## 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-csv-header-contract-check-840ef32d -d '<json body>'
```

Example prompt: Can you check whether my application processing CSV has the right headers and valid data? It uses a comma delimiter, columns are application_id, received_on, role_id, stage_duration_days, and assessment_score, and the allowed category values are group-a and group-b — just validate the header contract and flag any issues.

## When to prefer this

Choose this endpoint when you need lightweight, low-cost CSV schema validation specifically for application processing import files — particularly when you want to enforce column headers, allowed categorical values, numeric bounds, and cell length limits without any external data enrichment. Ideal as a pre-import gate in automated pipelines handling recruitment or application-stage data.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- More than 1000 rows submitted — validation may be truncated or refused
- Invalid delimiter specified — parsing errors
- Malformed CSV (unmatched quotes, inconsistent columns) — parse failure
- Allowed categories list exceeds 100 items — input rejected
- Cell length exceeds max_cell_length — flagged as violation
- Numeric values outside min/max bounds — flagged as contract breach

## How this service works

Application processing imports — Header contract check: Header contract check 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 header contract check report.

## Output

Returns a header contract check report indicating whether the submitted CSV conforms to the declared schema — including column presence/order, allowed category values, cell length limits, numeric bounds compliance, and any row-level violations across up to 1000 rows.
