## 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-keyed-dataset-comparison-692fa052 -d '<json body>'
```

Example prompt: Compare these two sets of museum footfall records — the first dataset has rows for exhibits 'Ancient Egypt' and 'Modern Art' with visitor counts and dwell times from last month, and the second dataset has the same row IDs but from this month — and give me a side-by-side keyed comparison showing the differences.

## When to prefer this

Choose this endpoint when you have two named, keyed sets of museum footfall records (visitor counts and dwell times by exhibit) and need a structured row-by-row comparison with descriptive statistics — no ML forecasting or external enrichment required. Ideal for before/after analyses, branch comparisons, or seasonal attendance reviews up to 200 records at $0.01 per call.

## Known failure modes

- Mismatched row_id keys between the two datasets result in unmatched rows or partial comparison
- Date strings not matching the YYYY-MM-DD pattern cause validation errors
- Supplying more than 200 rows in either dataset exceeds the item limit and is rejected
- Null numeric values may produce incomplete difference calculations for affected rows
- Empty 'other' dataset array returns a one-sided report with no comparison deltas
