## 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 fbi-ucr-nibrs-crime-rate-benchmark-677d9e5d
```

Example prompt: What's the FBI baseline crime rate for aggravated assault in Texas over the last 3 years — I need it per 100,000 people so I can anchor a local safety score.

## When to prefer this

Use this endpoint when you need a deterministic, authoritative baseline crime rate from official FBI UCR/NIBRS data to anchor, compare, or contextualize a local crime score. Prefer this over AI-generated estimates or non-FBI sources when accuracy and reproducibility matter. Ideal for safety scoring pipelines, real estate analysis, insurance underwriting, or public policy research.

## Known failure modes

- Invalid or unsupported offense enum value returns an error
- Invalid state abbreviation (not a 2-letter US state code) returns an error
- Years parameter outside 1–10 range returns a validation error
- No data available for a very recent reporting year may return incomplete results

## How this service works

National or state baseline crime rates for an offense and window from public FBI UCR and NIBRS data. Give an offense and an optional 2-letter state and get the annualized rate per 100,000 people by year, for anchoring a local score. Deterministic, no AI.

## Output

Returns a time-series of annualized crime rates per 100,000 people broken down by year for the requested offense, scoped to either a specific US state or the national level, sourced deterministically from public FBI UCR/NIBRS data.
