# API Contracts Data Quality Suite — Record Audit, String Normalisation & Weighted Mean

> API Contracts Data Quality Suite — Record Audit, String Normalisation & Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Runs three local analytical reports on API contract records: record quality audit, string normalisation, and secondary-measure weighted mean for fields_checked and incompatible_fields columns.

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 api-contracts-data-quality-suite-record-audit-string-normalisation-5b368e4d -d '<json body>'
```

Example prompt: Can you run a quality audit, string normalisation, and weighted mean analysis on these API contract records — up to 200 rows with fields_checked and incompatible_fields values — grouped by component and dated from 2026-10-01, using fields_checked as the primary field?

## When to prefer this

Choose this endpoint when you need three bundled data-quality reports (audit, normalisation, weighted mean) on API contract records in a single low-cost call. Ideal for teams tracking API compatibility health over time who want offline, privacy-safe analysis without any live external lookup. Best when row count is under 200 and the data already resides locally or in a pipeline.

## Known failure modes

- Fewer than 1 or more than 200 rows submitted — request rejected
- Missing required fields (row_id, date, component, fields_checked, incompatible_fields) cause row-level errors
- Date strings not matching YYYY-MM-DD pattern are rejected
- Numeric values outside ±1,000,000,000,000 bounds fail validation
- Invalid field enum value (not 'fields_checked' or 'incompatible_fields') causes parameter error
- Payment of 0.01 USDC not provided or x402 handshake fails — request blocked

## How this service works

API contracts — Record quality audit + String normalisation + Secondary-measure weighted mean: Record quality audit + String normalisation + Secondary-measure weighted mean for supplied api contracts records (fields_checked, incompatible_fields). 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 co-delivered analytical reports: (1) a record quality audit flagging missing, malformed, or out-of-range values across the supplied rows; (2) a string normalisation report standardising text fields such as component names; (3) a secondary-measure weighted mean computed over the chosen numeric field (fields_checked or incompatible_fields). All computed locally with no external lookups. Covers up to 200 input rows per call.
