# Document Readability Inputs — Numeric Row Ordering + Numeric Interval Filter

> Document Readability Inputs — Numeric Row Ordering + Numeric Interval Filter is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-26).

Sorts document readability records (sentence_count, word_count) by numeric order and filters rows within a specified numeric interval, returning two analytical reports for up to 200 rows.

## 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-readability-inputs-numeric-row-ordering-numeric-interval-cb252f79 -d '<json body>'
```

Example prompt: I have a set of document readability records with sentence counts and word counts for up to 50 rows — can you sort them by sentence_count and filter to only include rows where sentence_count is between 10 and 100, grouped by document group?

## When to prefer this

Choose this endpoint when you have up to 200 document readability records (sentence_count and word_count per row) and need both a numerically sorted ranking and an interval-filtered subset in a single $0.01 call. It is ideal for offline, local analytical workloads on pre-collected writing data where no live lookup, prediction, or external enrichment is needed. Prefer alternatives if you need NLP-based readability scoring, real-time document ingestion, or more than two reports per call.

## Known failure modes

- Fewer than 1 row or more than 200 rows submitted — request rejected
- Missing required fields (row_id, document_group, date, sentence_count, word_count) on any row — validation error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Minimum greater than maximum — may return empty filtered report
- Field enum value not 'sentence_count' or 'word_count' — validation error
- Payment not completed or insufficient USDC — request blocked

## How this service works

Document readability inputs — Numeric row ordering + Numeric interval filter: Numeric row ordering + Numeric interval filter for supplied document readability inputs records (sentence_count, word_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 independent analytical reports: one with rows numerically ordered by the specified field (sentence_count or word_count), and one with rows filtered to only those whose specified field value falls within the supplied minimum–maximum interval. Covers up to 200 input rows. No live lookup or external data is used — all computation is local.
