# Font Production Analytics — Numeric Distribution & Row Ordering

> Font Production Analytics — Numeric Distribution & Row Ordering 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).

Computes numeric distribution statistics and row ordering reports for font production records (glyph_count and kerning_pairs fields) across 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 font-production-analytics-numeric-distribution-row-ordering-120835b4 -d '<json body>'
```

Example prompt: Can you run a numeric distribution and row ordering analysis on my font production data? I have 4 fonts — row-1 (group-a, 2026-10-01, glyph_count: 320, kerning_pairs: 150), row-2 (group-b, 2026-10-02, glyph_count: 480, kerning_pairs: 220), row-3 (group-a, 2026-10-03, glyph_count: 210, kerning_pairs: 95), row-4 (group-b, 2026-10-04, glyph_count: 670, kerning_pairs: 310) — analyze by glyph_count.

## When to prefer this

Choose this endpoint when you have font production data with glyph_count and kerning_pairs metrics and need both a numeric distribution summary and a row ranking in a single call. It is purpose-built for typography/font production analytics rather than general-purpose statistical APIs, and bundles two reports for one low-cost payment. Best suited for batches up to 200 rows where offline, local computation (no external API calls) is acceptable.

## Known failure modes

- Missing required fields (row_id, date, asset_group, glyph_count, kerning_pairs) will cause validation errors
- Submitting more than 200 rows will be rejected (maxItems: 200)
- Null values for both glyph_count and kerning_pairs may degrade distribution accuracy
- Invalid date format (must match YYYY-MM-DD pattern) will fail schema validation
- Invalid field enum value (must be 'glyph_count' or 'kerning_pairs') will cause an error
- Payment of 0.01 USDC must be provided via x402 protocol; missing payment will result in 402 response

## How this service works

Font production — Numeric distribution + Numeric row ordering: Numeric distribution + Numeric row ordering 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 analytical reports: (1) a numeric distribution summary showing statistical spread (e.g. min, max, mean, quartiles, frequency distribution) of the selected field (glyph_count or kerning_pairs) across the submitted rows, and (2) a row ordering report ranking the submitted rows by the selected numeric field. Both reports are computed locally from the supplied data with no external lookups.
