# Vendor Evaluation — Daily Sum Series + IQR Outlier Flags

> Vendor Evaluation — Daily Sum Series + IQR Outlier Flags 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 daily sum time series and IQR-based outlier flags for vendor evaluation records (supplied_score, maximum_score) 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-daily-sum-series-iqr-outlier-flags-3fc30ec5 -d '<json body>'
```

Example prompt: Can you run a daily sum series and IQR outlier analysis on these vendor evaluation records? I have scores for groups 'alpha' and 'beta' across dates in Q4 — use the supplied_score field and flag any outlier days.

## When to prefer this

Choose this endpoint when you need both a daily aggregated time series and IQR-based statistical outlier detection on vendor evaluation data in a single call. It is ideal for batch offline analysis of up to 200 pre-collected vendor scoring rows where no live data lookup or external enrichment is needed. Prefer it over generic analytics tools when working specifically with company-grouped vendor records containing supplied and maximum score fields.

## Known failure modes

- Empty or missing rows array returns an error
- rows exceeding 200 items are rejected
- invalid date format (not YYYY-MM-DD) causes validation failure
- null values in supplied_score or maximum_score may affect aggregation results
- invalid field enum value (not 'supplied_score' or 'maximum_score') causes rejection

## How this service works

Vendor evaluation — Daily sum series + IQR outlier flags: Daily sum series + IQR outlier flags 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: (1) a daily sum time series aggregating the selected field (supplied_score or maximum_score) by date, and (2) IQR-based outlier flags identifying which dates or records fall outside the interquartile range, based on the supplied input rows. No external data is fetched; all analysis is performed on the provided records.
