# Export Validation — Trailing Mean Series + Equal-Width Histogram

> Export Validation — Trailing Mean Series + Equal-Width Histogram is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-19).

Computes a trailing mean time series and an equal-width histogram for export validation data (valid_rows and exported_rows) over up to 200 supplied rows.

## 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 export-validation-trailing-mean-series-equal-width-histogram-983ef801 -d '<json body>'
```

Example prompt: Can you analyze my export validation data — I have 50 rows with valid_rows and exported_rows counts across several dataset groups — and produce a trailing mean series using a window of 5 for the valid_rows field, plus an equal-width histogram with 10 bins?

## When to prefer this

Choose this endpoint when you need both a rolling/trailing mean time series and a frequency histogram for export validation metrics (valid_rows or exported_rows) in a single low-cost call. It is ideal for lightweight, offline statistical summarization of up to 200 export pipeline records without requiring external data sources, prediction models, or professional assessment. Prefer it over general analytics platforms when you want a simple, deterministic, supply-your-own-data computation for pipeline health checks or data quality audits.

## Known failure modes

- Fewer than 1 row supplied — request rejected (minItems:1)
- More than 200 rows supplied — request rejected (maxItems:200)
- Invalid date format (not YYYY-MM-DD) — validation error
- Window size less than 2 or greater than 200 — validation error
- Bin count less than 1 or greater than 30 — validation error
- Null values in valid_rows or exported_rows — may produce incomplete series segments
- Missing required fields (row_id, dataset_group, date) — request rejected

## How this service works

Export validation — Trailing mean series + Equal-width histogram: Trailing mean series + Equal-width histogram for supplied export validation records (valid_rows, exported_rows). 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 statistical reports: (1) a trailing mean series showing the rolling average of the selected field (valid_rows or exported_rows) over the specified window size across the date-ordered rows, and (2) an equal-width histogram showing the frequency distribution of the selected field divided into the specified number of bins. Both reports are computed locally from the supplied data with no external lookups.
