## 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 zoll-halowerk-taric-duty-rate-evaluator-43b7948d -d '<json body>'
```

Example prompt: What TARIC duty rate applies to commodity code 8471300000 imported from China? The customs value is €5,000 and the source is this EU TARIC regulation published at https://ec.europa.eu/taxation_customs/taric on 2024-06-01.

## When to prefer this

Choose this endpoint when you need to look up a specific published TARIC duty measure for a known commodity code and country of origin with full source transparency, including disclosure of derived values and unavailable fields. It is particularly useful for trade compliance workflows, landed cost calculations, and customs preparation where auditability of the duty rate source matters. Prefer it over generic tariff databases when you need structured, machine-readable output with explicit provenance for each value.

## Known failure modes

- Invalid or unsupported commodity code format returns an error or null rate with commodity_code in unavailable_fields
- Unrecognized origin country ISO code returns an error or null result
- Source URL is unreachable or malformed — validation error on source object
- No published duty measure found for the code/origin combination — rate returned as null with explanation
- Rate is derived rather than directly sourced — disclosed via derivation method field
- Stale or outdated source document may return data with high age warning

## How this service works

Evaluates a published TARIC duty measure for a commodity code and origin. Missing facts are returned as null and named in unavailable_fields where applicable. Derived values disclose their method; source-backed values disclose source, time window and age. This is neither legal advice nor customs advice.

## Output

Returns the applicable TARIC duty rate percentage for the supplied commodity code and origin country, along with source attribution (URL, title, publication date), data age and time window, the method used for any derived values, and a list of unavailable_fields for any facts that could not be determined. Explicitly notes that results are not legal or customs advice.
