public System.Threading.Tasks.Task<bool> IsPinnedAsync(string cid, System.Threading.CancellationToken cancellationToken=default(System.Threading.CancellationToken));
```

#### Parameters

<a name="ResQ.Storage.PinataClient.IsPinnedAsync(string,System.Threading.CancellationToken).cid" />

`cid` [System.String](https://learn.microsoft.com/en-us/dotnet/api/system.string "System.String")

Cancellation token for the operation.

Implements [IsPinnedAsync(string, CancellationToken)](./ResQ.Storage.IStorageClient.IsPinnedAsync\(string,System.Threading.CancellationToken\).md "ResQ.Storage.IStorageClient.IsPinnedAsync(string, System.Threading.CancellationToken)")

#### Returns

[System.Threading.Tasks.Task\<](https://learn.microsoft.com/en-us/dotnet/api/system.threading.tasks.task-1 "System.Threading.Tasks.Task`1")[System.Boolean](https://learn.microsoft.com/en-us/dotnet/api/system.boolean "System.Boolean")[>](https://learn.microsoft.com/en-us/dotnet/api/system.threading.tasks.task-1 "System.Threading.Tasks.Task`1")\

```csharp theme={null}
bool isPinned = await storage.IsPinnedAsync("Qmabc123...");
if (!isPinned)

### Remarks

A pinned CID is guaranteed to remain available on the IPFS network.
Unpinned content may be garbage collected by IPFS nodes.
