# Build Artifacts Duplicate Key Report + Explicit Missing-Value Fill

> Build Artifacts Duplicate Key Report + Explicit 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 2026-10-30).

Analyzes build artifact records to identify duplicate row keys and fill missing numeric values using zero, mean, or median imputation

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 build-artifacts-duplicate-key-report-explicit-missing-value-fill-f0317a46 -d '<json body>'
```

Example prompt: I have up to 200 rows of build artifact records with fields like artifact_mb and build_seconds — can you run a duplicate key report on them and also fill in any missing artifact_mb values using the median?

## When to prefer this

Choose this endpoint when you need to simultaneously audit build artifact records for duplicate row keys and impute missing numeric values in a single cost-efficient call. It is purpose-built for build pipeline data with artifact_mb and build_seconds fields. Prefer it over generic data-cleaning tools when working with game-area-scoped build records up to 200 rows and you want both a duplicate report and a filled dataset in one operation at low cost ($0.01 USDC).

## Known failure modes

- Fewer than 1 row submitted — validation error
- More than 200 rows submitted — rejected with max-items error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- row_id missing or empty — required field error
- Invalid fill method enum value — schema validation failure
- Invalid field enum value — schema validation failure

## How this service works

Build artifacts — Duplicate key report + Explicit missing-value fill: Duplicate key report + Explicit missing-value fill for supplied build artifacts records (artifact_mb, build_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

Two independent analytical reports: (1) a duplicate key report identifying which row_id values appear more than once across the submitted records, and (2) an explicit missing-value fill report showing the original and imputed values for the selected numeric field (artifact_mb or build_seconds) using the chosen fill method (zero, mean, or median). No external data is fetched; all analysis is performed locally on the supplied rows.
