# Translation Delivery Analytics — Two-Measure Correlation + Secondary-Measure Weighted Mean

> Translation Delivery Analytics — Two-Measure Correlation + Secondary-Measure Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Computes two statistical reports on translation delivery data: a Pearson/rank correlation between translated_words and source_words, plus a weighted mean of a chosen secondary measure, for up to 200 supplied rows.

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 translation-delivery-analytics-two-measure-correlation-secondary-0b547309 -d '<json body>'
```

Example prompt: Can you run a correlation between translated_words and source_words, plus a weighted mean of translated_words, on these 4 translation records: row-1 (group-a, 2026-10-01, source=1, translated=10), row-2 (group-b, 2026-10-02, source=2, translated=20), row-3 (group-a, 2026-10-03, source=3, translated=15), row-4 (group-b, 2026-10-04, source=4, translated=30)?

## When to prefer this

Choose this endpoint when you have raw translation delivery records (translated_words + source_words per row) and need both a correlation coefficient between the two measures and a weighted mean of one measure in a single low-cost call. It is ideal for small-to-medium datasets (up to 200 rows) where you want offline, reproducible statistical summaries without any external lookup or ML inference. Prefer alternatives if you need more than two reports, datasets larger than 200 rows, or real-time predictions.

## Known failure modes

- Fewer than 1 row supplied — returns validation error
- More than 200 rows supplied — rejected, maxItems exceeded
- Missing required fields (row_id, date, translated_words, source_words) — schema validation failure
- Invalid date format (not YYYY-MM-DD) — pattern mismatch error
- Numeric values outside allowed range (±1e12) — rejected
- Insufficient variance in data for meaningful correlation (e.g. all identical values) — may return null or NaN correlation

## How this service works

Translation delivery — Two-measure correlation + Secondary-measure weighted mean: Two-measure correlation + Secondary-measure weighted mean 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 computed locally on the supplied data: (1) a correlation statistic between translated_words and source_words across all provided rows, and (2) a weighted mean of the specified field (translated_words or source_words). No external data sources or predictions are involved.
