# Customer Segment Observations — Adjacent Row Changes + Two-Measure Correlation

> Customer Segment Observations — Adjacent Row Changes + Two-Measure Correlation is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Analyzes customer segment observation rows to produce two local analytical reports: adjacent row change detection and two-measure correlation between account_count and revenue_amount.

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 customer-segment-observations-adjacent-row-changes-two-measure-5c1baede -d '<json body>'
```

Example prompt: Can you run adjacent row change detection and two-measure correlation on my customer segment data — I have rows with account_count and revenue_amount grouped by company_group across dates in October 2026, up to about 50 rows — and give me both reports?

## When to prefer this

Choose this endpoint when you have up to 200 customer segment observation records with account_count and revenue_amount fields and want both sequential row-change analysis and cross-measure correlation in a single low-cost call ($0.01 USDC). Prefer it over general statistics services when your data is already structured with row_id, date, and company_group fields and you need two bundled reports with no external data lookups or predictions.

## Known failure modes

- Input rows exceed 200 item limit — request will be rejected
- Missing required fields (row_id, date, company_group, account_count, or revenue_amount) cause validation errors
- Date values not matching YYYY-MM-DD pattern will fail schema validation
- Null values in both measure fields may degrade correlation computation
- Payment of 0.01 USDC not completed causes x402 payment-required error
- Fewer than 2 rows provided may produce degenerate or empty change reports

## How this service works

Customer segment observations — Adjacent row changes + Two-measure correlation: Adjacent row changes + Two-measure correlation 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

Two analytical reports generated locally from the supplied rows: (1) an adjacent row changes report showing differences between consecutive rows for the specified measure, and (2) a two-measure correlation report quantifying the statistical relationship between account_count and revenue_amount across up to 200 supplied rows.
