# Product Feature Telemetry — Keyed Dataset Comparison

> Product Feature Telemetry — Keyed Dataset Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-17).

Compares two keyed datasets of product feature telemetry records (up to 200 rows each) and returns local descriptive analytics on differences between them.

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 product-feature-telemetry-keyed-dataset-comparison-a73943d2 -d '<json body>'
```

Example prompt: Compare these two batches of feature telemetry data for me — the first dataset has events and unique_users for features like 'group-a' and 'group-b' across October 2026, and the second dataset has slightly different counts for the same rows — give me a keyed comparison report showing how they differ descriptively.

## When to prefer this

Choose this endpoint when you need a fast, local descriptive comparison between two structured product feature telemetry datasets keyed by row_id, feature, and date — without needing enrichment, forecasting, or external data. It is ideal for before/after release analysis, A/B group comparisons, or QA audits of parallel telemetry pipelines with up to 200 records per dataset.

## Known failure modes

- rows array empty or missing — minItems:1 required
- row objects missing required fields (row_id, feature, date, events, unique_users)
- date field not matching YYYY-MM-DD pattern
- more than 200 rows supplied to either dataset — maxItems:200 limit
- numeric fields outside allowed range (-1e12 to 1e12)
- payment not attached or insufficient — x402 protocol required at $0.01 USDC

## How this service works

Product feature telemetry - Keyed dataset comparison: Keyed dataset comparison for Product feature telemetry. Up to 200 supplied typed records. Local descriptive analytics; no enrichment or forecast. One of 25 new profiles across 20 shared operations in this industry. 0.01 USDC includes one bounded keyed dataset comparison report.

## Output

A bounded keyed dataset comparison report containing local descriptive analytics — such as per-feature and per-row difference summaries, count deltas, and statistical summaries — comparing the two supplied datasets. No enrichment or forecasting is included.
