## 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 datanexusai-ptp-most-deadly-road-locations-fb800ce6
```

Example prompt: What were the most deadly road accident locations in 2020 according to PTP data? Give me the top 5 clusters.

## When to prefer this

Use this endpoint when you need ranked, clustered fatal road accident locations for a specific calendar year from the PTP dataset. Prefer this over generic traffic APIs when you need structured hotspot rankings with fatality data rather than raw incident records or aggregate statistics.

## Known failure modes

- Year out of range or no data available for that year returns empty result or 404
- Missing year path parameter returns 422 validation error
- Payment not provided or insufficient USDC results in 402 Payment Required
- Invalid year format (non-integer) returns 400 Bad Request
- Limit parameter set to 0 or negative may return empty or error response
