# Font Production Data — Exact Row Deduplication + Two-Measure Correlation

> Font Production Data — Exact Row Deduplication + 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 2026-10-30).

Deduplicates font production records and computes a two-measure correlation between glyph_count and kerning_pairs for up to 200 rows, returning two analytical reports.

## 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-data-exact-row-deduplication-two-measure-correlation-f3ac099a -d '<json body>'
```

Example prompt: Can you deduplicate my font production records and run a correlation between glyph_count and kerning_pairs? I have about 50 rows across two asset groups — please give me both reports.

## When to prefer this

Choose this endpoint when you have font production tabular data (with glyph_count and kerning_pairs fields) and need both exact row deduplication and a two-measure correlation in a single low-cost call. It is best suited for small-to-medium datasets (up to 200 rows) where you want offline, deterministic analysis without external API dependencies, live data lookups, or predictions.

## Known failure modes

- Submission of more than 200 rows causes rejection
- Missing required fields (row_id, date, glyph_count, kerning_pairs) triggers validation error
- Malformed date strings not matching YYYY-MM-DD pattern cause input rejection
- Submitting fewer than 2 non-duplicate rows may make correlation computation undefined
- Null values in both glyph_count and kerning_pairs may reduce correlation reliability
- Payment of less than 0.01 USDC will result in request failure

## How this service works

Font production — Exact row deduplication + Two-measure correlation: Exact row deduplication + 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 analytical reports: (1) an exact row deduplication report identifying and removing fully duplicate rows from the submitted font production records, and (2) a two-measure correlation report quantifying the statistical relationship between glyph_count and kerning_pairs across the supplied dataset. No external lookups or predictions are made; all analysis is performed locally on the submitted data.
