# Translation Delivery — Trailing Mean Series + Equal-Width Histogram

> Translation Delivery — 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 2026-10-26).

Computes a trailing moving average time series and an equal-width frequency histogram for translation delivery records (translated_words or source_words) across up to 200 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 translation-delivery-trailing-mean-series-equal-width-histogram-67c97f02 -d '<json body>'
```

Example prompt: Run a trailing mean series with a window of 5 and an equal-width histogram with 10 bins on the translated_words field for these translation delivery records: [row-1, 2024-01-01, group-a, translated_words=500, source_words=450], [row-2, 2024-01-02, group-a, translated_words=620, source_words=580], ...

## When to prefer this

Choose this endpoint when you have translation delivery data (translated_words, source_words) and need both a time-smoothed trend view (trailing mean) and a distribution view (histogram) in a single low-cost call. Ideal for localization teams tracking output velocity or auditing volume distributions without setting up a local analytics pipeline. Not suitable if you need forecasting, external data enrichment, or more than 200 rows.

## Known failure modes

- Fewer rows than window size — trailing mean cannot be computed for early rows
- Invalid date format (not YYYY-MM-DD) causes row rejection
- More than 200 rows supplied — request rejected or truncated
- bins parameter out of range (< 1 or > 30) returns validation error
- All values null for selected field — histogram and mean series cannot be computed
- Missing required fields (row_id, date) causes row-level errors

## How this service works

Translation delivery — Trailing mean series + Equal-width histogram: Trailing mean series + Equal-width histogram for supplied translation delivery records (translated_words, source_words). 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 analytical reports: (1) a trailing mean series showing the rolling average of the chosen field (translated_words or source_words) over the specified window size, indexed by date/row order; and (2) an equal-width histogram dividing the field's value range into the specified number of bins with frequency counts per bin. Both reports are computed locally from the supplied data with no external lookups.
