# SiteCheck Trade & Energy – Air Waybill (AWB) Validator & Carrier Lookup

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability sitecheck-trade-energy-air-waybill-awb-validator-carrier-lookup-4f9a801d
```

Example prompt: Can you check whether the air waybill number 020-12345675 is valid, tell me which airline issued it, and give me the link to track it on their cargo site?

## When to prefer this

Use this endpoint when you need to programmatically validate an air waybill number's check digit, identify the issuing airline from its 3-digit IATA prefix, and obtain the correct cargo tracking URL — without scraping airline sites directly. Prefer this over manual lookup or general-purpose search when processing AWB numbers from invoices, freight documents, or automated logistics workflows. Note: this endpoint does not return live shipment status; for that, the returned tracking link must be followed to the airline's own cargo portal.

## Known failure modes

- Invalid AWB format (not 11 digits or wrong structure) — returns format error
- Check digit mismatch — returns checkDigitValid: false
- Unknown prefix not found in the carrier list — carriers array may be empty or missing
- Malformed query parameter — returns 400-level error
- Upstream track-trace.com carrier list unavailable — may return error or stale data

## How this service works

Air waybill (AWB) check and carrier lookup: validates the 11-digit AWB (3-digit airline prefix + 8-digit serial with the IATA mod-7 check digit), names the issuing airline and its IATA code from the public track-trace.com carrier list, and returns the airline cargo site and a tracking link. It does not read the shipment status itself (airlines publish it only on their own sites).

## Output

A JSON object containing the full formatted AWB, the 3-digit airline prefix, the 8-digit serial, a boolean indicating whether the IATA mod-7 check digit is valid, the issuing airline's name and IATA code, the airline's cargo website URL, a ready-to-use tracking link on track-trace.com, a timestamp of when the check was performed, and a note clarifying that live shipment status must be retrieved from the airline's own site.
