# Geo Nodes API

In order to interact with Geo node endpoints, you need to authenticate yourself
as an admin.

## Retrieve configuration about all Geo nodes

```
GET /geo_nodes
```

```bash
curl --header "PRIVATE-TOKEN: 9koXpg98eAheJpvBs5tK" https://gitlab.example.com/api/v4/geo_nodes
```

Example response:

```json
[
  {
    "id": 1,
    "url": "https://primary.example.com/",
    "primary": true,
    "enabled": true,
    "current": true,
    "files_max_capacity": 10,
    "repos_max_capacity": 25,

```

## Retrieve configuration about a specific Geo node

```
GET /geo_nodes/:id
```

```bash
curl --header "PRIVATE-TOKEN: 9koXpg98eAheJpvBs5tK" https://gitlab.example.com/api/v4/geo_nodes/1

Please note that the `health_status` parameter can only be in an "Healthy" or "Unhealthy" state, while the `health` parameter can be empty, "Healthy", or contain the actual error message.

## Retrieve project sync or verification failures that occurred on the current node

This only works on a secondary node.

```
GET /geo_nodes/current/failures
```

| Attribute | Type | Required | Description |
| --------- | ---- | -------- | ----------- |
| `type`         | string  | no | Type of failed objects (`repository`/`wiki`) |
| `failure_type` | string | no | Type of failures (`sync`/`checksum_mismatch`/`verification`) |

This endpoint uses [Pagination](README.md#pagination).
