## 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 donation-campaign-records-grouped-numeric-summary-1b180fe8 -d '<json body>'
```

Example prompt: I have 4 donation campaign records for two groups — 'Spring Drive' and 'Year-End Appeal' — with dates, donation counts, and amounts. Can you group them by campaign and give me a numeric summary of the 'amount' field?

## When to prefer this

Choose this endpoint when you have up to 200 donation campaign records already in hand and need fast, local grouped descriptive statistics (no external data needed). It is ideal for nonprofit analysts, fundraising teams, or agent workflows that need to compare campaign performance at low cost ($0.01 USDC). Prefer it over general-purpose analytics platforms when you need a lightweight, pay-per-call summary with no setup, or when campaign-specific grouping by name is the primary analytical need.

## Known failure modes

- Empty or missing 'rows' array returns an error
- More than 200 rows submitted — request rejected due to maxItems constraint
- Invalid date format (not YYYY-MM-DD) causes validation failure
- Missing required fields (row_id, campaign, date, donations, amount) per row causes rejection
- Field selector not one of 'donations' or 'amount' causes enum validation error
- Null values in the selected numeric field may affect aggregate calculations
