## 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 commercial-proposal-comparisons-record-quality-audit-string-f22307ef -d '<json body>'
```

Example prompt: Can you run the record quality audit, string normalisation, and two-measure correlation reports on my commercial proposal data? I have rows with row IDs like 'row-1', company groups 'acme' and 'globex', dates in 2026, quoted amounts ranging from $5000 to $45000, and delivery days from 10 to 90.

## When to prefer this

Choose this endpoint when you need offline, local analytical processing of commercial proposal or vendor bid data — specifically when you want all three of record quality auditing, string normalisation, and two-measure correlation in a single cheap call (0.01 USDC) without needing live data lookups, ML predictions, or external enrichment. Ideal for procurement analysts or agents doing pre-report data hygiene on up to 200 rows of structured bid data.

## Known failure modes

- Fewer than 1 row or more than 200 rows submitted — request rejected
- Missing required fields (row_id, company_group, date, quoted_amount, delivery_days) on any row — validation error
- Date field not matching YYYY-MM-DD pattern — schema validation failure
- Numeric fields outside allowed range (-1e12 to 1e12) — schema rejection
- Insufficient numeric variance in quoted_amount or delivery_days for meaningful correlation — correlation report may return low-confidence or undefined result

## How this service works

Commercial proposal comparisons — Record quality audit + String normalisation + Two-measure correlation: Record quality audit + String normalisation + Two-measure correlation for supplied commercial proposal comparisons records (quoted_amount, delivery_days). Up to 200 rows; 3 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 3 supplied-data reports for up to 200 rows.

## Output

Three independent analytical reports: (1) a record quality audit flagging missing, null, or out-of-range values across rows; (2) a string normalisation report cleaning and standardising company_group and other string fields; and (3) a two-measure correlation report quantifying the statistical relationship between quoted_amount and delivery_days across the supplied rows. All analysis is performed locally on the supplied data with no external lookups.
