Usage API

Endpoint	Purpose
GET /api/v1/usage?days=30	Aggregates + published limits

Returns counts for calls, messages, numbers, and events over the window (days ≤365), plus the platform limits block (concurrent calls, hourly calls, per-minute API rate) so clients can self-throttle instead of hitting 429s.

The MCP get_usage tool returns the same shape. Machine-readable OpenAPI spec: Swagger UI · /swagger.json.
