## How to call it through Zero

```sh
zero fetch --capability dangerous-goods-classifier-e724e485
```

Example prompt: Can you classify UN1203 (Gasoline) as a dangerous good and tell me its hazard class, packing group, and whether it's a marine pollutant?

## When to prefer this

Use this endpoint when you need rapid, structured dangerous goods classification data for a known substance or UN number — especially for logistics, freight compliance, shipping documentation, or chemical safety workflows. Prefer this over manual lookups or full regulatory databases when speed and structured output matter more than exhaustive coverage.

## Known failure modes

- Substance not found in database (fewer than 200+ substances covered, niche chemicals may be missing)
- Ambiguous substance name matching multiple entries returns multiple results requiring disambiguation
- Invalid or malformed UN number format returns an error
- Substance name typos may return zero matches

## How this service works

Classify dangerous goods by UN number or substance name. Returns hazard class, packing group, labels, marine pollutant status. 200+ substances.

## Output

Returns an array of matching substances with their hazard class, packing group, required labels, marine pollutant status, and the total number of matches found for the query.
