# Your own call history across REST + MCP (self-serve audit trail): timestamp, endpoint/tool, redacted params, status, la…

`GET /api/v1/usage`

## Request

- Base URL: `https://siliconanalysts.com`
- URL: `https://siliconanalysts.com/api/v1/usage`
- Auth: none required

Your own call history across REST + MCP (self-serve audit trail): timestamp, endpoint/tool, redacted params, status, latency, payload size, the request_id matching the X-Request-Id header your client received, and trace_id when your client sent a W3C traceparent header (we echo traceparent/tracestate on every response and store the trace-id — join our audit trail against your own distributed traces). Requires an API key — anonymous callers have no identity to export.

## Query parameters

- `window` string
- `limit` string
- `before` string

## Response `200`

Successful response

- Envelope: Shared response envelope. Endpoint-specific payloads ride in `data`; `meta` carries provenance, freshness, and pagination hints.
  - `success` boolean
  - `data` object
  - `meta` object
