Fiber AI Combined Search Count

Use this endpoint when you need to know the size of a result set before fetching the actual records — ideal for pagination planning, quota checking, or validating that search filters are narrow enough to be actionable. Prefer this over running a full search when you only need counts, not the underlying contact or company data.

• Invalid or malformed filter parameters return a 400 error
• Missing required filter fields cause validation errors
• Overly broad filters with no constraints may time out or return unexpectedly large counts
• Authentication errors return 401 if credentials are missing or invalid
• Rate limiting may return 429 if too many requests are sent in quick succession
