# Centrality

`GET /api/contagion/centrality`

## Request

- Base URL: `https://basisprotocol.xyz` (the document declares no server; this is the origin it was published from)
- URL: `https://basisprotocol.xyz/api/contagion/centrality`
- Auth: none declared

Return the base-rate-normalized entity centrality for ``peg_type``.

The MIM-trap fix: a per-entity bridge score that controls for how often the
entity is INDIVIDUALLY in its own tail, separating structural bridging from
chronic individual stress. Reads the latest run's frozen ``entity_centrality``
rows (written by the slow-cycle calibration pass), entities ordered by
``normalized_centrality`` desc (the base-rate-corrected measure), wrapped in
the same provenance envelope as ``/pairwise`` plus the §6 centrality
disclaimer. ``n_partners`` reports each entity's trustworthy-edge support.
Pre-calibration (no run / no rows) returns an empty set with a null envelope.
