# Session Conversion Rate Distribution Histogram

> Session Conversion Rate Distribution Histogram is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-16).

Generates a distribution histogram of session conversion rates from supplied retail session data, grouped into configurable bins.

## 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 session-conversion-rate-distribution-histogram-3c6d452f -d '<json body>'
```

Example prompt: Can you generate a distribution histogram with 10 bins for my session conversion data? Here are my rows: 1000 sessions with 30 converted, 1100 sessions with 45 converted, 950 sessions with 28 converted, and 1200 sessions with 60 converted.

## When to prefer this

Choose this endpoint when you have a list of retail session and conversion counts and want to understand the statistical distribution of conversion rates across those observations — particularly useful for spotting outliers, clusters, or skew in conversion performance. Prefer this over a simple mean or summary statistic when you need to see the shape of the data. Use when working with local scenario analysis without needing live inventory, platform fees, or order execution.

## Known failure modes

- Fewer than 2 rows provided — minimum 2 data points required
- More than 200 rows submitted — maximum row limit exceeded
- sessions value of 0 — exclusive minimum violated, division by zero risk
- bins value outside 1–30 range — validation error
- converted_sessions exceeding sessions value — may produce rates above 100%, handled locally but may skew histogram
- Malformed row objects missing required sessions or converted_sessions fields

## How this service works

Session conversion rate - Distribution histogram: Distribution histogram for Session conversion rate. Supplied retail figures only. Local calculation and scenario analysis; no live inventory, account access, platform fee lookup or order execution. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded distribution histogram deliverable.

## Output

A bounded distribution histogram showing how session conversion rates (converted_sessions / sessions) are spread across the specified number of bins, with each bin covering a range of conversion rate values and indicating how many input rows fall within that range.
