## 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 subscription-imports-declared-column-projection-feea721a -d '<json body>'
```

Example prompt: Can you validate this subscription import CSV — it uses comma delimiters, columns are subscription_id, started_on, plan_id, monthly_amount, seat_count, and the allowed plan categories are group-a and group-b? Make sure values are between 0 and 500000 and no cell exceeds 1000 characters.

## When to prefer this

Choose this endpoint when you need a fast, cheap ($0.01 USDC) server-side validation of a subscription-domain CSV against a declared column contract — especially when you need to enforce allowed categorical values, numeric bounds, cell length limits, and column presence before importing into a billing or subscription system. Prefer this over generic CSV validators when your data includes subscription-specific fields like plan_id, seat_count, and monthly_amount and you want a structured report rather than just a parse check.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- More than 1000 rows submitted — only first 1000 may be processed or error returned
- Invalid delimiter value (not comma, semicolon, or tab) — schema validation error
- Cell exceeds max_cell_length — validation failure flagged in report
- Numeric values outside minimum/maximum bounds — reported as out-of-range
- Disallowed category values not in allowed_categories list — flagged in report
- Malformed CSV with unmatched quotes — parse error returned
