## 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-required-cell-check-6048874a -d '<json body>'
```

Example prompt: Can you run a required-cell check on my maintenance imports CSV — it uses a comma delimiter and has columns maintenance_id, performed_on, asset_id, labour_hours, and parts_cost — and tell me which rows are missing required values?

## When to prefer this

Choose this endpoint when you need a lightweight, low-cost ($0.01 USDC) required-cell presence check specifically for maintenance import CSVs with up to 1000 rows. It is purpose-built for the maintenance records domain (maintenance_id, performed_on, asset_id, labour_hours, parts_cost) and handles quoted cells without external enrichment. Prefer it over generic CSV validators when you need a domain-specific preset and deterministic validation with no side effects.

## Known failure modes

- CSV exceeds 1000 rows — validation may be truncated or rejected
- Invalid delimiter character not in allowed enum causes parse error
- Cell length exceeds max_cell_length limit — row flagged or rejected
- Malformed CSV (unmatched quotes, inconsistent columns) causes parse failure
- Empty CSV string (minLength violation) returns error
- Numeric values outside specified minimum/maximum range flagged as invalid

## How this service works

Maintenance imports — Required cell check: Required cell check 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 required cell check report.

## Output

Returns a structured required-cell check report indicating which rows and columns have missing or invalid required values, based on the declared CSV schema with up to 1000 rows. Quoted cells are handled correctly, and the report covers blank required fields and out-of-range numeric values within the specified minimum/maximum bounds.
