## 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 maintenance-imports-cell-length-audit-be9fa993 -d '<json body>'
```

Example prompt: Can you audit this maintenance CSV for cell length violations — max 200 characters per cell, comma-delimited, and only allow categories 'group-a' and 'group-b'? Here's the CSV: maintenance_id,performed_on,asset_id,labour_hours,parts_cost\nrec-001,2026-01-15,group-a,8,150

## When to prefer this

Choose this endpoint when you need a lightweight, low-cost ($0.01) cell-level length and category validation specifically for maintenance import CSVs, particularly when you want to enforce a declared table contract before ingesting data into a maintenance system. It is ideal for pre-ETL quality checks on structured maintenance records with up to 1000 rows, where no external data enrichment is needed and the audit scope is limited to cell length and allowed categorical values.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- max_cell_length out of range (must be 1–5000) — validation error
- Invalid delimiter supplied (must be comma, semicolon, or tab)
- CSV is malformed or unparseable — audit may return parsing error
- More than 100 allowed_categories supplied — request rejected
- Empty CSV string submitted — validation error

## How this service works

Maintenance imports — Cell length audit: Cell length audit for Maintenance imports. Validate a declared CSV table contract, up to 1000 rows. Quoted cells supported; no external enrichment. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one CSV cell length audit report.

## Output

Returns a cell length audit report indicating which rows and cells in the CSV violate the declared max cell length constraint, along with any category violations, covering up to 1000 rows of the submitted maintenance import CSV.
