# Savings Ledger Daily Sum Series and Keyed Dataset Comparison

> Savings Ledger Daily Sum Series and Keyed Dataset Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Computes a daily sum time series and a keyed dataset comparison for savings ledger rows (deposit_amount, withdrawal_amount) — two analytical reports from up to 200 supplied rows.

## 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-daily-sum-series-and-keyed-dataset-comparison-029221a4 -d '<json body>'
```

Example prompt: I have two sets of savings ledger records (up to 200 rows each, with deposit_amount and withdrawal_amount per date and instrument group) — can you run a daily sum series on deposit_amount and compare the two datasets by key to see where they differ?

## When to prefer this

Choose this endpoint when you have pre-collected savings ledger data (up to 200 rows) and need both a daily aggregation time series and a row-keyed comparison between two datasets in a single low-cost call. Ideal for reconciliation tasks or trend analysis where no live data fetching, predictions, or external enrichment are needed — purely local analytical computation on supplied rows.

## Known failure modes

- Fewer than 1 row supplied — minItems constraint violated
- More than 200 rows supplied — maxItems constraint exceeded
- Missing required fields (row_id, instrument_group, date, deposit_amount, withdrawal_amount) on any row
- Invalid date format (must match YYYY-MM-DD pattern)
- field enum value not 'deposit_amount' or 'withdrawal_amount'
- Numeric values outside allowed range (-1,000,000,000,000 to 1,000,000,000,000)
- Payment not fulfilled — x402 micropayment of 0.01 USDC required

## How this service works

Savings ledger — Daily sum series + Keyed dataset comparison: Daily sum series + Keyed dataset comparison 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

Returns two reports: (1) a daily sum series aggregating the chosen field (deposit_amount or withdrawal_amount) across all rows by date, and (2) a keyed dataset comparison identifying differences between the primary and secondary ledger datasets row by row. No external lookups or predictions are made — results are derived entirely from supplied data.
