## 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 csv-import-preflight-9b910e8f -d '<json body>'
```

Example prompt: Can you run a preflight inspection on this public CSV data to check for quoting errors, mismatched column counts, and any spreadsheet-formula prefixes before I import it — mark it as public data and confirm no personal info is included?

## When to prefer this

Choose this endpoint when you need a read-only, non-destructive preflight check on a CSV file before importing it into a database or pipeline — specifically when you need to catch quoting errors, formula-injection prefixes, column count inconsistencies, or scalar type mismatches without any risk of data modification. It is best suited for public or synthetic (non-personal) data up to 32 KiB. Prefer this over general-purpose CSV parsers when you need a safety-focused inspection that explicitly avoids executing or repairing cell content.

## Known failure modes

- Input exceeds 32 KiB limit — request rejected
- dataClass not set to 'public' or 'synthetic' — validation error
- nonpersonalMetadata not set to true — request rejected
- Malformed or unparseable CSV structure — inspection may return partial results
- Output exceeds 65 KB limit — truncated or error response

## How this service works

Inspect supplied CSV quoting, declared scalar types, column counts and spreadsheet-formula prefixes without executing or repairing cells. Public/synthetic nonpersonal input only; 32 KiB input, 65 KB output. Result retention: 24 hours; minimal receipt metadata: 90 days. Local validation only; deployment and model spending on hold.

## Output

A preflight inspection report detailing CSV quoting problems, column count mismatches, detected spreadsheet-formula prefixes, and scalar type declaration issues — all without executing or repairing any cell content. Results are retained for 24 hours; minimal receipt metadata is kept for 90 days.
