Getting Deepgram .net SDK working with a local deepgram instance

[brian-merton-max]

Hi

I would appreciate any help or tips on how to get the latest .net sdk: https://github.com/deepgram/deepgram-dotnet-sdk working with a local deepgram instance we have running.

We are currently using a vanilla httpclient to send transcription requests from call recordings to the self hosted instance, however as part of making sure we're staying up to date with the latest changes and also having tighter coupling, we're looking to change the code to use the sdk.

I can happily use the sdk to send call recordings to the cloud version fine, but everytime I try to use the CreateListenRESTClient class I'm getting Deepgram API Key is invalid, even though this is the same key we're using with the vanilla httpclient.

Any help, greatly appreciated

Thanks

Brian

It looks like we're missing some important information to help debug your issue. Would you mind providing us with the following details in a reply?

• The deepgram product you are using (e.g Speech to Text, Agent API)
• A request ID that triggered your error or issue.

This relates to the Speech to Text product and specifically: https://github.com/deepgram/deepgram-dotnet-sdk/blob/main/Deepgram/Clients/Listen/v1/REST/Client.cs

Hi @brian-merton-max, it sounds like you are using Deepgram self-hosted, is that right? If so, please see our doc section on using the .NET SDK with self-hosted.

API keys are not actually used by self-hosted deployments at the request level (only as authorization to bring up the deployment), but the SDKs have certain structures that still need to be abided by.

If that doesn't work, please share the full error that the .NET SDK is raising for you, and I'll investigate further.

Thanks for replying, I've reviewed the documents and everything seems to be inline with the link you posted.

try { var apiKey = _config["DeepgramLocal:Token"]; var apiUrl = _config["DeepgramLocal:URL"]; var options = new DeepgramHttpClientOptions() { BaseAddress = apiUrl }; var deepgramClient = ClientFactory.CreateListenRESTClient(apiKey, options); using (var memoryStream = new MemoryStream()) { await audioFile.CopyToAsync(memoryStream); { CancellationTokenSource cancelToken = new CancellationTokenSource(600000); var response = await deepgramClient.TranscribeFile( memoryStream, new PreRecordedSchema() { Model = "nova-2", DetectEntities = true, Diarize = true, }, cancelToken); if (response == null) { return BadRequest("No response from Deepgram"); } else { return Ok(response); } } } } catch (Exception ex) { return BadRequest(ex.Message); }
When this code run it throws the Deepgram API Key is invalid when setting up the DeepgramHttpClientOptions, I've checked the url and it matches what we use when we call the url via a http client.

Any help greatly appreciated
