# Customer Segment Observations — Secondary-Measure Weighted Mean + Keyed Dataset Comparison

> Customer Segment Observations — Secondary-Measure Weighted Mean + Keyed Dataset Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-25).

Computes a secondary-measure weighted mean and performs a keyed dataset comparison on up to 200 customer segment observation rows (account_count, revenue_amount), returning two analytical reports.

## 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 customer-segment-observations-secondary-measure-weighted-mean-keyed-cdc69242 -d '<json body>'
```

Example prompt: I have two sets of customer segment records — rows of company_group, date, account_count, and revenue_amount — and I want to compute the weighted mean of revenue_amount (weighted by account_count) across segments, plus a keyed comparison between the two datasets. Can you run both reports on my data?

## When to prefer this

Choose this endpoint when you have up to 200 customer segment observation rows with account_count and revenue_amount fields and need both a weighted mean computation (using one measure to weight the other) and a keyed comparison between two datasets in a single low-cost call. It is ideal for period-over-period segment analysis, data validation between two snapshots, or computing weighted aggregates across company groups without needing a full data warehouse.

## Known failure modes

- Supplying more than 200 rows results in rejection or truncation
- Rows missing required fields (row_id, company_group, date, account_count, revenue_amount) will cause validation errors
- Null values in the weight or target field may affect weighted mean accuracy or cause errors
- Date strings not matching YYYY-MM-DD pattern will fail schema validation
- Empty rows array (minItems: 1 violated) will return an error
- Mismatched keys between primary and comparison datasets may yield empty or partial comparison results

## How this service works

Customer segment observations — Secondary-measure weighted mean + Keyed dataset comparison: Secondary-measure weighted mean + Keyed dataset comparison for supplied customer segment observations records (account_count, revenue_amount). 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) the secondary-measure weighted mean computed across the supplied rows for the chosen field (account_count or revenue_amount), and (2) a keyed dataset comparison between the primary rows and the comparison dataset, highlighting differences by key (row_id, company_group, date). All computation is local with no external lookups.
