# Source Attribution Analytics: Equal-Width Histogram + Keyed Dataset Comparison

> Source Attribution Analytics: Equal-Width Histogram + 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 2026-10-22).

Runs two local analytical reports on source attribution records — an equal-width histogram and a keyed dataset comparison — for up to 200 rows of cited_sources and verified_links data.

## 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-attribution-analytics-equal-width-histogram-keyed-dataset-f31da55b -d '<json body>'
```

Example prompt: I have two batches of source attribution records (up to 200 rows each) with cited_sources and verified_links fields — can you generate an equal-width histogram with 10 bins on the cited_sources field and also run a keyed dataset comparison between the two batches?

## When to prefer this

Choose this endpoint when you need two simultaneous analytical reports — a distribution histogram and a keyed row-level comparison — on source attribution data (cited_sources, verified_links) without requiring live lookups, external enrichment, or predictions. Ideal for journalism, media auditing, or content verification workflows where you have two datasets to compare and want statistical distribution insight in a single low-cost call.

## Known failure modes

- More than 200 rows submitted — request rejected with validation error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- bins value exceeds 30 or is less than 1 — rejected by schema
- Missing required fields (row_id, channel_group, date, cited_sources, verified_links) — validation error
- Null values in numeric fields may affect histogram bin computation
- Mismatched row_ids between rows and other datasets may reduce comparison coverage

## How this service works

Source attribution — Equal-width histogram + Keyed dataset comparison: Equal-width histogram + Keyed dataset comparison for supplied source attribution records (cited_sources, verified_links). 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

Returns two analytical reports: (1) an equal-width histogram partitioning the chosen field (cited_sources or verified_links) into the specified number of bins with frequency counts and bin boundaries, and (2) a keyed dataset comparison highlighting differences between the primary and secondary datasets matched by row_id. All computation is performed locally with no external lookups or predictions.
