# Numeric Precision Comparisons — Duplicate Key Report + Explicit Missing-Value Fill

> Numeric Precision Comparisons — 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 2026-10-15).

Analyzes up to 200 rows of numeric source/transformed value pairs, producing a duplicate key report and an explicit missing-value fill report using local analytical engines.

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 numeric-precision-comparisons-duplicate-key-report-explicit-missing-e50704cd -d '<json body>'
```

Example prompt: I have 50 rows of source and transformed numeric values with some missing entries and possible duplicate row IDs — can you run a duplicate key report and fill the missing source_value fields using the median, grouped by dataset_group and date?

## When to prefer this

Choose this endpoint when you need both duplicate key detection and missing-value imputation on numeric source/transformed value pairs in a single low-cost call (0.01 USDC). It is ideal for lightweight data quality checks on datasets up to 200 rows where no external data, predictions, or professional assessments are needed — purely local, deterministic analytical processing.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- Numeric values outside the ±1,000,000,000,000 range are rejected
- Empty rows array returns an error
- Invalid enum value for field or method parameters causes validation error
- Payment not included or insufficient USDC results in 402 response

## How this service works

Numeric precision comparisons — Duplicate key report + Explicit missing-value fill: Duplicate key report + Explicit missing-value fill for supplied numeric precision comparisons records (source_value, transformed_value). 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: (1) a duplicate key report identifying rows that share the same row_id, and (2) an explicit missing-value fill report showing which rows had null source_value or transformed_value entries and what values were substituted using the chosen fill method (zero, mean, or median). No external lookups or predictions are made.
