## 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 campaign-imports-cell-length-audit-bb1a546d -d '<json body>'
```

Example prompt: Check this campaign CSV for cell length violations — use a comma delimiter, max cell length of 255 characters, and flag anything outside those bounds: campaign_id,reported_on,channel_id,spend_amount,attributed_revenue\nrecord-a,2026-01-01,group-a,10,2

## When to prefer this

Choose this endpoint when you need to enforce a declared cell length contract on campaign import CSV data before ingestion or handoff, particularly when working with marketing performance data (campaign_id, channel, spend, revenue) and you need a cheap, fast, offline audit without external enrichment or transformation.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- max_cell_length set outside allowed range (1–5000) — validation error
- delimiter not one of comma, semicolon, or tab — schema error
- CSV contains zero rows or is empty — validation error
- More than 100 allowed_categories supplied — schema error
- Malformed CSV that cannot be parsed — parsing error
