## 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

Example prompt: Can you give me a grouped numeric summary of these time entries — group them by project and summarize the hours field? I have up to 4 rows: row-1 on 2026-10-01 project group-a 10 hours 1 billable, row-2 on 2026-10-02 project group-b 20 hours 2 billable, row-3 on 2026-10-03 project group-a 15 hours 3 billable, row-4 on 2026-10-04 project group-b 30 hours 4 billable.

## When to prefer this

Use this endpoint when you have up to 200 time entry records and need a fast, local grouped numeric summary by project without external data enrichment. Ideal for billing, payroll prep, or sprint analytics where you already hold the raw time log data and simply need aggregated group-level statistics on hours or billable_hours.

## Known failure modes

- Missing required fields (row_id, project, date, hours, billable_hours) returns validation error
- Submitting more than 200 rows exceeds maxItems and is rejected
- Invalid date format (not YYYY-MM-DD) fails pattern validation
- Null numeric values may affect aggregate calculations
- Empty rows array (minItems:1 violated) returns error
- Invalid field enum value (not 'hours' or 'billable_hours') rejected
