# Business Registrations Trailing Mean & Base-100 Series Analyzer

> Business Registrations Trailing Mean & Base-100 Series Analyzer 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).

Computes trailing moving-average and base-100 index series for business registration and closure data supplied by the caller, returning two analytical reports per call.

## 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 business-registrations-trailing-mean-base-100-series-analyzer-cbe906c8 -d '<json body>'
```

Example prompt: I have monthly new_registrations and closures data for two regions across 12 rows — can you run a trailing mean with a window of 3 and a base-100 index anchored at row 0 on the new_registrations field?

## When to prefer this

Choose this endpoint when you have your own business registration or closure data and need both a smoothed rolling-average trend and a normalized base-100 index series computed together in a single low-cost call. Ideal for economic analysts, policy researchers, or dashboard builders who want offline-style statistical transformation without writing custom code. Prefer this over generic statistics APIs when working specifically with new_registrations and closures fields in a multi-region, time-series context and want both report types for $0.01.

## Known failure modes

- Fewer than 2 rows supplied — minimum row count not met
- window parameter exceeds number of rows — rolling mean cannot be computed
- base_index out of range for the supplied row count
- null values in the selected field may produce gaps or NaN in output series
- More than 200 rows submitted — exceeds maximum row limit
- Missing required row fields (row_id, region, date, new_registrations, closures) cause validation errors
- Invalid date format (not YYYY-MM-DD) causes schema rejection

## How this service works

Business registrations — Trailing mean series + Base-100 series: Trailing mean series + Base-100 series for supplied business registrations records (new_registrations, closures). 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 trailing mean series — each row's value replaced by the rolling average over the specified window — and (2) a base-100 index series — each row's value expressed as an index relative to the chosen base row, both computed on either the new_registrations or closures field across all supplied rows grouped by region.
