# Logen Tracking API & MCP

URL: https://docs.lastscanned.com/carriers/logen

Query live **Logen** (`logen`) package status and scan history in a single synchronous `GET` request or MCP tool call. Logen (로젠택배) is a South Korean domestic parcel carrier; lookups read its public tracking page.

## Overview & Quick Facts

| Property | Value |
|---|---|
| **Carrier slug (`?carrier=`)** | `logen` |
| **Single-package REST endpoint** | `GET https://api.lastscanned.com/v1/track/{trackingNumber}?carrier=logen` |
| **Batch REST endpoint** | `GET https://api.lastscanned.com/v1/track?numbers=N1,N2&carrier=logen` |
| **MCP server (`https://mcp.lastscanned.com`)** | `track_package`, `track_packages`, `list_carriers` |
| **Authentication** | `Authorization: Bearer lsk_live_...` · 1 free keyless lookup/day per IP |

## Tracking Number Formats & Auto-Detection

| Pass | Rule | Examples |
|---|---|---|
| **Pass 1 (`matches`)** | *None* | n/a |
| **Pass 2 (`mayMatch`)** | *None* | n/a |
| **Explicit (`?carrier=logen`)** | 11-digit waybill | `12345678901` |

This shape is shared with other carriers, so always pass `?carrier=logen`. Scan times are Korean local time (`Asia/Seoul`).
