## 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 content-length-observations-record-quality-audit-adjacent-row-changes-519292db -d '<json body>'
```

Example prompt: Can you run a record quality audit and adjacent row changes analysis on my word_count observations? I have about 50 rows with row IDs, site groups, and dates ranging from 2025-01-01 to 2025-02-19 — I want both reports back.

## When to prefer this

Choose this endpoint when you need a quick, low-cost dual-report analysis (quality audit + sequential change detection) on tabular content length data without requiring any external lookups, predictions, or professional assessment. Ideal for data pipeline validation, SEO content audits, or pre-ingestion quality checks on word count or heading count datasets of up to 200 rows.

## Known failure modes

- Fewer than 1 row submitted — validation error
- More than 200 rows submitted — request rejected or truncated
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Missing required fields (row_id, site_group, date, word_count, heading_count) — error response
- Invalid field enum value (not word_count or heading_count) — schema rejection
- Payment not included or insufficient — 402 Payment Required

## How this service works

Content length observations — Record quality audit + Adjacent row changes: Record quality audit + Adjacent row changes for supplied content length observations records (word_count, heading_count). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.

## Output

Returns two analytical reports: (1) a record quality audit identifying issues such as nulls, out-of-range values, or malformed records across the submitted rows; and (2) an adjacent row changes report showing value deltas between consecutive rows for the selected field (word_count or heading_count). Both reports are generated locally with no external lookups.
