# Endpoint Telemetry — Numeric Row Ordering + Secondary-Measure Weighted Mean

> Endpoint Telemetry — Numeric Row Ordering + 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 2026-11-02).

Ranks telemetry rows numerically by agent_count and computes a reporting_agents-weighted mean for endpoint telemetry datasets of up to 200 rows.

## 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 endpoint-telemetry-numeric-row-ordering-secondary-measure-weighted-mean-1928558f -d '<json body>'
```

Example prompt: Rank these telemetry rows by agent_count and compute the reporting_agents-weighted mean: row-1 on 2026-10-01 in group-a had agent_count=10 and reporting_agents=1, row-2 on 2026-10-02 in group-b had agent_count=20 and reporting_agents=2, row-3 on 2026-10-03 in group-a had agent_count=15 and reporting_agents=3.

## When to prefer this

Choose this endpoint when you have pre-collected endpoint telemetry rows with agent_count and reporting_agents fields and need both a numeric ranking and a weighted mean in a single call. It is ideal for lightweight, local analytical computation on up to 200 rows without requiring external data sources, live lookups, or predictions. Prefer it over general analytics tools when cost-efficiency matters ($0.01 for two reports) and your data is already structured to its schema.

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Missing required fields (row_id, control_group, date, agent_count, reporting_agents) on any row — validation error
- Invalid date format (must match YYYY-MM-DD pattern) — schema validation failure
- Numeric values outside allowed range (-1e12 to 1e12) — schema rejection
- All reporting_agents values are null — weighted mean cannot be computed
- Payment of 0.01 USDC not completed — 402 Payment Required response

## How this service works

Endpoint telemetry — Numeric row ordering + Secondary-measure weighted mean: Numeric row ordering + Secondary-measure weighted mean for supplied endpoint telemetry records (agent_count, reporting_agents). 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 for the supplied telemetry rows: (1) rows numerically ordered by the selected field (agent_count or reporting_agents), and (2) a weighted mean of the selected field using the secondary measure as weights. Both reports are computed locally with no external lookups or predictions, covering up to 200 input rows.
