# Document Version Comparison — String Normalisation + Daily Sum Series

> Document Version Comparison — 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 2026-10-30).

Runs two local analytical reports on document version comparison data: string normalisation and a daily sum time series, for up to 200 rows of changed/total paragraph counts.

## 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 document-version-comparison-string-normalisation-daily-sum-series-56f33f05 -d '<json body>'
```

Example prompt: Can you run string normalisation and a daily sum series on these document version comparison records — I have 4 rows with fields like document_group, date, changed_paragraphs, and total_paragraphs — and I want the analysis on the changed_paragraphs field?

## When to prefer this

Choose this endpoint when you have document version comparison data with paragraph-level change counts and need two lightweight offline analytical reports — string normalisation and daily sum series — without any external API calls, predictions, or professional assessments. Ideal for agents processing editorial or content-tracking workflows where batch analysis of up to 200 records is sufficient and cost must be minimal ($0.01 per call).

## Known failure modes

- More than 200 rows submitted — request rejected at input validation
- Missing required fields (row_id, date, changed_paragraphs, or total_paragraphs) cause row-level errors
- Date strings not matching YYYY-MM-DD pattern fail validation
- Null numeric values may affect sum calculations if not handled
- Invalid field enum value (not 'changed_paragraphs' or 'total_paragraphs') causes rejection
- Payment not completed via x402 protocol results in 402 response

## How this service works

Document version comparison — String normalisation + Daily sum series: String normalisation + Daily sum series for supplied document version comparison records (changed_paragraphs, total_paragraphs). 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 derived solely from the supplied data: (1) a string normalisation report on document group labels and identifiers, and (2) a daily sum time series aggregating the selected numeric field (changed_paragraphs or total_paragraphs) by date. No external lookups or predictions are made. Results cover up to 200 input rows.
