# Registry Snapshots — String Normalisation + IQR Outlier Flags

> Registry Snapshots — String Normalisation + IQR Outlier Flags is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Normalises string fields and flags IQR-based outliers in registry snapshot data (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-string-normalisation-iqr-outlier-flags-c9587b02 -d '<json body>'
```

Example prompt: I have a set of registry snapshot rows with registered_entities and changed_entities counts across several company groups — can you run string normalisation and IQR outlier detection on the registered_entities field for up to 50 rows and give me both reports?

## When to prefer this

Choose this endpoint when you have structured registry snapshot data with registered_entities or changed_entities counts and need both string normalisation and IQR-based outlier detection in a single low-cost call (up to 200 rows). It is ideal for pre-reporting quality checks, anomaly detection pipelines, or compliance data hygiene tasks where no live lookup, prediction, or external enrichment is needed.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Missing required fields (row_id, date, company_group) — validation error returned
- Date field not in YYYY-MM-DD format — schema validation failure
- Numeric values outside allowed range (±1,000,000,000,000) — schema rejection
- Empty rows array — minimum 1 item required
- Invalid field enum value — must be registered_entities or changed_entities

## How this service works

Registry snapshots — String normalisation + IQR outlier flags: String normalisation + IQR outlier flags 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: one covering string normalisation of the supplied registry snapshot records and one flagging rows whose numeric values fall outside the IQR bounds for the selected field (registered_entities or changed_entities), based entirely on the supplied data with no live lookups or external calls.
