Overview

Use this guide to connect Claude Desktop to DeerAPI with an OpenAI-compatible base URL and a DeerAPI API Key. After configuration, Claude Desktop can call any model that is available on the live DeerAPI pricing page.

​
Prerequisites

  • A DeerAPI account.
  • A DeerAPI API Key.
  • The Claude Desktop application installed or accessible in your workspace.
  • A current model ID from the live pricing page.

​
Configure Claude Desktop

1

Open the provider settings

In Claude Desktop, open the settings area for custom OpenAI-compatible providers.
2

Set the base URL

Enter https://api.deerapi.com/v1 as the base URL. If the tool asks for a host without the version suffix, use https://api.deerapi.com.
3

Add the API Key

Paste your DeerAPI API key in the API key field.
4

Choose a model

Add or select a model ID from the live pricing page, then save the provider configuration.
5

Run a test request

Send a short prompt from Claude Desktop. A successful response confirms that the base URL, API Key, and model ID are configured correctly.

​
Troubleshooting

  • If the tool returns 401, create a new API Key and update the saved provider configuration.
  • If the tool returns 404, check whether the base URL expects /v1.
  • If the tool cannot find the model, verify the model ID on the live pricing page.
  • If requests fail intermittently, enable retries in the client or reduce parallel requests.
