## 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-record-quality-audit-string-normalisation-numeric-9ceebfba -d '<json body>'
```

Example prompt: Can you run a quality audit, string normalisation, and numeric interval filter on these savings ledger rows — filter by deposit_amount between 5 and 50 — here are the records: row-1 2026-10-01 group-a deposit 10 withdrawal 1, row-2 2026-10-02 group-b deposit 20 withdrawal 2?

## When to prefer this

Choose this endpoint when you need to validate and clean savings ledger data locally — no external lookups or live data required. It is ideal when you need all three analytical operations (quality audit, string normalisation, numeric interval filter) in a single low-cost call on up to 200 rows of deposit/withdrawal records. Prefer it over general-purpose data tools when working specifically with savings ledger schemas (deposit_amount, withdrawal_amount, instrument_group).

## Known failure modes

- Exceeding 200 rows returns a validation error
- Missing required fields (row_id, date, deposit_amount, withdrawal_amount) causes row-level rejection
- Invalid date format (not YYYY-MM-DD) triggers a pattern validation failure
- Minimum greater than maximum causes an interval configuration error
- Empty rows array returns a schema validation error

## How this service works

Savings ledger — Record quality audit + String normalisation + Numeric interval filter: Record quality audit + String normalisation + Numeric interval filter for supplied savings ledger records (deposit_amount, withdrawal_amount). Up to 200 rows; 3 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 3 supplied-data reports for up to 200 rows.

## Output

Returns three independent analytical reports for the supplied savings ledger rows: (1) a record quality audit flagging missing, null, or malformed values; (2) a string normalisation report for the instrument_group and other string fields; and (3) a numeric interval filter report listing rows where the chosen field (deposit_amount or withdrawal_amount) falls within the specified minimum–maximum range.
