## 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 transfer-record-imports-declared-column-projection-5e855ebb -d '<json body>'
```

Example prompt: Can you validate my transfer import CSV — it has columns transfer_id, executed_on, asset_id, sent_amount, and received_amount — using comma as delimiter, amounts between 0 and 5000000, and only allowing categories group-a and group-b?

## When to prefer this

Choose this endpoint when you need a lightweight, low-cost ($0.01 USDC) structural validation of a CSV transfer import file against a declared column contract — especially when you want to catch schema violations, out-of-range numeric values, or disallowed category values before importing. Best for files up to 1000 rows with known column layouts including transfer_id, executed_on, asset_id, sent_amount, and received_amount.

## Known failure modes

- CSV exceeds 1000 rows — only up to 1000 rows are processed
- CSV string exceeds 100000 character limit — request rejected
- Cell length exceeds max_cell_length — validation error flagged
- Delimiter mismatch causes incorrect column parsing
- Values outside minimum/maximum range flagged as violations
- Disallowed category values in asset_id column flagged
- Malformed quoted cells may cause parse errors
