## 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 membership-activity-daily-sum-series-2940de5d -d '<json body>'
```

Example prompt: Take these membership records for tiers group-a and group-b across October 2026 and compute the daily sum series for the members field — I have 4 rows with row IDs row-1 through row-4, dates from 2026-10-01 to 2026-10-04, and member counts of 10, 20, 15, and 30 respectively.

## When to prefer this

Choose this endpoint when you need to aggregate raw membership activity records (members or renewals) into a clean daily sum time series, grouped by date across up to 200 typed rows. It is ideal for subscription analytics, membership dashboards, and retention reporting where local computation without external enrichment is sufficient and cost-efficiency matters.

## Known failure modes

- Input array exceeds 200 rows — request rejected with validation error
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- Missing required fields (row_id, tier, date, members, renewals) causes item-level rejection
- Invalid field enum value (not 'members' or 'renewals') returns validation error
- Empty rows array (minItems: 1 violated) causes request failure
- Numeric values outside allowed range (-1e12 to 1e12) rejected
