# Registry Snapshots Base-100 Series and IQR Outlier Flags

> Registry Snapshots Base-100 Series and 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).

Computes Base-100 indexed time series and IQR-based outlier flags for registry snapshot data (registered_entities, changed_entities) across up to 200 rows in two independent 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 registry-snapshots-base-100-series-and-iqr-outlier-flags-e4f9cda1 -d '<json body>'
```

Example prompt: Take these 4 rows of registry snapshot data and give me a Base-100 series plus IQR outlier flags for the registered_entities field, anchoring the index at row 0: [{"row_id":"row-1","company_group":"group-a","date":"2026-10-01","registered_entities":10,"changed_entities":1},{"row_id":"row-2","company_group":"group-b","date":"2026-10-02","registered_entities":20,"changed_entities":2},{"row_id":"row-3","company_group":"group-a","date":"2026-10-03","registered_entities":15,"changed_entities":3},{"row_id":"row-4","company_group":"group-b","date":"2026-10-04","registered_entities":30,"changed_entities":4}].

## When to prefer this

Choose this endpoint when you have already collected registry snapshot data (registered_entities or changed_entities counts by company group and date) and need fast, offline statistical analysis — specifically Base-100 normalization and IQR outlier detection — without requiring live data lookup, external enrichment, or predictive modeling. It is ideal when you want two analytical reports (one for each metric) in a single cheap call ($0.01 USDC) on up to 200 rows.

## Known failure modes

- Missing required fields (row_id, company_group, date, registered_entities, changed_entities) causes validation error
- Exceeding 200 rows returns an error or truncation
- Invalid date format (not YYYY-MM-DD) causes schema rejection
- base_index referencing a row index beyond the array length causes computation failure
- Null values in the chosen field may affect IQR and base-100 calculations
- Payment failure (insufficient USDC) blocks the request entirely

## How this service works

Registry snapshots — Base-100 series + IQR outlier flags: Base-100 series + 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

Returns two independent analytical reports: (1) a Base-100 indexed time series normalizing the selected field relative to the specified base row, and (2) IQR-based outlier flags identifying rows whose values fall outside the interquartile range. Both reports cover the same supplied rows (up to 200) and are computed locally without external data lookups.
