# Vendor Evaluation — Base-100 Series + Secondary-Measure Weighted Mean

> Vendor Evaluation — Base-100 Series + Secondary-Measure Weighted Mean 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).

Computes a Base-100 index series and a secondary-measure weighted mean for up to 200 vendor evaluation score records, returning two analytical reports from local engines.

## 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-secondary-measure-weighted-mean-fc46d326 -d '<json body>'
```

Example prompt: I have vendor evaluation records for groups A and B from Q4 2025 — can you normalize the supplied_score field into a Base-100 index starting from the first row and also compute the secondary-measure weighted mean across all 200 rows?

## When to prefer this

Choose this endpoint when you have structured vendor evaluation records with numeric scores and need both a Base-100 time-indexed normalization and a weighted mean — especially when working offline without live data lookups, and when processing up to 200 rows at $0.01 USDC for both reports in a single call.

## Known failure modes

- Exceeds 200-row limit — request is rejected or truncated
- Missing required fields (row_id, supplied_score, maximum_score, date, company_group) cause validation errors
- base_index out of range (must be 0–199) causes error
- Null values in supplied_score or maximum_score may affect weighted mean accuracy
- Invalid date format (non-YYYY-MM-DD) rejected by pattern validation
- Maximum_score of zero causes division error in Base-100 normalization

## How this service works

Vendor evaluation — Base-100 series + Secondary-measure weighted mean: Base-100 series + Secondary-measure weighted mean 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 reports: (1) a Base-100 index series showing each row's supplied_score or maximum_score normalized relative to the chosen base index row, and (2) a secondary-measure weighted mean summarizing aggregate performance. All computation is performed locally with no external lookups or predictions.
