# Record Routing — Keyed Dataset Comparison + Explicit Missing-Value Fill

> Record Routing — Keyed Dataset Comparison + 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 2026-10-23).

Compares two keyed record-routing datasets (accepted_records, rejected_records) across up to 200 rows and fills missing values, producing 2 analytical reports locally.

## 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 record-routing-keyed-dataset-comparison-explicit-missing-value-fill-e51102df -d '<json body>'
```

Example prompt: Compare my two record routing datasets — the primary one has rows like group-a on 2026-10-01 with 10 accepted_records and 1 rejected_records, and the other dataset has the same keys but slightly different values — fill any missing values and give me both the keyed comparison and the missing-value fill reports, focusing on the accepted_records field.

## When to prefer this

Choose this endpoint when you need to locally compare two keyed record-routing datasets (with accepted and rejected record counts) across up to 200 rows, and also want explicit missing-value fill — all in a single $0.01 call that produces two independent reports. Prefer it over generic diff tools when your data is already structured with row_id, dataset_group, and date keys. Not suitable for live lookups, predictions, or datasets exceeding 200 rows.

## Known failure modes

- More than 200 rows submitted — request exceeds row limit and will be rejected
- Missing required fields (row_id, dataset_group, date, accepted_records, rejected_records) cause validation errors
- Invalid date format (not YYYY-MM-DD) triggers pattern validation failure
- Numeric values outside allowed range (±1,000,000,000,000) cause schema rejection
- Empty rows array (minItems:1 not met) returns an error
- field enum value not one of accepted_records or rejected_records causes rejection

## How this service works

Record routing — Keyed dataset comparison + Explicit missing-value fill: Keyed dataset comparison + Explicit missing-value fill for supplied record routing records (accepted_records, rejected_records). 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 2 analytical reports: (1) a keyed dataset comparison showing differences between the primary and secondary routing datasets row by row, and (2) an explicit missing-value fill summary identifying and resolving null accepted_records or rejected_records values — all computed locally without external lookups.
