# Compositing Graphs IQR Outlier Flags + Missing-Value Fill

> Compositing Graphs IQR Outlier Flags + Missing-Value Fill is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-17).

Runs IQR-based outlier detection and explicit missing-value imputation on compositing graph records (node_count, render_seconds) — up to 200 rows, two reports per call.

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 compositing-graphs-iqr-outlier-flags-missing-value-fill-befe45ae -d '<json body>'
```

Example prompt: Can you flag IQR outliers and fill missing values in my compositing graph data using median imputation? I have about 50 rows with node_count and render_seconds fields — here's the dataset.

## When to prefer this

Choose this endpoint when you need both IQR outlier flagging AND missing-value imputation on compositing graph data (node_count or render_seconds) in a single low-cost call. It is ideal for data quality checks on rendering pipeline metrics before downstream analysis or reporting, and is purpose-built for the compositing graph schema with asset_group and date dimensions.

## Known failure modes

- Exceeding 200 rows returns a validation error
- Missing required fields (row_id, date, asset_group) cause schema rejection
- Invalid date format (non-YYYY-MM-DD) triggers pattern validation failure
- Numeric values outside ±1,000,000,000,000 range are rejected
- Empty rows array returns an error
- Invalid enum for method or field causes request rejection

## How this service works

Compositing graphs — IQR outlier flags + Explicit missing-value fill: IQR outlier flags + Explicit missing-value fill for supplied compositing graphs records (node_count, render_seconds). 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 independent analytical reports per call: (1) IQR outlier flags identifying which rows have statistically anomalous values for the selected field, and (2) a missing-value fill report showing which null/missing entries were imputed and with what value (zero, mean, or median). Results are computed locally without external lookups.
