## 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-qbr-coverage-dataset-b5e88708
```

Example prompt: Can you download the QBR coverage dataset from TableProof and use it to check my data import — I want to see which records are missing, added, or changed compared to the original CSV export?

## When to prefer this

Choose this endpoint when you need to verify a specific QBR coverage data import by exact ID matching against a known original CSV export. It is best suited for post-migration audits, ETL pipeline validation, or any workflow where you need a bounded, structured diff of missing, added, or changed records in tabular CSV data. Prefer this over generic file diff tools when working with structured CSV data that has stable row identifiers.

## Known failure modes

- Payment not completed (402 response) — endpoint requires $19 USDC payment per call via x402 protocol
- ZIP file corrupt or incomplete if download is interrupted mid-stream
- Dataset may not match the user's specific import schema if column names differ
- Preview mode may limit the number of discrepancies shown without full payment
- Endpoint may return 404 if the specific dataset path (qbr-coverage.zip) is unavailable or rotated

## How this service works
