# Web Traffic Equal-Width Histogram

> Web Traffic Equal-Width Histogram is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-19).

Computes an equal-width histogram over web traffic session or conversion data, partitioning up to 200 records into user-specified bins for distribution analysis.

## 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 web-traffic-equal-width-histogram-3dfec71b -d '<json body>'
```

Example prompt: Can you build an equal-width histogram for my web traffic sessions data? I have 4 rows — channel group-a on 2026-10-01 with 10 sessions, group-b on 2026-10-02 with 20 sessions, group-a on 2026-10-03 with 15 sessions, and group-b on 2026-10-04 with 30 sessions — and I want 5 bins on the sessions field.

## When to prefer this

Choose this endpoint when you need a fast, local, no-external-dependency distribution analysis of web traffic session or conversion counts — especially when you already have structured tabular records with channels and dates and want a numeric frequency histogram without sending data to an external analytics platform. Best for datasets up to 200 rows where you want equal-width binning (not quantile/equal-frequency).

## Known failure modes

- More than 200 rows submitted — request rejected
- Invalid date format (must be YYYY-MM-DD) causes row rejection
- Bins value outside 1–30 range returns validation error
- Missing required fields (row_id, channel, date, sessions, conversions) causes schema error
- All values null for selected field results in empty or degenerate histogram
- Non-numeric values in sessions/conversions fields fail type validation

## How this service works

Web traffic - Equal-width histogram: Equal-width histogram for Web traffic. Up to 200 supplied typed records. Local numeric and data-quality processing; no external enrichment or forecasting. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded equal-width histogram deliverable.

## Output

Returns a bounded equal-width histogram: bin boundaries, counts per bin, and frequency distribution metadata for the selected numeric field (sessions or conversions) across the supplied web traffic rows.
