Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability cloud-usage-imports-declared-column-projection-548c740f -d '<json body>'

Example prompt: Can you validate this cloud usage CSV for me — it has columns usage_id, reported_on, resource_id, used_units, and billed_amount, comma-delimited, with allowed categories group-a and group-b, and I want to make sure values stay between 0 and 1000000?

## When to prefer this

Choose this endpoint when you need to validate cloud usage or billing CSV data against a declared column contract before importing or processing it, particularly when you need to enforce category allowlists, value ranges, and cell length limits on structured cloud resource usage records. Best suited for FinOps, cloud cost management, and data pipeline pre-validation workflows where structured cloud billing data must meet a known schema contract.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- CSV has fewer than 1 character — rejected as empty
- More than 100 allowed_categories specified — schema validation error
- Cell value exceeds max_cell_length threshold — flagged in report
- Numeric values outside minimum/maximum bounds — contract violation reported
- Malformed CSV (unclosed quotes, inconsistent columns) — parse error
- Unsupported delimiter used — schema validation error
