# Redirect Observations — Adjacent Row Changes + Secondary-Measure Weighted Mean

> Redirect Observations — Adjacent Row Changes + 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 adjacent-row delta changes and a secondary-measure weighted mean for up to 200 redirect observation records containing redirect_count and final_status_code fields.

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-adjacent-row-changes-secondary-measure-weighted-c243befd -d '<json body>'
```

Example prompt: I have 4 rows of redirect observation data — row-1 for group-a on 2026-10-01 with redirect_count 10 and final_status_code 1, row-2 for group-b on 2026-10-02 with redirect_count 20 and final_status_code 2, and so on — can you run the adjacent row changes and weighted mean reports on the redirect_count field for me?

## When to prefer this

Choose this endpoint when you have structured redirect observation records with redirect_count and final_status_code and need both sequential row-to-row delta analysis and a weighted mean summary in a single low-cost call. Ideal for lightweight batch statistical analysis of web redirect logs without needing a full analytics platform or live data lookup.

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Missing required fields (row_id, date, redirect_count, final_status_code) on any row — validation error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Null values in numeric fields may affect weighted mean calculation
- Invalid field enum value (not 'redirect_count' or 'final_status_code') — rejected

## How this service works

Redirect observations — Adjacent row changes + Secondary-measure weighted mean: Adjacent row changes + Secondary-measure weighted mean 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 statistical reports: (1) adjacent row changes showing the delta between consecutive redirect_count or final_status_code values across rows, and (2) a weighted mean of the chosen secondary measure, both computed locally on the supplied data with no external lookups. Supports up to 200 input rows.
