## 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 tableproof-csv-data-import-verifier-by-exact-ids-0662e75d -d '<json body>'
```

Example prompt: Can you verify my data import by comparing these two CSV files — the original export and the post-import export — and tell me which records are missing, added, or changed based on their IDs?

## When to prefer this

Choose this endpoint when you need to verify the fidelity of a CSV-based data import or migration by exact record IDs. It is ideal for post-ETL audits, database migration checks, and vendor data onboarding validation where you need a structured diff of missing, added, and changed rows rather than a visual file comparison.

## Known failure modes

- Malformed or missing packages array input returns a validation error
- CSV files with no common ID column cannot be compared and may return an error
- Very large datasets may be truncated to the bounded preview limit
- Mismatched ID formats between original and import may cause false positives
- Network timeout if payload is too large

## How this service works

Compare original and imported CSV exports by exact IDs. Find missing, added and changed records with a free bounded preview.

## Output

Returns a bounded preview diff report identifying: records present in the original but missing from the import, records added that weren't in the original, and records whose field values changed — all keyed by exact record IDs.
