# API Contracts — Record Quality Audit + String Normalisation + Numeric Interval Filter

> API Contracts — Record Quality Audit + String Normalisation + Numeric Interval Filter 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).

Audits record quality, normalises strings, and filters by numeric interval for API contract records containing fields_checked and incompatible_fields columns — returning 3 independent analytical reports for up to 200 rows.

## 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-record-quality-audit-string-normalisation-numeric-5c37f242 -d '<json body>'
```

Example prompt: Can you run a record quality audit, string normalisation, and numeric interval filter on my API contract data? I have rows with fields_checked and incompatible_fields columns, and I want to filter where fields_checked is between 0 and 100.

## When to prefer this

Choose this endpoint when you need three bundled local analytical operations — quality audit, string normalisation, and numeric range filtering — on API contract records in a single low-cost call. It is best suited for batch offline analysis of up to 200 rows when no live data lookup, prediction, or external enrichment is required. Prefer this over separate single-purpose endpoints when cost efficiency ($0.01 for all three reports) and co-located analysis matter.

## Known failure modes

- Fewer than 1 or more than 200 rows submitted — rejected with validation error
- Invalid date format (not YYYY-MM-DD) causes row-level parse failure
- Null or missing row_id causes record rejection
- Minimum greater than maximum in interval filter produces empty filter result
- Non-numeric values in fields_checked or incompatible_fields cause type validation failure
- field enum value not one of fields_checked or incompatible_fields causes parameter rejection

## How this service works

API contracts — Record quality audit + String normalisation + Numeric interval filter: Record quality audit + String normalisation + Numeric interval filter 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 independent analytical reports covering: (1) a record quality audit highlighting missing, null, or malformed values in the supplied rows; (2) a string normalisation report for the component field; and (3) a numeric interval filter report identifying rows where the selected numeric field (fields_checked or incompatible_fields) falls within or outside the specified minimum/maximum range. All computed locally with no external lookups.
