## 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 equipment-runtime-adjacent-row-changes-732ddb6a -d '<json body>'
```

Example prompt: Calculate the adjacent row changes in run_hours for these machine records — I have 4 entries for group-a and group-b across Oct 1–4, 2026, and I want to see how the runtime shifted between each consecutive row.

## When to prefer this

Choose this endpoint when you have sequential equipment runtime or downtime records and need fast, local period-over-period delta calculations without requiring external enrichment or forecasting. It is ideal for batch sizes up to 200 rows, costs $0.01 USDC per call, and handles numeric quality processing in-process. Prefer it over general analytics services when your data is already structured as dated machine records and you simply need adjacent-row difference values.

## Known failure modes

- Fewer than 1 row supplied returns a validation error
- More than 200 rows exceeds the maxItems limit and is rejected
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- Unknown field value outside the enum [run_hours, downtime_hours] is rejected
- Null numeric values in the selected field may produce null deltas in output
- Missing required fields (row_id, machine, date) cause record-level rejection

## How this service works

Equipment runtime - Adjacent row changes: Adjacent row changes for Equipment runtime. 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 the selected field (run_hours or downtime_hours) across the supplied machine records, showing the numeric delta between each consecutive row ordered by date and machine grouping.
