> Use this file to discover all available pages before exploring further.

> ## Agent Instructions
> Use Stable documentation by default. Honor an explicit Beta request or a URL under /docs/beta/. If the requested version conflicts with the installed CLI package or API origin, clarify the target before writing integration code.
> Pages under /docs/beta/ document Beta; other product pages document Stable. Keep the CLI package, commands, API origin, and credentials within the selected version. State the documentation version in your answer.
> For MCP search, always pass version: Stable or version: Beta. Unfiltered search mixes both versions. For filesystem reads, keep Beta queries under /beta/ and exclude /beta/ from Stable queries; discover paths before reading them.
> The public docs base is https://photon.codes/docs. Convert MCP page paths to public URLs under that base, preserving /beta/ when present. Read https://photon.codes/docs/skill.md for version selection and https://photon.codes/docs/llms.txt for the version indexes.

# List project subscriptions

> List project subscriptions: listProjectSubscriptions in the TypeScript, Python, Rust and Go clients.

`GET /v1/projects/{projectId}/billing/subscriptions`

Lists the plan each of the selected project's categories holds, with its price and the payer's standing. It suits showing a project's plan wherever projects are listed; the billing overview adds billing periods, fixed charges, entitlements and usage.

```typescript TypeScript theme={null}
photon.projects.billing.listProjectSubscriptions(input: ListProjectSubscriptionsInput, options?: RequestOptions): Promise<ListProjectSubscriptionsOutput>
```

**Python**

```python Python theme={null}
photon.projects.billing.list_project_subscriptions(input: ListProjectSubscriptionsInput) -> models.ListProjectSubscriptionsResponse
```

**Rust**

```rust Rust theme={null}
client.list_project_subscriptions(project_id: String).await -> Result<ResponseValue<types::ListProjectSubscriptionsResponse>, Error<ListProjectSubscriptionsError>>
```

**Go**

```go Go theme={null}
client.Projects.Billing.ListProjectSubscriptions(ctx context.Context, params *ListProjectSubscriptionsParams, opts ...RequestOption) (*ListProjectSubscriptionsResponse, error)
```

```typescript TypeScript theme={null}

  path: {
    projectId: "projectId",
  },

        },
    })
)
```

```rust Rust theme={null}

    .credential("accountServiceKey", Credential::Bearer(SecretString::from(token)))
    .build()?;
let result = client
    .list_project_subscriptions("projectId".to_owned())
    .await
    .map_err(|error| format!("{error:?}"))?
    .into_inner();
```

```go Go theme={null}
import (
	"context"
	"os"

	photonapi "github.com/photon-hq/api/packages/go"
)

ctx := context.Background()
client := photonapi.NewClient(photonapi.WithAPIKey(os.Getenv("PHOTON_API_TOKEN")))
result, err := client.Projects.Billing.ListProjectSubscriptions(ctx, &photonapi.ListProjectSubscriptionsParams{
