# Source Diversity Base-100 Series + Equal-Width Histogram Analyzer

> Source Diversity Base-100 Series + Equal-Width Histogram Analyzer is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-23).

Generates a Base-100 indexed time series and an equal-width histogram for source_count or outlet_count fields in supplied source diversity data (up to 200 rows).

## 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-base-100-series-equal-width-histogram-analyzer-d2dc70e6 -d '<json body>'
```

Example prompt: Take my source diversity dataset of 150 rows with source_count and outlet_count fields, index the source_count values to base-100 starting from row 0, and generate an equal-width histogram with 8 bins — the channel groups are labeled 'print', 'digital', and 'broadcast' with dates from 2025-01-01 onward.

## When to prefer this

Choose this endpoint when you have pre-collected source diversity records (source_count, outlet_count) and need both a base-100 normalized trend series and a distribution histogram computed analytically from your own data — no live data fetching, prediction, or external enrichment is involved. Ideal for media analysts and journalism researchers who want two statistical views (trend + distribution) in a single low-cost call ($0.01 USDC) on datasets up to 200 rows.

## Known failure modes

- Rows exceeding 200 items will be rejected (maxItems constraint)
- Missing required fields (row_id, channel_group, date, source_count, outlet_count) will cause validation errors
- Invalid date format (not YYYY-MM-DD) will fail pattern validation
- base_index out of range (must be 0–199 and within row count) may produce unexpected indexing
- bins value outside 1–30 range will be rejected
- Null numeric values in the selected field may affect histogram bucketing or series calculation

## How this service works

Source diversity — Base-100 series + Equal-width histogram: Base-100 series + Equal-width histogram 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

Returns two analytical reports: (1) a Base-100 indexed time series normalizing the selected field (source_count or outlet_count) relative to a specified baseline row, and (2) an equal-width histogram distributing values across a configurable number of bins. Both reports are computed locally from the supplied data with no external lookups.
