# Product Feature Telemetry – Base-100 Index Series

> Product Feature Telemetry – Base-100 Index Series is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Computes a base-100 index series from product feature telemetry rows, normalizing events or unique-user counts relative to a chosen baseline row for local descriptive analytics.

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-base-100-index-series-c578868c -d '<json body>'
```

Example prompt: Can you run a base-100 index on my feature telemetry data — I have daily event counts for features 'checkout-v2' and 'dashboard' from Oct 1 to Oct 7, and I want to index everything against the first row using the 'events' field?

## When to prefer this

Choose this endpoint when you have up to 200 typed product feature telemetry records and need a relative, base-100 indexed view of event counts or unique-user counts over time — without any forecasting, enrichment, or external data. Ideal for descriptive trend comparison across features where absolute numbers differ greatly and a normalized scale is needed for fair comparison.

## Known failure modes

- Fewer than 1 row supplied — rejected by minItems validation
- base_index references a row position outside the supplied array — rejected by maximum constraint
- Date strings not matching YYYY-MM-DD pattern — schema validation error
- More than 200 rows supplied — rejected by maxItems limit
- Invalid field enum value (not 'events' or 'unique_users') — schema error
- Null metric values at the base index row may produce undefined or divide-by-zero results

## How this service works

Product feature telemetry - Base-100 series: Base-100 series 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 base-100 series report.

## Output

Returns a bounded base-100 index series report for up to 200 typed telemetry rows. Each row's selected metric (events or unique_users) is normalized relative to the designated base index row, yielding indexed values that express change relative to 100 at the baseline. The output is a local descriptive analytics result with no enrichment, forecasting, or external data.
