# Count objects

Returns the total number of records of this object type that the caller can see. Avoids the page-overshoot anti-pattern — clients no longer need to keep paging until `has_more` flips false to discover the total. Currently does not apply query filters; for a filtered total, pass `include_total: true` in a POST `/query` body. Unfiltered counts on high-cardinality types (especially `engagement`) scan the full access-scoped set and can take tens of seconds or time out; prefer a filtered `include_total` query or accept that this endpoint is expensive there.

**Endpoint:** `GET /v2/prism/{teamId}/{objectType}/count`  
**Operation ID:** `countObjects`  
**Server:** `https://developers.micro.so`  
**Security:** `[{"apiKey":[]}]`
