> Membership Activity Keyed Dataset Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Compares two keyed datasets of membership activity records (members and renewals by tier and date) and returns row-level differences and data-quality metrics.

## 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-keyed-dataset-comparison-9c69fad4 -d '<json body>'
```

Example prompt: Compare these two membership activity datasets for me — the first has rows for group-a and group-b from October 2026 with member and renewal counts, and the second is a slightly updated version of the same rows; show me what changed between them.

## When to prefer this

Choose this endpoint when you have two structured membership datasets keyed by row_id and need a local, fast, numeric comparison of member counts and renewal figures across tiers and dates — with no external enrichment. Ideal for auditing data pipeline outputs, validating ETL corrections, or detecting drift between membership reporting snapshots. Prefer alternatives if you need forecasting, external data enrichment, or comparison of more than 200 rows.

## Known failure modes

- Missing required fields (row_id, tier, date, members, renewals) causes validation error
- Date strings not matching YYYY-MM-DD pattern are rejected
- Exceeding 200 rows in either dataset returns an error
- Empty rows array (minItems:1 violated) causes rejection
- Numeric values outside the allowed range trigger validation failure

## How this service works

Membership activity - Keyed dataset comparison: Keyed dataset comparison 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 keyed dataset comparison deliverable.

## Output

Returns a bounded keyed dataset comparison deliverable: a structured result showing row-by-row differences between the two supplied membership datasets, including numeric deltas for members and renewals fields, matched/unmatched row indicators, and local data-quality assessments. No external data is fetched or appended.
