## 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 job-execution-imports-header-contract-check-081f023f -d '<json body>'
```

Example prompt: Can you check if my job execution CSV has a valid header contract — here's the file with columns job_id, executed_on, worker_id, elapsed_seconds, processed_rows and comma-separated values, and the allowed categories are group-a and group-b?

## When to prefer this

Choose this endpoint when you need a fast, lightweight check that a job execution CSV file's header structure and column declarations conform to an expected contract before ingesting or processing the data. It is purpose-built for job execution import schemas (job_id, worker_id, elapsed_seconds, etc.) and supports category allow-listing and numeric range constraints. Prefer this over generic CSV validators when your use case is specifically job execution import data and you need a low-cost ($0.01 USDC) schema audit with quoted cell support.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- CSV is empty or missing headers — validation error returned
- Invalid delimiter specified — must be comma, semicolon, or tab
- Cell length exceeds max_cell_length threshold — flagged in report
- Malformed CSV (unclosed quotes, inconsistent columns) — parse error
- Allowed categories list exceeds 100 items — request rejected

## How this service works

Quoted cells supported; no external enrichment. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one CSV header contract check report.

## Output

Returns a header contract check report indicating whether the CSV's declared column headers conform to the expected schema, highlighting any mismatches, unexpected or missing columns, and any constraint violations such as invalid categories or out-of-range values, for up to 1000 rows.
