# Call Centre Adjacent Row Changes

> Call Centre Adjacent Row Changes is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Computes period-over-period adjacent row changes for call centre metrics (calls or wait_seconds) across up to 200 input records

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 call-centre-adjacent-row-changes-aa229d64 -d '<json body>'
```

Example prompt: Can you calculate the adjacent row changes for calls across these 4 records — team group-a on 2026-10-01 had 10 calls, group-b on 2026-10-02 had 20 calls, group-a on 2026-10-03 had 15 calls, and group-b on 2026-10-04 had 30 calls — using the calls field?

## When to prefer this

Choose this endpoint when you need fast, local period-over-period difference calculations on call centre row data (calls or wait_seconds) without any external API dependency or forecasting. Ideal for sequential time-series analysis of call volume or wait time across up to 200 records where you already have the data and just need the adjacent deltas computed.

## Known failure modes

- Fewer than 1 row supplied returns validation error
- More than 200 rows supplied exceeds maxItems limit
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- Missing required fields (row_id, team, date, calls, wait_seconds) causes rejection
- Field value not in enum ['calls','wait_seconds'] causes error
- Null numeric values may produce null deltas in output

## How this service works

Call centre - Adjacent row changes: Adjacent row changes 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 adjacent row changes deliverable.

## Output

Returns computed adjacent row change values for each input record, showing the numeric difference between each row and its preceding row for the specified field (calls or wait_seconds), based purely on local numeric processing of the supplied data with no external enrichment
