# oz0 index verify

> Usage and flags for oz0 index verify.

For: Operators and developers looking up a command.

Check a signed index.json as a server does before it takes a copy: a signature by an online key that the root key (--root-key, base64, or a key file) certified for this index, a certificate and an index that have not expired, and a payload that matches the schema. --print writes the payload.

With --detail-dir, every version's detail document must be in the folder, with the SHA-256 and size the index pins, and read as a listing whose compact form is the version's generated part, as an index's site checks.

## Usage

```bash
oz0 index verify <index.json> [flags]
```
