## 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 fact-check-workflow-grouped-numeric-summary-row-ordering-71aa5ecd -d '<json body>'
```

Example prompt: Can you run a grouped numeric summary and row ordering on my fact-check workflow data — here are 4 rows with channel groups 'group-a' and 'group-b', dates from 2026-10-01 to 2026-10-04, claims_reviewed values of 10, 20, 15, 30, and references_collected of 1, 2, 3, 4 — use claims_reviewed as the primary field?

## When to prefer this

Choose this endpoint when you have up to 200 rows of fact-check workflow data with claims_reviewed and references_collected metrics and need both a grouped aggregate summary by channel group and a numerically ranked row list in a single low-cost call. It is ideal for editorial analytics, newsroom reporting pipelines, or audit workflows where you supply the data directly and need fast offline computation without live lookups or external dependencies.

## Known failure modes

- Missing required fields (row_id, channel_group, date, claims_reviewed, references_collected) causes validation error
- Date values not matching YYYY-MM-DD pattern are rejected
- Submitting more than 200 rows exceeds the row limit and may be rejected
- Null numeric values in the selected field may affect ordering output
- Invalid field enum value (anything other than claims_reviewed or references_collected) causes an error

## How this service works

Fact check workflow — Grouped numeric summary + Numeric row ordering: Grouped numeric summary + Numeric row ordering for supplied fact check workflow records (claims_reviewed, references_collected). 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 reports: (1) a grouped numeric summary aggregating claims_reviewed or references_collected by channel_group, and (2) a numerically ordered ranking of the input rows by the selected field — both computed locally from the supplied data without any external lookups.
