## 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 sscc-18-logistics-unit-code-validator-b3d07904
```

Example prompt: Can you validate this SSCC-18 code for me — 006141411234567890 — and tell me if the format and check digit are correct?

## When to prefer this

Use this endpoint when you need to verify SSCC-18 logistics unit codes specifically, as opposed to GTIN product codes, ISO 6346 container numbers, or IMO ship numbers. It is purpose-built for GS1 pallet/logistics-unit serial shipping container codes and correctly applies GS1 check digit rules for the 18-digit format.

## Known failure modes

- Missing or empty 'code' query parameter returns an error
- Non-18-digit input flagged as invalid format
- Invalid check digit returns a failed validation response
- Non-numeric characters in the code cause a format error
- Network timeout or upstream service unavailability

## How this service works

Validate an SSCC-18 logistics-unit serial shipping container code.

## Output

Returns a validation result indicating whether the SSCC-18 code is correctly formatted and has a valid GS1 check digit, along with any specific error details if the code is invalid.
