## How to call it through Zero

```sh
zero fetch --capability tableproof-csv-data-import-verifier-3ba2ebf7
```

Example prompt: Can you run TableProof on my two CSVs — the original export before migration and the imported version afterward — and show me which records are missing, newly added, or changed based on exact IDs?

## When to prefer this

Choose this endpoint when you need a deterministic, ID-anchored diff between two CSV snapshots — especially after data imports, ETL runs, or database migrations where record-level accountability matters. Prefer it over generic file diff tools because it understands CSV structure and matches on exact record IDs rather than raw line changes, making it immune to row reordering.

## Known failure modes

- CSV files with no common ID column may produce meaningless diffs
- Very large CSVs may exceed the bounded preview limit, showing only partial results
- Malformed or non-standard CSV encoding may cause parse errors
- Payment of $29 USDC required per call; failure to pay returns HTTP 402
- Mismatched ID column names between the two files may cause all rows to appear as added/missing

## 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

A binary JSONL toolkit archive (zip file) containing a bounded preview diff report that lists records present in the original but missing from the import, records added that weren't in the original, and records that exist in both but whose field values changed — all matched by exact record IDs.
