Lists a repository's branches, the default first, with prefix
search. The repository must be one the caller may see — the same set
GET /v1/provider/github/repos lists — or it is 404.

## Request

5 fields.

| Field   | In    | Type    | Required | Description                                                         |

| `q`     | query | string  | —        | Q keeps branches whose name starts with it, matched by GitHub.      |
| `limit` | query | integer | —        | Limit is the page size: 1 to 100, and 50 when absent or unreadable. |
| `after` | query | string  | —        | After is the `next` of the previous page.                           |

| `branches`           | body | provider.githubBranch\[] | —      | Branches is this page: the default branch first, then the rest by name.                                      |
| `branches[].commit`  | body | string                   | —      | Commit is the sha the branch points at.                                                                      |

| `total`              | body | integer (int64)          | —      | Total is how many branches match q, across every page.                                                       |

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

## Examples

**CLI**

`hanzo` has no subcommand for this operation — the CLI serves only what cloud's live route table confirms. Use HTTP or an SDK.

**SDK**

**.ts**

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

const api = new ProviderApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.getProviderGithubReposByOwnerByRepoBranches({ owner: 'owner', repo: 'repo' });
```

**.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).get_provider_github_repos_by_owner_by_repo_branches(owner='owner', repo='repo')
```

**.go**

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

resp, _, err := client.ProviderAPI.GetProviderGithubReposByOwnerByRepoBranches(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::get_provider_github_repos_by_owner_by_repo_branches(&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).getProviderGithubReposByOwnerByRepoBranches();
```

**HTTP**

```bash
curl https://api.hanzo.ai/v1/provider/github/repos/<owner>/<repo>/branches \
  -H "Authorization: Bearer $HANZO_API_KEY"
```

**MCP**

MCP reaches **provider** through the `provider` tool, which names its 38 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"
         }
       }
     }'
```
