      description: 'Filter results by field values using the syntax `filter[<field>][<op>]=<value>`.


        Operators by field type:

        - **string**: `eq`, `ne`, `in`, `notIn`, `isNull`, `isNotNull`

        - **number**: `eq`, `ne`, `gt`, `gte`, `lt`, `lte`, `in`, `notIn`, `isNull`, `isNotNull`

        - **boolean**: `eq`, `ne`, `isNull`, `isNotNull`

        - **date**: `eq`, `ne`, `gt`, `gte`, `lt`, `lte`, `isNull`, `isNotNull`


        For `in` and `notIn`, provide comma-separated values: `filter[tag_id][in]=a,b,c`.

        For `isNull` and `isNotNull`, the value is ignored.


        Multiple filters are combined with AND.


        Examples:

        - `filter[ad_unit_id][eq]=unt_abc123`

        - `filter[ad_unit_name][in]=Leaderboard,Rectangle`

        - `filter[is_deleted][eq]=false`'

        Limits:

        - `POST /auth/token`: 20 req/min per `client_id` (app), plus WAF per-IP limit

        - `/events/*` and `/dimensions/*`: burst limit of 100 req / 10s per client (app)

        - All authenticated routes: WAF 60 req/s per `x-client-id` (5-minute window)

        - `/ip/*` routes: WAF elevated tier (app burst limit does not apply)


        App-level limits can be disabled via `PULSAR_APP_RATE_LIMITS=0|false|off` (WAF still applies).'
