## 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-verify-data-import-by-exact-ids-2d3c2601
```

Example prompt: Can you run my original customers.csv and the imported version through TableProof to check if any records are missing, added, or changed — I want to verify the migration didn't corrupt anything?

## When to prefer this

Choose this endpoint when you need to verify CSV data imports by matching records on exact IDs and need a clear categorical breakdown of missing, added, and changed rows — especially useful after ETL jobs, system migrations, or third-party data handoffs where row-level integrity matters.

## Known failure modes

- CSVs with mismatched ID column names may fail to align records correctly
- Very large CSV files may exceed the bounded preview limit, returning only a partial diff
- Malformed CSV formatting (inconsistent delimiters, unescaped quotes) may cause parse errors
- Network or payment failure before processing returns no result
- ID columns not uniquely identifying rows may produce ambiguous or incorrect diff results

## 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 downloadable toolkit archive (binary ZIP) containing a bounded preview report of differences between the two CSVs, categorized into missing records (present in original but not imported), added records (present in imported but not original), and changed records (same ID but differing field values).
