## 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 api-usage-imports-required-cell-check-f326f7c2 -d '<json body>'
```

Example prompt: Check my API usage CSV for missing required cells — it has columns usage_id, observed_on, endpoint_id, request_count, and error_count, and uses a comma delimiter. Here's the data: 'record-a,2026-01-01,group-a,10,2\nrecord-b,2026-01-02,group-b,20,3'. Make sure all required fields are present across all rows.

## When to prefer this

Choose this endpoint when you need to validate that all required cells are present in a CSV file representing API usage imports (with columns like usage_id, observed_on, endpoint_id, request_count, error_count) before ingesting the data into a pipeline. It is purpose-built for this specific schema and supports quoted cells, configurable delimiters, and allowed category constraints, making it more targeted than a generic CSV validator.

## Known failure modes

- CSV exceeds 1000 rows — only up to 1000 rows supported
- CSV string exceeds 100,000 character limit
- Invalid delimiter specified (must be comma, semicolon, or tab)
- Cell content exceeds max_cell_length limit
- Malformed CSV that cannot be parsed
- Empty CSV string submitted
