# Fact Check Workflow — Grouped Numeric Summary + Numeric Interval Filter

> Fact Check Workflow — Grouped Numeric Summary + Numeric Interval Filter is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-02).

Computes a grouped numeric summary and applies a numeric interval filter on user-supplied fact check workflow records (claims_reviewed, references_collected) for up to 200 rows.

## 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-numeric-interval-filter-722cc4bc -d '<json body>'
```

Example prompt: Analyze my fact check workflow data — I have 4 rows with channel groups 'group-a' and 'group-b', dates from 2026-10-01 to 2026-10-04, and claims_reviewed values of 10, 20, 15, 30 with references_collected of 1, 2, 3, 4. Give me a grouped numeric summary and filter to only rows where claims_reviewed is between 0 and 25.

## When to prefer this

Choose this endpoint when you have up to 200 pre-collected fact check workflow records and need both a grouped statistical summary by channel and a numeric range filter in a single call, at minimal cost ($0.01 USDC for both reports). Prefer this over general-purpose analytics tools when your data is already structured with channel_group, date, claims_reviewed, and references_collected fields. Not suitable for live data fetching, prediction, or professional editorial assessment.

## Known failure modes

- Fewer than 1 row provided — request rejected (minItems:1 violated)
- More than 200 rows provided — request rejected (maxItems:200 exceeded)
- Invalid date format (not YYYY-MM-DD) — row validation error
- Numeric values outside ±1,000,000,000,000 range — schema validation error
- Missing required fields (row_id, channel_group, date) — per-row validation failure
- Field enum value not 'claims_reviewed' or 'references_collected' — rejected
- minimum greater than maximum — may return empty filter result

## How this service works

Fact check workflow — Grouped numeric summary + Numeric interval filter: Grouped numeric summary + Numeric interval filter 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 analytical reports: (1) a grouped numeric summary showing aggregate statistics (e.g. count, mean, sum) for claims_reviewed and references_collected broken down by channel_group, and (2) a filtered subset of input rows where the selected field (claims_reviewed or references_collected) falls within the specified minimum–maximum interval. All computation is performed locally on the supplied data with no external lookups.
