## 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-road-accidents-by-city-6ae37533
```

Example prompt: Can you pull the road accident statistics for Sofia from the PTP dataset, covering the year 2024, and give me the 50 most recent records?

## When to prefer this

Use this endpoint when you need Bulgarian PTP road accident data broken down by city, especially when filtering by a specific year or date range. Prefer this over generic search if you need structured tabular accident records per Bulgarian municipality.

## Known failure modes

- Missing required 'city' parameter returns a 400 or validation error
- Unknown or misspelled city name may return empty results
- Payment failure or insufficient USDC balance returns HTTP 402
- Date range with no matching records returns empty array
- Very large limit values may be capped or slow
