# Join Coverage Analytics: Record Quality Audit + String Normalisation + Daily Sum Series

> Join Coverage Analytics: Record Quality Audit + String Normalisation + Daily Sum Series is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Runs three local analytical reports on join coverage data (matched_rows, source_rows): a record quality audit, string normalisation, and daily sum series — up to 200 rows per call.

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 join-coverage-analytics-record-quality-audit-string-normalisation-30b98248 -d '<json body>'
```

Example prompt: Can you run the three join coverage analytics reports — record quality audit, string normalisation, and daily sum series — on my dataset rows for groups 'group-a' and 'group-b' from October 2026, analysing the matched_rows field?

## When to prefer this

Choose this endpoint when you need three bundled analytical reports (quality audit, string normalisation, daily aggregation) on join coverage data in a single cheap call. Ideal for data engineers monitoring ETL pipelines, analysts checking match rates over time, or anyone needing a quick multi-faceted diagnostic on up to 200 rows of joined dataset records without requiring external lookups or live data access.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Missing required fields (row_id, dataset_group, date, matched_rows, source_rows) cause validation errors
- Date values not matching YYYY-MM-DD pattern will fail schema validation
- Null numeric values for both matched_rows and source_rows may reduce audit accuracy
- Invalid field enum value (anything other than 'matched_rows' or 'source_rows') causes rejection
- Payment of 0.01 USDC not provided or declined blocks execution

## How this service works

Join coverage — Record quality audit + String normalisation + Daily sum series: Record quality audit + String normalisation + Daily sum series for supplied join coverage records (matched_rows, source_rows). 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 returned for the submitted rows: (1) a record quality audit flagging issues in the supplied join coverage records, (2) a string normalisation report on text fields like row_id and dataset_group, and (3) a daily sum series aggregating the selected numeric field (matched_rows or source_rows) by date — all computed locally with no external lookups.
