# Namespaces

The Cloudflare Key Transparency API is organized in namespaces, each one representing a Log monitored by Cloudflare Auditor. If you want to register a namespace, contact us.

## Create a namespace

The following fields are required when making a `POST` request:

* `name`
* `public`
* `root`
* `signature_version`:  
  * 0x0001 for [Protobuf serialisation ↗](https://github.com/cloudflare/plexi/blob/main/plexi%5Fcore/src/proto/specs/types.proto) Ed25519 signature from the Auditor
  * 0x0002 for [bincode serialisation ↗](https://github.com/bincode-org/bincode/blob/trunk/docs/spec.md) E25519 serialisation by the Auditor

The `log_directory` field is optional. If set, Cloudflare will use it to fetch audit proofs and validate them.

This API is authenticated via [mTLS ↗](https://www.cloudflare.com/learning/access-management/what-is-mutual-tls/).

```sh
curl 'https://plexi.key-transparency.cloudflare.com/namespaces' \
          --header 'Content-Type: application/json' \
          --data '{
   "name": "your.new.log.com",
   "root": "1/1111111111111111111111111111111111111111111111111111111111111111",
   "log_directory": "https://your.new.log.com/path/to/proofs",
  "signature_version": 1
  }'
{
  "name": "your.new.log.com",
  "log_directory": "https://your.new.log.com/path/to/proofs",
  "root": "1/1111111111111111111111111111111111111111111111111111111111111111",
  "status": "Initialization",
  "reports_uri": "/namespaces/your.new.log.com/reports",
  "audits_uri": "/namespaces/your.new.log.com/audits",
  "signature_version": 1
}
```

After publishing the first epoch, `status` will show `Online`. Possible statuses include:

* `Online`
* `Initialization`
* `Disabled`

## List all namespaces

Refer to the example below to get information about all public namespaces.

```sh
curl 'https://plexi.key-transparency.cloudflare.com/namespaces'
{
   "namespaces": [
       { "name": "your.new.log.com", "root": "1/abc", "reports_uri": "/namespaces/your.new.log.com/reports", "audits_uri": "/namespaces/your.new.log.com/audits", "log_directory": "https://your.new.log.com/path/to/proofs", "status": "online" },
       { "name": "my.new.log.com", "reports_uri": "/namespaces/meta-bt-2024/reports", "audits_uri": "/namespaces/meta-bt-2024/audits", "status": "initialization" }
   ]
}
```

## Disable a namespace

If a log state has been corrupted, lost, or needs to be sharded to be maintainable, the Auditor allows the Log operator to mark a namespace as `Disabled`.

This API is authenticated via [mTLS ↗](https://www.cloudflare.com/learning/access-management/what-is-mutual-tls/).

```sh
curl -X PATCH 'https://plexi.key-transparency.cloudflare.com/namespaces/{namespace}' \
          -H 'Content-Type: application/json' \
          -d '{
   "status": "Disabled"
  }'
{
  "name": "your.new.log.com",
  "log_directory": "https://your.new.log.com/path/to/proofs",
  "root": "1/1111111111111111111111111111111111111111111111111111111111111111",
  "status": "Disabled",
  "reports_uri": "/namespaces/your.new.log.com/reports",
  "audits_uri": "/namespaces/your.new.log.com/audits",
  "signature_version": 1
}
```
