# Schema Conformity Record Quality Audit + Equal-Width Histogram

> Schema Conformity 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 2026-10-16).

Runs two analytical reports on schema conformity data — a record quality audit and an equal-width histogram — for up to 200 rows of valid_records/checked_records data.

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 schema-conformity-record-quality-audit-equal-width-histogram-dbf7f301 -d '<json body>'
```

Example prompt: Can you run a record quality audit and a 10-bin equal-width histogram on these schema conformity rows — I have valid_records and checked_records for 50 date-stamped entries across two dataset groups, and I want the histogram on the valid_records field?

## When to prefer this

Choose this endpoint when you need fast, offline statistical analysis of schema conformity data — specifically a combined quality audit plus histogram — without any external lookups or live data access. Ideal for data engineering pipelines, QA workflows, or compliance checks where you supply up to 200 rows of valid/checked record counts and need structured analytical output for a fixed low cost.

## Known failure modes

- More than 200 rows submitted — request rejected
- Missing required fields (row_id, date, valid_records, checked_records) — validation error
- Date field not matching YYYY-MM-DD pattern — schema error
- bin count outside 1–30 range — validation error
- Empty rows array — minimum 1 item required
- Field enum value not 'valid_records' or 'checked_records' — invalid input

## How this service works

Schema conformity — Record quality audit + Equal-width histogram: Record quality audit + Equal-width histogram for supplied schema conformity records (valid_records, checked_records). 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 record quality audit summarizing completeness, nulls, outliers, and validity metrics across the supplied conformity rows, and (2) an equal-width histogram over the selected field (valid_records or checked_records) divided into the specified number of bins, showing the distribution of values across all rows.
