# Data Freshness Trailing Mean Series + Base-100 Series

> Data Freshness Trailing Mean Series + Base-100 Series is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Computes trailing mean series and base-100 indexed series for user-supplied data freshness records (age_minutes and record_count fields), returning two independent analytical reports in a single call.

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 data-freshness-trailing-mean-series-base-100-series-bf6fbfbf -d '<json body>'
```

Example prompt: Analyze my data freshness records — I have about 50 rows with date, age_minutes, and record_count — and give me both a trailing mean series using a window of 5 and a base-100 series anchored at index 0 for the age_minutes field.

## When to prefer this

Choose this endpoint when you have tabular data freshness records with date, age_minutes, and record_count columns and need both a rolling average time series and a base-100 normalized index in a single low-cost call. It is ideal for monitoring pipelines, data quality dashboards, or operational reporting where you want smoothed trends and relative change without external lookups or predictions.

## Known failure modes

- Fewer than 1 row supplied — minimum 1 row required
- More than 200 rows supplied — exceeds maxItems limit
- Invalid date format — must match YYYY-MM-DD pattern
- Window size less than 2 or greater than 200 — out of allowed range
- Base index out of range — must be between 0 and 199 and within the number of rows supplied
- Field value not 'age_minutes' or 'record_count' — only these two enums are accepted
- Payment not attached or insufficient — requires 0.01 USDC via x402

## How this service works

Data freshness — Trailing mean series + Base-100 series: Trailing mean series + Base-100 series for supplied data freshness records (age_minutes, record_count). 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 showing the rolling average of the selected field (age_minutes or record_count) over the specified window size, and (2) a base-100 indexed series normalizing values relative to the row at the specified base index. Results cover up to 200 input rows.
