# Font Production Analytics — Secondary-Measure Weighted Mean + Keyed Dataset Comparison

> Font Production Analytics — Secondary-Measure Weighted Mean + Keyed Dataset Comparison 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 secondary-measure weighted mean and performs a keyed dataset comparison on up to 200 font production records (glyph_count, kerning_pairs), returning 2 analytical reports.

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 font-production-analytics-secondary-measure-weighted-mean-keyed-cbd7e33c -d '<json body>'
```

Example prompt: Can you run a weighted mean analysis on my font production data using glyph_count as the field, and also compare it against this second dataset? I have about 50 rows with asset_group, date, glyph_count, and kerning_pairs for each row.

## When to prefer this

Choose this endpoint when you need both a weighted mean computation and a keyed cross-dataset comparison on font production records (glyph_count, kerning_pairs) in a single low-cost call. Ideal for comparing two font library versions or production batches offline without any external data lookups or predictions. Best suited for datasets up to 200 rows where both reports are needed simultaneously.

## Known failure modes

- More than 200 rows submitted — exceeds maximum row limit
- Missing required fields (row_id, asset_group, date, glyph_count, kerning_pairs) in any row
- Invalid date format — must match YYYY-MM-DD pattern
- Field enum value not one of glyph_count or kerning_pairs
- Null values in both datasets for a given key — comparison may be incomplete
- Payment not fulfilled via x402 protocol — request rejected

## How this service works

Font production — Secondary-measure weighted mean + Keyed dataset comparison: Secondary-measure weighted mean + Keyed dataset comparison for supplied font production records (glyph_count, kerning_pairs). 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 secondary-measure weighted mean for the selected field (glyph_count or kerning_pairs) across the supplied rows, and (2) a keyed dataset comparison between the primary and secondary datasets, both computed locally without external lookups.
