## 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-category-frequencies-1a8566eb -d '<json body>'
```

Example prompt: Can you compute the category frequencies for this membership activity dataset? I have 4 rows: row-1 on 2026-10-01 tier group-a with 10 members and 1 renewal, row-2 on 2026-10-02 tier group-b with 20 members and 2 renewals, row-3 on 2026-10-03 tier group-a with 15 members and 3 renewals, and row-4 on 2026-10-04 tier group-b with 30 members and 4 renewals.

## When to prefer this

Choose this endpoint when you need a quick, cheap ($0.01 USDC) frequency/distribution count of membership tier categories from a small dataset (up to 200 records) and want purely local numeric processing with no external API calls or enrichment. Ideal for lightweight reporting tasks where you already have structured membership activity records and just need category aggregation.

## Known failure modes

- Empty or missing rows array returns validation error
- Row count exceeding 200 items rejected with maxItems error
- Missing required fields (row_id, tier, date, members, renewals) cause schema validation failure
- Invalid date format (non-YYYY-MM-DD) triggers pattern mismatch error
- Null or out-of-range numeric values for members or renewals may be rejected

## How this service works

Membership activity - Category frequencies: Category frequencies for Membership activity. 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 category frequencies deliverable.

## Output

A bounded category frequencies deliverable containing the count (and potentially proportion) of records falling into each distinct tier/category found in the submitted membership activity rows, computed locally without external enrichment.
