# Savings Ledger Numeric Interval Filter and Two-Measure Correlation

> Savings Ledger Numeric Interval Filter and Two-Measure Correlation 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).

Filters savings ledger rows by a numeric range on deposit or withdrawal amount and computes a two-measure correlation between deposit_amount and withdrawal_amount, returning two analytical reports for up to 200 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-numeric-interval-filter-and-two-measure-correlation-1e1d8889 -d '<json body>'
```

Example prompt: I have my savings ledger records with deposit and withdrawal amounts — can you filter rows where deposit_amount is between 10 and 500, then run a two-measure correlation between deposits and withdrawals across all 150 rows and give me the two reports?

## When to prefer this

Use this endpoint when you have savings ledger data (up to 200 rows) already in hand and need both a numeric range filter on deposit or withdrawal amounts AND a correlation analysis between the two measures in a single paid call. It is ideal for offline or batch analytical scenarios where no live data lookup is needed and cost must be kept minimal ($0.01 for two reports). Prefer this over general-purpose analytics platforms when working specifically with savings ledger schemas (deposit_amount, withdrawal_amount, instrument_group) and needing a lightweight, self-contained computation.

## Known failure modes

- More than 200 rows submitted — request rejected or truncated
- Missing required fields (row_id, date, deposit_amount, withdrawal_amount, instrument_group) cause validation errors
- Date format not matching YYYY-MM-DD pattern causes schema rejection
- minimum greater than maximum produces empty filter result or error
- Non-numeric values in deposit_amount or withdrawal_amount fields
- Payment of 0.01 USDC not completed via x402 protocol — request blocked

## How this service works

Savings ledger — Numeric interval filter + Two-measure correlation: Numeric interval filter + Two-measure correlation 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 analytical reports: (1) a filtered list of savings ledger rows whose specified field (deposit_amount or withdrawal_amount) falls within the given numeric interval [minimum, maximum], and (2) a two-measure correlation coefficient and related statistics between deposit_amount and withdrawal_amount computed over the supplied rows. Both reports are generated locally from the submitted data with no external lookups.
