# Redirect Observations — Numeric Row Ordering + Two-Measure Correlation

> Redirect Observations — Numeric Row Ordering + 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 2026-11-02).

Analyzes redirect observation records by computing numeric row ordering and two-measure correlation (redirect_count vs final_status_code) for up to 200 rows, returning two independent analytical reports.

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 redirect-observations-numeric-row-ordering-two-measure-correlation-f61a1e19 -d '<json body>'
```

Example prompt: I have 150 rows of redirect observation data with redirect_count and final_status_code fields — can you run numeric row ordering and a two-measure correlation analysis on them, using redirect_count as the primary field?

## When to prefer this

Choose this endpoint when you have tabular redirect observation records (up to 200 rows) and need both a numeric row ranking and a statistical correlation between redirect_count and final_status_code in a single low-cost call ($0.01 USDC). Prefer this over general-purpose analytics tools when your data specifically involves web redirect metrics and you want two bundled reports without setting up your own statistical environment.

## Known failure modes

- More than 200 rows submitted — exceeds maximum row limit
- Missing required fields (row_id, redirect_count, final_status_code) — validation error
- Invalid date format not matching YYYY-MM-DD pattern
- Null values in both measure fields preventing correlation computation
- Payment not completed — x402 payment required before processing

## How this service works

Redirect observations — Numeric row ordering + Two-measure correlation: Numeric row ordering + Two-measure correlation for supplied redirect observations records (redirect_count, final_status_code). 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 independent analytical reports: (1) a numeric row ordering report ranking the supplied redirect observation records, and (2) a two-measure correlation report quantifying the statistical relationship between redirect_count and final_status_code across the submitted rows.
