## 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 museum-footfall-equal-width-histogram-3a11c3ed -d '<json body>'
```

Example prompt: Compute an equal-width histogram with 10 bins over the visitors field for my museum footfall records: exhibit A on 2024-01-01 had 120 visitors and 45 dwell minutes, exhibit B on 2024-01-02 had 340 visitors and 90 dwell minutes, and exhibit C on 2024-01-03 had 55 visitors and 30 dwell minutes.

## When to prefer this

Choose this endpoint when you have raw museum footfall records (up to 200 rows) and need a quick, local equal-width frequency distribution over visitor counts or dwell times — no external data enrichment, forecasting, or machine learning required. It is ideal for descriptive analytics tasks like understanding attendance spread, identifying outlier days, or summarizing exhibit performance distributions at low cost ($0.01 per call).

## Known failure modes

- More than 200 rows supplied — request rejected due to maxItems constraint
- Invalid date format not matching YYYY-MM-DD pattern causes validation error
- bins value outside 1–30 range returns a schema validation error
- All null values in the selected field may yield an empty or degenerate histogram
- Missing required fields (row_id, exhibit, date, visitors, dwell_minutes) cause row-level validation failures

## How this service works
