# Vendor Evaluation — Category Frequencies + Base-100 Series

> Vendor Evaluation — Category Frequencies + Base-100 Series 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).

Analyzes up to 200 vendor evaluation records to produce two reports: category frequency distribution and a base-100 indexed time series, using supplied_score and maximum_score fields.

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 vendor-evaluation-category-frequencies-base-100-series-2a4ebf47 -d '<json body>'
```

Example prompt: Analyze these 50 vendor evaluation records — each has a row_id, company_group, date, supplied_score, and maximum_score — and give me both a category frequency report and a base-100 series indexed from row 0, using the supplied_score field.

## When to prefer this

Choose this endpoint when you have structured vendor evaluation data (supplied_score, maximum_score) and need both a categorical frequency breakdown and a normalized time-series index in a single low-cost call. It is ideal for offline/batch analytical tasks on up to 200 rows where no live data lookup, prediction, or external action is needed. Prefer this over generic BI tools when you want two complementary reports — frequency distribution and base-100 series — delivered together for $0.01 USDC.

## Known failure modes

- Fewer than 1 row submitted — request rejected
- More than 200 rows submitted — exceeds limit, request rejected
- Missing required fields (row_id, company_group, date, supplied_score, maximum_score) — validation error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- base_index out of range (0–199) — error if index exceeds row count
- Null scores in all rows for selected field — may produce empty or degenerate series
- Payment failure — endpoint returns 402 if USDC payment is not attached

## How this service works

Vendor evaluation — Category frequencies + Base-100 series: Category frequencies + Base-100 series for supplied vendor evaluation records (supplied_score, maximum_score). 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 independent analytical reports: (1) a category frequency report showing how often vendor evaluation scores fall into each score band, grouped by company_group and date; and (2) a base-100 indexed series showing relative score movement from a specified baseline row — all computed locally from the supplied rows, with no external lookups.
