## 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 application-processing-imports-declared-column-projection-f472c492 -d '<json body>'
```

Example prompt: Can you validate this application processing CSV against its declared column contract — I need to check that role_id values are only 'group-a' or 'group-b', assessment_score is between 0 and 100, and stage_duration_days isn't negative? Here's the CSV data with comma delimiter.

## When to prefer this

Choose this endpoint when you need to validate application processing import CSV files against a declared column contract, specifically checking numeric ranges, allowed categorical values, and cell length constraints. It is purpose-built for HR/recruiting application data schemas (application_id, received_on, role_id, stage_duration_days, assessment_score) and is more appropriate than generic CSV validators when you need preset domain-specific projection logic without external enrichment.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- Row count exceeds 1000-row maximum — truncation or error
- Invalid delimiter specified — must be comma, semicolon, or tab
- Malformed CSV with unmatched quotes — parse error returned
- allowed_categories list exceeds 100 items — rejected
- Cell length exceeds max_cell_length threshold — flagged as violation
- minimum greater than maximum value — constraint conflict error

## How this service works

Application processing imports — Declared column projection: Declared column projection for Application processing 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 declared column projection report.

## Output

Returns a declared column projection report for the submitted CSV, including validation status per column, rows processed (up to 1000), constraint violations (out-of-range numeric values, disallowed category values, oversized cells), and an overall pass/fail contract status.
