GET/v1/tacsi/pillars

TACSI Pillar Series

Returns a single pillar sub-index series (one of impact, momentum, presence, reach, sentiment) for one entitled sector. Same aggregate-only privacy model as the weekly feed: k-anonymized cohorts of at least 50 distinct entities, differential privacy at publication, banded cohort sizes only, and no individual account data. A Pillar Feed for the exact sector and pillar satisfies this endpoint, as does any broader entitlement (Sector Feed or Full Database).

Bearer token required. A Pillar Feed for the sector and pillar, or a broader institutional subscription.
