# Data Reconciliation — Keyed Dataset Comparison with Missing-Value Fill

> Data Reconciliation — Keyed Dataset Comparison with Missing-Value Fill is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-19).

Compares two keyed datasets row-by-row, identifies discrepancies between source_total and target_total, and fills explicit missing values, producing two analytical reports for up to 200 rows.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 data-reconciliation-keyed-dataset-comparison-with-missing-value-fill-0c8eaf0b -d '<json body>'
```

Example prompt: Can you reconcile these two datasets for me? I have up to 200 rows each with a row_id, dataset_group, date, source_total, and target_total — compare them side by side keyed by row_id and fill any missing values, then give me two reports showing where source_total figures diverge.

## When to prefer this

Choose this endpoint when you need a lightweight, low-cost ($0.01 USDC) batch reconciliation of two keyed datasets up to 200 rows each, with explicit missing-value handling and two independent analytical reports — particularly when no external data lookup, prediction, or live enrichment is needed and all data is supplied by the caller.

## Known failure modes

- Exceeding 200 rows triggers a validation error
- Missing required fields (row_id, dataset_group, date, source_total, target_total) cause schema rejection
- Dates not matching YYYY-MM-DD pattern are rejected
- Values outside ±1,000,000,000,000 range are rejected
- row_id longer than 80 characters is rejected
- Submitting fewer than 1 row causes an error

## How this service works

Data reconciliation — Keyed dataset comparison + Explicit missing-value fill: Keyed dataset comparison + Explicit missing-value fill for supplied data reconciliation records (source_total, target_total). 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 per call: a keyed row-by-row comparison report showing differences between source_total and target_total across both supplied datasets, and an explicit missing-value fill report identifying and resolving null entries — all computed locally with no external lookups, covering up to 200 rows per dataset.
