# Source Diversity Keyed Dataset Comparison + Missing-Value Fill

> Source Diversity Keyed Dataset Comparison + Missing-Value Fill is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-24).

Compares two keyed source-diversity datasets (source_count, outlet_count) and fills missing values, producing 2 analytical reports for up to 200 rows.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 source-diversity-keyed-dataset-comparison-missing-value-fill-586b0741 -d '<json body>'
```

Example prompt: Compare these two source diversity datasets for me — the first has source_count and outlet_count by channel_group and date, and the second is the updated version. I want to see where the values differ and have any missing source_count values filled in. Both datasets have up to 50 rows each.

## When to prefer this

Choose this endpoint when you have two structured source-diversity datasets keyed by row_id/channel_group/date and need a side-by-side comparison plus missing-value fill for source_count or outlet_count, up to 200 rows, at very low cost. It is ideal for media analytics pipelines that need offline, deterministic reconciliation of two reporting snapshots without external data access.

## Known failure modes

- Missing required fields (row_id, channel_group, date, source_count, outlet_count) cause validation errors
- Exceeding 200 rows per dataset returns an error
- Invalid date format (non YYYY-MM-DD) causes rejection
- field enum value not one of 'source_count' or 'outlet_count' causes schema error
- Payment of 0.01 USDC not completed triggers 402 response

## How this service works

Source diversity — Keyed dataset comparison + Explicit missing-value fill: Keyed dataset comparison + Explicit missing-value fill for supplied source diversity records (source_count, outlet_count). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.

## Output

Two analytical reports covering: (1) a keyed comparison highlighting differences between the two supplied datasets for the selected field (source_count or outlet_count), and (2) explicit fill results for missing values in those rows — all computed locally without external lookups.
