| **Address**   | `https://api.hanzo.ai/v1/account/avatar` |
| **Method**    | `POST`                                   |
| **Operation** | `post_account_avatar`                    |
| **Auth**      | `Authorization: Bearer $HANZO_API_KEY`   |

Stores one image as the signed-in user's profile photo and answers the URL it is served from, which is also written to the user's IAM record — so every surface that already renders `avatar` picks it up with no further call.

The body is a multipart form with a `file` part. The format is decided by the BYTES, never the filename or the part's Content-Type: png, jpeg, gif and webp are accepted and everything else is refused with 415, so an SVG cannot be stored as a picture and later served as a program. Over 8 MiB is 413; empty is 400.

The photo is addressed by the sha256 of its bytes, so setting a new one yields a new URL rather than a stale cache of the old face. The caller is taken from the validated identity ONLY — there is no way to name a different subject — so this always sets your own photo, and a caller with no organization yet is refused.

## Request

The document declares no body for `POST /v1/account/avatar`. The handler is typed in cloud but its shape is not yet emitted, so the fields are not listed here — ask MCP's `describe` for `post_account_avatar`, which answers from the running route.

## Response

The document declares no response body for this operation. It answers `200` on success and the platform error shape on failure — see [Errors](https://docs.hanzo.ai/docs/errors).

## Examples

**CLI**

```bash
hanzo account avatar create
```

**SDK**

**.ts**

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

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

**.py**

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

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

**.go**

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

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

**.rs**

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

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

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

**.java**

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

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

var result = new AccountApi(client).postAccountAvatar();
```

**HTTP**

```bash
curl -X POST https://api.hanzo.ai/v1/account/avatar \
  -H "Authorization: Bearer $HANZO_API_KEY"
```

**MCP**

MCP reaches **account** through the `account` tool, which names its 6 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_account_appearance"
         }
       }
     }'
```
