# Font Production Analytics — Numeric Row Ordering & Two-Measure Correlation

> Font Production Analytics — Numeric Row Ordering & Two-Measure Correlation 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).

Sorts font production records by numeric value and computes correlation between glyph_count and kerning_pairs across up to 200 rows, returning two independent 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-numeric-row-ordering-two-measure-correlation-24051cee -d '<json body>'
```

Example prompt: I have font production records for four typeface groups — can you sort them by glyph_count and also run a correlation between glyph_count and kerning_pairs? Here are the rows: row-1 group-a 2026-10-01 glyph_count=10 kerning_pairs=1, row-2 group-b 2026-10-02 glyph_count=20 kerning_pairs=2, row-3 group-a 2026-10-03 glyph_count=15 kerning_pairs=3, row-4 group-b 2026-10-04 glyph_count=30 kerning_pairs=4.

## When to prefer this

Choose this endpoint when you need fast, offline statistical analysis of font production records specifically — numeric ordering plus correlation between glyph count and kerning pairs — without requiring any external data lookups, predictions, or real-time services. It is ideal for type foundry pipelines or creative asset tracking workflows where you want two bundled analytical reports on up to 200 rows for a fixed low cost.

## Known failure modes

- Exceeding 200 rows returns a validation error
- Missing required fields (row_id, date, glyph_count, kerning_pairs) causes row rejection
- Invalid date format (non-YYYY-MM-DD) triggers a schema validation error
- Null values in both numeric fields for all rows may produce undefined correlation
- Selecting a field value outside the enum ['glyph_count','kerning_pairs'] returns a bad request error

## How this service works

Font production — Numeric row ordering + Two-measure correlation: Numeric row ordering + Two-measure correlation 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 two independent reports: (1) the submitted rows reordered by the selected numeric field (glyph_count or kerning_pairs) in ascending or descending rank, and (2) a correlation analysis between glyph_count and kerning_pairs across all submitted rows, including the correlation coefficient and supporting statistics. Both reports are computed locally with no external lookups.
