## 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 savings-ledger-numeric-distribution-and-grouped-numeric-summary-1a542206 -d '<json body>'
```

Example prompt: I have 150 rows of savings ledger data with deposit_amount and withdrawal_amount fields grouped by instrument — can you run both a numeric distribution and a grouped numeric summary on the deposit_amount field for me?

## When to prefer this

Choose this endpoint when you have savings ledger data (up to 200 rows) and need both a numeric distribution and a grouped numeric summary in a single low-cost call. It is ideal for offline or batch analytical workflows where no live data lookup or external prediction is needed and you want two statistical reports on deposit or withdrawal amounts for $0.01.

## Known failure modes

- Rows array empty or missing — minItems:1 violated
- More than 200 rows submitted — maxItems:200 exceeded
- Missing required row fields (row_id, instrument_group, date, deposit_amount, withdrawal_amount)
- Date field does not match YYYY-MM-DD pattern
- Invalid field enum value (must be deposit_amount or withdrawal_amount)
- Payment of 0.01 USDC not provided — x402 payment required

## How this service works

Savings ledger — Numeric distribution + Grouped numeric summary: Numeric distribution + Grouped numeric summary for supplied savings ledger records (deposit_amount, withdrawal_amount). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.

## Output

Two analytical reports: (1) a numeric distribution showing how values of the chosen field (deposit_amount or withdrawal_amount) are spread across ranges/bins, and (2) a grouped numeric summary aggregating statistics for the same field broken down by instrument_group. Both reports are computed locally from the supplied rows.
