## 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-header-contract-check-2b3cd75f -d '<json body>'
```

Example prompt: Check if my maintenance import CSV has valid headers and data — here's the file with columns maintenance_id, performed_on, asset_id, labour_hours, and parts_cost, comma-delimited, with allowed categories group-a and group-b, and make sure no numeric value exceeds 1,000,000.

## When to prefer this

Use this endpoint when you need a lightweight, low-cost ($0.01) pre-flight check of a maintenance data CSV file before ingestion into a CMMS or data pipeline. It is purpose-built for the maintenance domain schema (maintenance_id, performed_on, asset_id, labour_hours, parts_cost) and supports quoted cells, configurable delimiters, category allowlists, and numeric range bounds — making it more specific and cheaper than a generic CSV validator for this use case.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- More than 1000 rows submitted — only first 1000 processed or error returned
- Invalid delimiter value not in allowed enum [',', ';', '\t'] — validation error
- Category values not in allowed_categories list — flagged as contract violations
- Numeric values outside min/max bounds — flagged as range violations
- Malformed CSV with unclosed quotes — parsing error returned
- Empty CSV string — rejected due to minLength constraint
