## 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 api-strale-io-7e39f95c
```

Example prompt: How much would it cost to ship a 3.5 kg package from Sweden to Germany using PostNord? Give me an estimate across available service levels.

## When to prefer this

Use this endpoint when you need a quick shipping cost estimate across major carriers (PostNord, DHL, UPS) for a given country-to-country shipment and package weight, especially for Nordic/European logistics contexts. Prefer this over generic shipping APIs when PostNord coverage is important.

## Known failure modes

- Unsupported country codes return an error
- Weight outside carrier limits may return no results
- Invalid or missing required parameters (origin_country, destination_country, weight_kg) return a validation error
- Unknown service level string may be ignored or return an error
