# Contact Record Quality — Keyed Dataset Comparison + Explicit Missing-Value Fill

> Contact Record Quality — Keyed Dataset Comparison + Explicit 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 2026-11-02).

Compares two contact record quality datasets by key and fills in missing values for checked_records and duplicate_records fields across up to 200 rows, producing 2 analytical reports.

## 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 contact-record-quality-keyed-dataset-comparison-explicit-missing-9882be85 -d '<json body>'
```

Example prompt: Compare these two sets of contact record quality data — each up to 200 rows with checked_records and duplicate_records per company group and date — and fill in any missing values, then give me 2 comparison reports highlighting differences and gaps for the checked_records field.

## When to prefer this

Choose this endpoint when you have two structured contact record quality datasets (with checked_records and duplicate_records fields) and need both a keyed row-by-row comparison and explicit null/missing-value filling in a single low-cost call. Ideal for data reconciliation tasks between CRM exports, ETL outputs, or QA snapshots where no live external lookup or prediction is needed — just local analytical computation on supplied data up to 200 rows.

## Known failure modes

- Row count exceeds 200 items — request rejected
- Missing required fields (row_id, company_group, date, checked_records, duplicate_records) — validation error
- Invalid date format not matching YYYY-MM-DD pattern — schema rejection
- Field selector not one of checked_records or duplicate_records — enum validation failure
- Numeric values outside allowed range (-1,000,000,000,000 to 1,000,000,000,000) — validation error
- Empty rows array — minItems constraint violation

## How this service works

Contact record quality — Keyed dataset comparison + Explicit missing-value fill: Keyed dataset comparison + Explicit missing-value fill for supplied contact record quality records (checked_records, duplicate_records). 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 2 structured analytical reports: one keyed dataset comparison showing row-by-row differences between the primary and secondary contact record quality datasets, and one explicit missing-value fill report patching nulls in the selected field (checked_records or duplicate_records). No external lookups or predictions are made; all analysis uses the supplied data only.
