# Validator Uptime — Numeric Row Ordering + Adjacent Row Changes

> Validator Uptime — Numeric Row Ordering + Adjacent Row Changes is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-26).

Analyzes validator uptime records by sorting rows numerically and computing adjacent row changes for online_minutes or observed_minutes across up to 200 rows.

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 validator-uptime-numeric-row-ordering-adjacent-row-changes-49a43ab8 -d '<json body>'
```

Example prompt: I have validator uptime records with online_minutes and observed_minutes for each day — can you sort them numerically by online_minutes and show me what changed between consecutive rows? I have 4 rows: 2026-10-01 group-a 10/1, 2026-10-02 group-b 20/2, 2026-10-03 group-a 15/3, 2026-10-04 group-b 30/4.

## When to prefer this

Use this endpoint when you have a batch of validator uptime records (up to 200 rows) and need both a numerically sorted view and adjacent row change analysis in a single call at very low cost ($0.01 USDC for both reports). Ideal for blockchain/staking infrastructure monitoring workflows where you want offline, reproducible analytics without live data dependencies.

## Known failure modes

- More than 200 rows submitted — request rejected or truncated
- Missing required fields (row_id, date, online_minutes, observed_minutes) — validation error
- Invalid date format not matching YYYY-MM-DD pattern — schema rejection
- Null values in numeric fields may affect delta computation
- field enum value not one of online_minutes or observed_minutes — error

## How this service works

Validator uptime — Numeric row ordering + Adjacent row changes: Numeric row ordering + Adjacent row changes for supplied validator uptime records (online_minutes, observed_minutes). 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 input rows reordered by the selected numeric field (online_minutes or observed_minutes), and (2) adjacent row change values showing the delta between each consecutive row pair — all computed locally without any live data lookup or external calls.
