## 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 accessibility-review-string-normalisation-numeric-interval-filter-1f23b7f4 -d '<json body>'
```

Example prompt: I have accessibility review data for several course groups — can you normalize the course_group strings and filter the rows where checked_resources is between 5 and 50? Here are my rows: row-1, group-a, 2026-10-01, checked_resources=10, remediated_resources=1; row-2, group-b, 2026-10-02, checked_resources=60, remediated_resources=2.

## When to prefer this

Choose this endpoint when you need to both clean/normalize string fields and filter accessibility review records by a numeric range for checked_resources or remediated_resources in a single call, without needing live lookups, predictions, or external data. Ideal for education accessibility audits processing up to 200 rows at low cost ($0.01 USDC per call for 2 reports).

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Invalid date format (not YYYY-MM-DD) — validation error
- minimum greater than maximum — interval is empty, returns zero rows
- Missing required fields (row_id, date, checked_resources, remediated_resources) — schema validation failure
- Numeric values outside allowed range (-1e12 to 1e12) — rejected

## How this service works

Accessibility review — String normalisation + Numeric interval filter: String normalisation + Numeric interval filter for supplied accessibility review records (checked_resources, remediated_resources). 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 up to 2 analytical reports covering: (1) normalised string fields for course_group and related text columns, and (2) rows from the input dataset whose selected numeric field (checked_resources or remediated_resources) falls within the specified minimum–maximum interval. Up to 200 input rows are processed locally with no external lookups.
