## 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 workberry-x402-coverage-report-28678ca2 -d '<json body>'
```

Example prompt: Can you pull me an immutable aggregate timestamp-coverage report with a cutoff of today's date and include the reproducibility digest so I can verify the data provenance?

## When to prefer this

Choose this endpoint when you need a tamper-evident, reproducible coverage report tied to a specific timestamp cutoff — particularly for audit trails, compliance snapshots, or data provenance verification where the reproducibility digest provides cryptographic proof of consistency.

## Known failure modes

- Invalid or missing cutoff timestamp returns a 400 error
- Malformed request body causes a 422 validation error
- Payment failure or insufficient USDC balance returns a 402 Payment Required
- Service unavailability returns a 503 error
- Coverage data not yet available for requested cutoff returns an empty or partial result

## How this service works

Immutable aggregate timestamp-coverage report with cutoff and reproducibility digest.

## Output

Returns an immutable aggregate report containing timestamp coverage metrics, a cutoff date boundary, and a reproducibility digest (hash) that allows independent verification that the same inputs produce the same report output.
