# Travel Administration — Two-Measure Correlation + Secondary-Measure Weighted Mean

> Travel Administration — 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 2026-10-29).

Computes Pearson correlation between trip_count and recorded_cost, plus a weighted mean of a selected secondary measure, across up to 200 travel administration records.

## 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 travel-administration-two-measure-correlation-secondary-measure-0a50a88c -d '<json body>'
```

Example prompt: Can you run a correlation analysis between trip_count and recorded_cost, plus compute the weighted mean of trip_count, for these travel records: team-a had 10 trips costing $500 on 2024-01-01, team-b had 20 trips costing $800 on 2024-01-02, and team-a had 15 trips costing $620 on 2024-01-03?

## When to prefer this

Choose this endpoint when you have up to 200 travel administration records with trip counts and costs and need both a correlation coefficient and a weighted mean in a single cheap ($0.01 USDC) call, with no need for live data, predictions, or external enrichment. It is ideal for lightweight, self-contained statistical reporting on local datasets where you want two distinct analytical outputs in one request.

## Known failure modes

- More than 200 rows submitted — request rejected or truncated
- Missing required fields (row_id, date, trip_count, recorded_cost) cause validation errors
- Null values in both measure columns may produce undefined correlation
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- Insufficient variance in one measure may yield correlation of NaN or undefined
- Invalid enum value for 'field' parameter causes rejection

## How this service works

Travel administration — Two-measure correlation + Secondary-measure weighted mean: Two-measure correlation + Secondary-measure weighted mean for supplied travel administration records (trip_count, recorded_cost). 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 Pearson correlation coefficient between the trip_count and recorded_cost columns across all supplied rows, and (2) a weighted mean for the selected secondary measure field (trip_count or recorded_cost). All computation is local with no external lookups or predictions.
