# Call Centre Equal-Width Histogram

> Call Centre 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 2026-10-24).

Computes an equal-width histogram over call centre records (calls or wait_seconds) with a configurable number of bins, using local numeric processing only.

## 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 call-centre-equal-width-histogram-bb5446c0 -d '<json body>'
```

Example prompt: Can you compute a 10-bin equal-width histogram over the wait_seconds field for these call centre records: row-1 team-a 2026-10-01 calls=50 wait=120, row-2 team-b 2026-10-02 calls=80 wait=340, row-3 team-a 2026-10-03 calls=30 wait=95?

## When to prefer this

Choose this endpoint when you need a fast, local equal-width frequency histogram over call centre metrics (calls or wait_seconds) with no external dependencies or enrichment. Ideal for up to 200 records when you want binned distribution output at low cost ($0.01 USDC). Prefer this over general-purpose analytics when the domain is specifically call centre data with the defined schema (team, date, calls, wait_seconds).

## Known failure modes

- More than 200 rows submitted — request rejected due to maxItems constraint
- Invalid date format (non-YYYY-MM-DD) causes schema validation failure
- Bins parameter outside 1–30 range returns validation error
- Field value not in enum ['calls','wait_seconds'] causes rejection
- Empty rows array rejected (minItems:1)
- Null numeric values in calls or wait_seconds may affect bin computation
- row_id missing or empty string causes required field validation failure

## How this service works

Call centre - Equal-width histogram: Equal-width histogram for Call centre. 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 deliverable: bin edges (lower and upper boundaries for each equal-width interval) and the count of records falling into each bin, computed locally from the submitted call centre rows for the chosen field (calls or wait_seconds).
