' or 'generic') — may return error
Missing both domain and company fields — request may fail validation
Domain exists but has no indexed emails — returns zero count
Payment failure or insufficient USDC balance — transaction not completed
