# Quickstart

Go from an API key to a live approval checkpoint and a content scan in a few minutes. You'll need a workspace API key — [create one in the dashboard](/getting-started/authentication.md).

{% hint style="info" %}
Every example reads the key from the `MAETRA_API_KEY` environment variable. Set it once:

```bash
export MAETRA_API_KEY="maetra_xxxxxxxxxxxxxxxxxxxx"
```

{% endhint %}

### 1. Verify your key

Confirm the key works and see what it's allowed to do:

{% tabs %}
{% tab title="cURL" %}

```bash
curl "https://api.maetra.io/v1/ping" \
  -H "Authorization: Bearer $MAETRA_API_KEY"
```

{% endtab %}

{% tab title="JavaScript" %}

```javascript
const res = await fetch("https://api.maetra.io/v1/ping", {
  method: "GET",
  headers: {
    Authorization: `Bearer ${process.env.MAETRA_API_KEY}`,
  },
});
if (!res.ok) throw new Error(`Maetra API ${res.status}`);
const data = await res.json();
console.log(data);
```

{% endtab %}

{% tab title="TypeScript" %}

```typescript
const res = await fetch("https://api.maetra.io/v1/ping", {
  method: "GET",
  headers: {
    Authorization: `Bearer ${process.env.MAETRA_API_KEY}`,
  },
});
if (!res.ok) throw new Error(`Maetra API ${res.status}`);
const data = (await res.json());
```

{% endtab %}

{% tab title="Python" %}

```python
import os, requests

res = requests.get(
    "https://api.maetra.io/v1/ping",
    headers={"Authorization": f"Bearer {os.environ['MAETRA_API_KEY']}"},
)
res.raise_for_status()
print(res.json())
```

{% endtab %}

{% tab title="Rust" %}

```rust
use serde_json::json;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let key = std::env::var("MAETRA_API_KEY")?;
    let client = reqwest::Client::new();
    let res = client
        .get("https://api.maetra.io/v1/ping")
        .bearer_auth(&key)
        .send()
        .await?;
    let data: serde_json::Value = res.json().await?;
    println!("{data:#}");
    Ok(())
}
```

{% endtab %}

{% tab title="C++" %}

```cpp
#include <curl/curl.h>
#include <cstdlib>
#include <string>

int main() {
    CURL* curl = curl_easy_init();
    std::string auth = "Authorization: Bearer " + std::string(std::getenv("MAETRA_API_KEY"));
    struct curl_slist* headers = nullptr;
    headers = curl_slist_append(headers, auth.c_str());
    curl_easy_setopt(curl, CURLOPT_URL, "https://api.maetra.io/v1/ping");
    curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
    curl_easy_perform(curl);   // response is written to stdout by default
    curl_slist_free_all(headers);
    curl_easy_cleanup(curl);
    return 0;
}
```

{% endtab %}

{% tab title="Java" %}

```java
import java.net.URI;
import java.net.http.*;

var client = HttpClient.newHttpClient();
var request = HttpRequest.newBuilder()
    .uri(URI.create("https://api.maetra.io/v1/ping"))
    .header("Authorization", "Bearer " + System.getenv("MAETRA_API_KEY"))
    .method("GET", HttpRequest.BodyPublishers.noBody())
    .build();
var response = client.send(request, HttpResponse.BodyHandlers.ofString());
System.out.println(response.body());
```

{% endtab %}
{% endtabs %}

```json
{
  "ok": true,
  "workspace_id": "ws_3Nf9k2",
  "scopes": ["govern:checkpoints:write", "secure:scan:write"]
}
```

The `scopes` array lists exactly what this key can do.

### 2. Request approval for an action (Govern)

Ask Maetra to evaluate a sensitive action. The response is **synchronous** — a fast-path policy may decide immediately; otherwise you get a `pending` checkpoint to poll.

{% tabs %}
{% tab title="cURL" %}

```bash
curl -X POST "https://api.maetra.io/v1/checkpoints" \

  -d '{

{% hint style="info" %}
Notice we passed **`agent_name`**, not `agent_id` — this agent isn't registered in Maetra, and that's fine. If it *were* registered, you'd pass its `agent_id` instead (or both). See [Agents](/agents.md).
{% endhint %}

### 3. Wait for the decision

If `status` is `pending`, long-poll for the human decision. The request holds open up to \~50s; reconnect if it returns `202` with no change.

Proceed **only** when `status` is `approved`. The `decision_token` is signed proof you can verify offline — see [Decision tokens](/govern-api/decision-tokens.md).

### 4. Scan content (Secure)

Independently, screen any prompt, tool call, or output before acting on it:

Honor `recommended_action`: `block` → stop, `flag` → allow but log/review, `log` → allow.
