# YDH Tracking API & MCP

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

Query live **YDH** (`ydh`) package status and scan history in a single synchronous `GET` request or MCP tool call. `lastscanned` auto-detects numbers shaped `YDH` + 10 digits + 2 letters.

## Overview & Quick Facts

| Property | Value |
|---|---|
| **Carrier slug (`?carrier=`)** | `ydh` |
| **Brand & service aliases** | YDH, YDH Express, YDH Cross Border, Yida (義達), ydhex.com |
| **Category** | Chinese cross-border e-commerce forwarder |
| **Single-package REST endpoint** | `GET https://api.lastscanned.com/v1/track/{trackingNumber}` |
| **Batch REST endpoint** | `GET https://api.lastscanned.com/v1/track?numbers=...` |
| **MCP server (`https://mcp.lastscanned.com`)** | `track_package`, `track_packages`, `list_carriers` (`claude mcp add --transport http lastscanned https://mcp.lastscanned.com`) |
| **Authentication & pricing** | `Authorization: Bearer lsk_live_...` · **1 free keyless lookup/day per IP** · **Free tier** (5 unique numbers/day, $0) · **Pro** ($4.99/mo for 1,000 unique numbers, unlimited re-polls, $0.015/extra) |

## Tracking Number Formats & Auto-Detection

| Pass | Rule / Regex | Examples |
|---|---|---|
| **Pass 1 (`matches`)** | `/^YDH\d{10}[A-Z]{2}$/` | `YDH0004849752AZ`, `YDH3001564927YQ` |
| **Pass 2 (`mayMatch`)** | *None* | n/a |

YDH only claims its own `YDH…` shape, so `?carrier=ydh` is normally not needed.

## Notes

- **Source**: the `track.ydhex.com` query form (server-rendered HTML), read directly from the Worker; no bot wall.
- **Wording**: scan text is whatever YDH prints, a mix of Chinese, Japanese and English. `status` is derived from it, and `description` is passed through as is.
- **Times**: scans print local time with no zone, so only `localTime` is set (`timestamp` is `null`).
- **Unknown numbers**: YDH answers "no record", returned as a `404 not_found`.
