# Data Catalog Coverage — Record Quality Audit + Equal-Width Histogram

> Data Catalog Coverage — Record Quality Audit + Equal-Width Histogram 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).

Runs a record quality audit and equal-width histogram analysis on data catalog coverage records (documented_fields, total_fields) for up to 200 rows, returning two independent 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 data-catalog-coverage-record-quality-audit-equal-width-histogram-2f6589d0 -d '<json body>'
```

Example prompt: Can you run a record quality audit and a 10-bin equal-width histogram on my data catalog coverage records for documented_fields? I have rows for dataset groups 'finance' and 'ops' with dates in October 2025 — here's the data: row-1, finance, 2025-10-01, 80 documented, 100 total; row-2, ops, 2025-10-02, 45 documented, 90 total.

## When to prefer this

Choose this endpoint when you need fast, local, supply-side analytical computation on data catalog coverage records — specifically when you want both a quality audit and a histogram in a single call for up to 200 rows without any external data lookups or predictions. Ideal for data governance workflows where you already have the records and need rapid statistical summaries.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Missing required row fields (row_id, dataset_group, date, documented_fields, total_fields) causes validation error
- Invalid date format (not YYYY-MM-DD) causes schema rejection
- Bins value outside 1–30 range causes validation error
- Non-numeric values in documented_fields or total_fields where number expected
- Payment of 0.01 USDC not provided — x402 payment required before response

## How this service works

Data catalog coverage — Record quality audit + Equal-width histogram: Record quality audit + Equal-width histogram for supplied data catalog coverage records (documented_fields, total_fields). 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) a record quality audit identifying issues such as null values, out-of-range numbers, or anomalies in documented_fields and total_fields; and (2) an equal-width histogram showing the frequency distribution of the selected field (documented_fields or total_fields) across the specified number of bins. Both reports are computed locally with no external lookups.
