## 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 return-imports-cell-length-audit-2b441afd -d '<json body>'
```

Example prompt: Can you audit the cell lengths in my returns CSV file — use a max cell length of 200 characters, comma delimiter, and flag any cells that exceed the limit across these columns: return_id, received_on, reason_code, returned_units, restocking_fee?

## When to prefer this

Choose this endpoint when you need to enforce character-length constraints on return import CSV files specifically, and want a lightweight, low-cost ($0.01) validation report without external enrichment. It is well-suited for pre-upload data quality gates in e-commerce return pipelines where oversized fields would break downstream import systems. Prefer this over generic CSV validators when you need configurable max cell length, category allowlisting, and numeric range enforcement in one pass on returns data.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- max_cell_length set outside allowed range 1–5000 — validation error
- Invalid delimiter value supplied — must be comma, semicolon, or tab
- CSV is empty or missing required structure — parsing failure
- More than 100 allowed_categories specified — schema rejection
- Malformed CSV with unclosed quotes — parsing error

## Output

A cell length audit report for the submitted returns CSV, identifying rows and cells that violate the configured maximum character length, along with summary validation findings. The report covers up to 1000 rows and respects quoted cell formatting and the specified delimiter.
