# KEX Express Thailand (Kerry Express) Tracking API & MCP

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

Query live **KEX Express Thailand** (`kex`) package status and scan history in a single synchronous `GET` request or MCP tool call. KEX numbers are not auto-detected, so pass `?carrier=kex`. `lastscanned` returns a normalized `TrackingResult` JSON payload, with no KEX account or API key.

## Overview & Quick Facts

| Property | Value |
|---|---|
| **Carrier slug (`?carrier=`)** | `kex` |
| **Brand & service aliases** | KEX Express, KEX Express Thailand, Kerry Express Thailand, `th.kex-express.com` |
| **Category** | Thai domestic courier |
| **Single-package REST endpoint** | `GET https://api.lastscanned.com/v1/track/{trackingNumber}?carrier=kex` |
| **Batch REST endpoint** | `GET https://api.lastscanned.com/v1/track?numbers=KEX1234567890,...&carrier=kex` |
| **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) · **HTTP 402 Stripe MPP** ($0.50 for 25-number `lsk_pack_` key or $0.02/number in USDC on Tempo) |

## Tracking Number Formats & Auto-Detection

| Pass | Rule | Check digit | Examples |
|---|---|---|---|
| **Pass 1 (`matches`)** | *None* | n/a | n/a |
| **Pass 2 (`mayMatch`)** | *None* | n/a | n/a |
| **Explicit (`?carrier=kex`)** | The consignment number printed on the KEX label or in the sender's message | n/a | `KEX1234567890` |

KEX numbers come in several shapes that other carriers share, so `?carrier=kex` is required.

### Normalized `TrackingResult` JSON response

```json
{
  "carrier": "kex",

## Notes

- Scan times are Thailand time, returned with a UTC `timestamp` and the scan's `localTime`.
- `delivered` is set from KEX's own codes (`POD` and `400`), `returned` from `401`, and `out_for_delivery` from the `060` family.
- When KEX gives a due date it is returned as `estimatedDelivery`.
- Some KEX proofs of delivery (signature, photo) are only shown in the KEX app and are not returned.
