| **Address**   | `https://api.hanzo.ai/v1/provider/{provider}/choose` |
| **Method**    | `POST`                                               |
| **Operation** | `post_provider_by_provider_choose`                   |
| **Auth**      | `Authorization: Bearer $HANZO_API_KEY`               |

The form the chooser page posts: `state` (the token the page was given), and either `account` (one of the accounts it offered) or `install` (go on to the provider's install page). It binds the chosen account to the organization that started the connect and redirects back to the page that asked, as the callback does.

It is public and carries no principal. Its authority is the token alone: signed like the callback's state, carrying the offered accounts under its signature, and single-use, so a page answers once and only with an account it offered.

## Request

1 field.

| Field      | In   | Type   | Required | Description |

| `provider` | path | string | yes      |             |

## 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 provider choose <provider>
```

**SDK**

**.ts**

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

const api = new ProviderApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.postProviderByProviderChoose({ provider: 'provider' });
```

**.py**

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

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = ProviderApi(client).post_provider_by_provider_choose(provider='provider')
```

**.go**

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

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

**.rs**

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

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

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

**.java**

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

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

var result = new ProviderApi(client).postProviderByProviderChoose();
```

The method above is the one at the current release of the document. `hanzoai@8.5.914` (npm) and `hanzoai@8.5.914` (PyPI) were generated from an earlier release, where this operation carried a different id, so it spells the method differently — regenerating the clients is what makes the two agree.

**HTTP**

```bash
curl -X POST https://api.hanzo.ai/v1/provider/<provider>/choose \
  -H "Authorization: Bearer $HANZO_API_KEY"
```

**MCP**

MCP reaches **provider** through the `provider` tool, which names its 41 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": "list_connections"
         }
       }
     }'
```
