| **Address**   | `https://api.hanzo.ai/v1/event/timeseries` |
| **Method**    | `GET`                                      |
| **Operation** | `get_event_timeseries`                     |
| **Auth**      | `Authorization: Bearer $HANZO_API_KEY`     |

Returns the caller org's LLM usage over time as an evenly-spaced series.
One point per hour or per day — the bucket the window implies, 24h giving hours and
7d/30d giving days — carrying requests, total tokens and spend in cents. Empty
buckets are filled with zeros so a client charts a continuous line.

The org is the validated principal's — never a parameter. 401 without a validated
bearer, 400 on an unknown range, 503 when the warehouse is unreachable.

## Request

3 fields.

| Field   | In    | Type   | Required | Description                                                                                                   |
| ------- | ----- | ------ | -------- | ------------------------------------------------------------------------------------------------------------- |
| `range` | query | string | —        | Range is a relative window: a count and a unit — 24h, 7d, 90d, any \<N>h or \<N>d — or day, week, month, all. |
| `start` | query | string | —        | Start is the inclusive lower bound of a custom window, RFC3339.                                               |
| `end`   | query | string | —        | End is the exclusive upper bound of a custom window, RFC3339.                                                 |

## Response

| Status    | Body             | Meaning |
| --------- | ---------------- | ------- |
| `200`     | event.Timeseries | ok      |
| `default` | problem-details  | refused |

`200` body — 12 fields.

| Field                 | In   | Type                | Always | Description                                                                                        |
| --------------------- | ---- | ------------------- | ------ | -------------------------------------------------------------------------------------------------- |
| `end`                 | body | string              | —      | End is the window's exclusive upper bound, RFC3339 UTC.                                            |
| `interval`            | body | string              | —      | Interval is the bucket width: hour or day.                                                         |
| `range`               | body | string              | —      | Range is the window that was actually applied: 24h, 7d, 30d or custom.                             |
| `scope`               | body | event.Scope         | —      |                                                                                                    |
| `scope.org`           | body | string              | —      | Org is the IAM org slug the rows were read under: the validated principal's, resolved server-side. |
| `series`              | body | event.UsagePoint\[] | —      | Series is one point per bucket, oldest first, with empty buckets zero-filled.                      |
| `series[].requests`   | body | integer (int64)     | —      | Requests is how many LLM calls fell in this bucket.                                                |
| `series[].spendCents` | body | integer (int64)     | —      | SpendCents is what they cost, in cents.                                                            |
| `series[].t`          | body | string              | —      | T is the bucket's start, RFC3339 UTC, aligned to the interval.                                     |
| `series[].tokens`     | body | integer (int64)     | —      | Tokens is prompt plus completion tokens over those calls.                                          |
| `source`              | body | string              | —      | Source is the warehouse table the series read.                                                     |
| `start`               | body | string              | —      | Start is the window's inclusive lower bound, RFC3339 UTC.                                          |

Failure carries the platform error shape — see [Errors](https://docs.hanzo.ai/docs/errors).

## Examples

**CLI**

```bash
hanzo event timeseries
```

**SDK**

**.ts**

```ts
import { Configuration, EventApi } from 'hanzoai';

const api = new EventApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.getEventTimeseries();
```

**.py**

```python
from hanzoai.cloud import ApiClient, Configuration
from hanzoai.cloud.api import EventApi

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = EventApi(client).get_event_timeseries()
```

**.go**

```go
cfg := hanzoai.NewConfiguration()
cfg.AddDefaultHeader("Authorization", "Bearer "+os.Getenv("HANZO_API_KEY"))
client := hanzoai.NewAPIClient(cfg)

resp, _, err := client.EventAPI.GetEventTimeseries(context.Background()).Execute()
if err != nil {
	return err
}
```

**.rs**

```rust
use hanzo_client::apis::{configuration::Configuration, event_api};

let mut cfg = Configuration::new();
cfg.bearer_access_token = std::env::var("HANZO_API_KEY").ok();

let result = event_api::get_event_timeseries(&cfg, Default::default()).await?;
```

**.java**

```java
import ai.hanzo.cloud.ApiClient;
import ai.hanzo.cloud.api.EventApi;

ApiClient client = new ApiClient();
client.setBearerToken(System.getenv("HANZO_API_KEY"));

var result = new EventApi(client).getEventTimeseries();
```

**HTTP**

```bash
curl https://api.hanzo.ai/v1/event/timeseries \
  -H "Authorization: Bearer $HANZO_API_KEY"
```

**MCP**

MCP reaches **event** through the `event` tool, which names its 9 operations with its own verbs — this one among them, under a name only MCP declares. `describe` explains any of them:

```bash
curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,
       "method": "tools/call",
       "params": {
         "name": "describe",
         "arguments": {
           "op": "get_event_economic"
         }
       }
     }'
```
