# Crawl Response Observations — Duplicate Key Report + Adjacent Row Changes

> Crawl Response Observations — Duplicate Key Report + Adjacent Row Changes is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-06).

Analyzes crawl response observation rows (status_code, response_ms) to produce a duplicate key report and adjacent row change detection report.

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 crawl-response-observations-duplicate-key-report-adjacent-row-changes-2915e798 -d '<json body>'
```

Example prompt: Check my crawl response observations for duplicate row keys and adjacent row changes — here are up to 200 rows with fields row_id, site_group, date, status_code, and response_ms; run both reports on the status_code field.

## When to prefer this

Choose this endpoint when you need to audit crawl response observation datasets for duplicate row identifiers and sequential value changes in a single call. It is best suited for data quality checks on web crawl logs where you have up to 200 structured records and need both a deduplication report and a change-detection report without any live lookups or external data enrichment.

## Known failure modes

- Input array exceeds 200 rows — request will be rejected or truncated
- Missing required fields (row_id, site_group, date, status_code, response_ms) cause validation errors
- Invalid date format (must match YYYY-MM-DD) triggers schema rejection
- Invalid field enum value (must be 'status_code' or 'response_ms') returns error
- Empty rows array rejected due to minItems:1 constraint

## How this service works

Crawl response observations — Duplicate key report + Adjacent row changes: Duplicate key report + Adjacent row changes for supplied crawl response observations records (status_code, response_ms). 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 independent analytical reports: (1) a duplicate key report identifying rows sharing the same key values, and (2) an adjacent row changes report showing where the selected field (status_code or response_ms) changes between consecutive rows. Covers up to 200 input rows using local analytical engines with no external lookups.
