# File Ingestion – Adjacent Row Changes Analytics

> File Ingestion – Adjacent Row Changes Analytics is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-17).

Computes adjacent (period-over-period) row-level changes for file ingestion metrics (loaded bytes or parse errors) across up to 200 supplied dated records.

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 file-ingestion-adjacent-row-changes-analytics-2bc6a2de -d '<json body>'
```

Example prompt: Can you run an adjacent row changes report on my file ingestion data — here are 4 records with dates, sources, loaded_bytes, and parse_errors — and analyze the loaded_bytes field for period-over-period changes?

## When to prefer this

Choose this endpoint when you need a lightweight, low-cost ($0.01) period-over-period delta report on sequential file ingestion rows without needing forecasts, enrichment, or aggregations — especially when you already have typed records with dates, source labels, loaded_bytes, and parse_errors ready to submit.

## Known failure modes

- Empty or malformed rows array returns a validation error
- Date strings not matching YYYY-MM-DD pattern are rejected
- Field value not in enum ['loaded_bytes','parse_errors'] returns a validation error
- More than 200 rows submitted causes a request rejection
- Numeric values outside ±1,000,000,000,000 are rejected
- Payment of 0.01 USDC not included or invalid causes a 402 error

## How this service works

File ingestion - Adjacent row changes: Adjacent row changes for File ingestion. Up to 200 supplied typed records. Local descriptive analytics; no enrichment or forecast. One of 25 new profiles across 20 shared operations in this industry. 0.01 USDC includes one bounded adjacent row changes report.

## Output

A bounded descriptive analytics report showing row-to-row (adjacent period) changes for the selected numeric field (loaded_bytes or parse_errors) across the submitted ingestion records, including deltas between consecutive entries without enrichment or forecasting.
