# Interfaces

Public contracts for ingestion and APIs.

Lists the public event and API contracts.

### Event Interfaces

IntelFactor supports secure ingestion of structured inspection events using authenticated channels.

Interfaces are:

* Schema-versioned
* Backward-compatible
* Designed for operational resilience

### APIs

Public APIs provide read access to:

* Inspection history
* Evidence references
* Aggregated metrics

Write access is restricted and controlled.
