> Strale Data Quality Check is a paid API for AI agents from api.strale.io, paid per call via x402, $0.0216/call, status unknown (last checked 2026-09-15).

Validates a JSON array of objects against custom rules (email_format, range, pattern, etc.) or auto-detects issues, returning a quality score and field-level report

## 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-strale-io-18dad88d
```

Example prompt: Check the data quality of these user records and flag any issues — use rules for email_format on the 'email' field and a range of 0–120 on the 'age' field: [{"name":"Alice","email":"alice@example.com","age":25},{"name":"Bob","email":"not-an-email","age":999}]

## When to prefer this

Use this endpoint when you need programmatic, rule-based data validation with a structured quality score and field-level breakdown — especially when you have JSON records to check for format compliance, range violations, or pattern mismatches before ingesting into a pipeline or database.

## Known failure modes

- Missing required 'data' query parameter returns error
- Malformed JSON array causes parse error
- Invalid rule type (e.g. unsupported rule name) may be ignored or return error
- Empty data array returns score of 100 with no issues
- Very large arrays may time out or be truncated

## How this service works

Check data quality with custom rules (email_format, range, pattern, etc.) or auto-detect issues. Returns quality score and field-level report. Algorithmic.

## Output

Returns an overall quality score (0–100) and a field-level report identifying which records and fields failed which rules, including auto-detected anomalies if no rules are specified.
