How this service works
Get count of profiles matching search filters. Use to estimate result sizes before running a full search.
Output
A numeric count of how many people profiles in the Fiber AI database match the provided search filters, allowing the agent to estimate result volume before committing to a full paginated search.
Example use cases
Validate ICP filter before pulling
“Before I spend credits on a full search, can you check how many people on Fiber AI match my ideal customer profile — Head of Sales at SaaS companies in the US with 100 to 1000 employees?”
Check if filters are too narrow
“I want to target DevOps engineers at fintech startups in New York with under 200 employees — can you first check how many results that would return on Fiber AI so I know if I need to broaden my filters?”
Estimate audience size for campaign
“We're planning an outreach campaign for CTOs at Series A and Series B companies in the healthcare industry — can you get a quick count from Fiber AI so we know how large that audience is before we pull the actual contacts?”
Technical details
Endpoint
POSThttps://mpp.orthogonal.com/fiber/v1/people-search/count?utm_source=zero.xyzWhen to prefer
Use this endpoint before running a full Fiber AI people search to estimate result sizes, validate filter combinations, and avoid wasting money on searches that return too few or too many results. Prefer this over the full search endpoint when you only need the count, not the actual profiles.
Side effects
- Invalid or unsupported filter fields return a 400 error
- Authentication failure returns 401 if API credentials are missing or invalid
- Overly broad filters may return very large counts that are less actionable
- Overly narrow filters return a count of 0 with no profiles matched
- Rate limiting or quota exhaustion may return a 429 error
