# Vendor Evaluation — Base-100 Series + Keyed Dataset Comparison

> Vendor Evaluation — Base-100 Series + 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 2026-10-23).

Generates two analytical reports for vendor evaluation data: a Base-100 index series and a keyed dataset comparison, using supplied_score and maximum_score fields across 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 vendor-evaluation-base-100-series-keyed-dataset-comparison-15eb085b -d '<json body>'
```

Example prompt: I have two sets of vendor evaluation records for groups A and B across Q4 2026 — each row has a row_id, company_group, date, supplied_score, and maximum_score, up to 150 rows per dataset. Can you run a Base-100 series and keyed dataset comparison on them using the supplied_score field?

## When to prefer this

Choose this endpoint when you need two simultaneous analytical views — a Base-100 normalized time series and a keyed cross-dataset comparison — on vendor evaluation data (supplied_score, maximum_score) in a single paid call. It is ideal for procurement or supplier performance workflows where you want to index scores to a baseline and directly compare two datasets by shared row keys, all without any external data lookups or live predictions.

## Known failure modes

- Rows array is empty or exceeds 200 items — validation error returned
- Missing required fields (row_id, company_group, date, supplied_score, maximum_score) on any row — schema validation failure
- Date field does not match YYYY-MM-DD pattern — rejected with pattern mismatch error
- Null values in supplied_score or maximum_score may produce incomplete analytics for affected rows
- Mismatched row_ids between primary and secondary datasets may result in unmatched keys in the comparison report
- Payment of 0.01 USDC not completed — request rejected before processing

## How this service works

Vendor evaluation — Base-100 series + Keyed dataset comparison: Base-100 series + Keyed dataset comparison 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

Returns two analytical reports derived from the supplied vendor evaluation rows: (1) a Base-100 index series normalizing the chosen field (supplied_score or maximum_score) relative to a base period, enabling trend comparison across company groups and dates; and (2) a keyed dataset comparison aligning rows by key between the primary and secondary datasets to surface differences. All computation is performed locally with no external lookups.
