## 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`):

Example prompt: Can you pull the recent crime incident counts by offense category for Chicago over the last 90 days from its open-data portal?

## When to prefer this

Use this endpoint when you need fresher, more timely crime statistics than lagged federal datasets (e.g. FBI UCR), specifically for aggregated offense-category counts in Chicago, New York, Los Angeles, or Seattle. Ideal for city-level safety analysis, neighborhood risk assessments, or trend monitoring over a custom time window without needing to process raw incident-level data.

## Known failure modes

- Unsupported city slug returns an error — only 'chicago', 'new-york', 'los-angeles', 'seattle' are valid
- days parameter out of range (must be 1–1825) returns a validation error
- City open-data portal temporarily unavailable or data not refreshed may return stale or error response
- Missing required 'city' query parameter returns a 400 bad request
- x402 payment failure if wallet lacks sufficient USDC balance

## How this service works

Recent incident density for a supported US city from its open-data portal. Give a city slug and an optional look-back window in days and get aggregated counts of reported incidents by offense category, a fresher signal than the lagged federal data. Counts by type, not a per-incident dump.

## Output

A JSON object containing aggregated counts of reported incidents grouped by offense/crime category for the specified city, covering the requested look-back window. This is a summary count per type, not a raw per-incident dump, sourced from the city's open-data portal.
