# Registry Snapshots — Record Quality Audit + Explicit Missing-Value Fill

> Registry Snapshots — Record Quality Audit + 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 2026-10-23).

Audits data quality and fills missing values in registry snapshot records (registered_entities, changed_entities) for up to 200 rows, producing two independent analytical reports.

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 registry-snapshots-record-quality-audit-explicit-missing-value-fill-7a0d694b -d '<json body>'
```

Example prompt: Can you run a record quality audit and fill missing values using median imputation on my registry snapshot data — here are my rows with company_group, date, registered_entities, and changed_entities — I want both reports covering all 200 rows?

## When to prefer this

Choose this endpoint when you need both a data quality audit and missing-value imputation for registry snapshot records in a single call at low cost ($0.01 USDC). It is purpose-built for the registered_entities and changed_entities schema and handles up to 200 rows with two reports per call. Prefer this over generic data-cleaning tools when your data matches the registry snapshot structure (company_group, date, entity counts).

## Known failure modes

- Fewer than 1 or more than 200 rows supplied — request rejected
- Invalid date format (not YYYY-MM-DD) — validation error
- Field or method enum value not recognized — schema validation failure
- All rows have null values for the target field — imputation may return defaults only
- row_id missing or blank — required field error

## How this service works

Registry snapshots — Record quality audit + Explicit missing-value fill: Record quality audit + Explicit missing-value fill for supplied registry snapshots records (registered_entities, changed_entities). 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

Two independent analytical reports: (1) a record quality audit flagging completeness issues, anomalies, and data problems across the supplied rows; and (2) an explicit missing-value fill report showing imputed values for the chosen field (registered_entities or changed_entities) using the specified method (zero, mean, or median). No live lookups or external data are used.
