Warning

This integration method is maintained but no longer actively developed. For the best experience and latest features, use our new AI Gateway with unified API access to 100+ models.

You can follow their documentation here: https://api-docs.deepseek.com/

Gateway Integration#

Create a Helicone account

Log into helicone or create an account. Once you have an account, you can generate an API key.

Create a DeepSeek AI account

Log into platform.deepseek.ai or create an account. Once you have an account, you can generate an API key from your dashboard.

Set HELICONE_API_KEY and DEEPSEEK_API_KEY as environment variable

HELICONE_API_KEY=<your API key>DEEPSEEK_API_KEY=<your API key>

Modify the base URL and add Auth headers

Replace the following DeepSeek AI URL with the Helicone Gateway URL:

https://api.deepseek.ai/v1/chat/completions -> https://deepseek.helicone.ai/v1/chat/completions

and then add the following authentication headers:

Authorization: Bearer <your API key>

Now you can access all the models on DeepSeek AI with a simple fetch call:

Example#

curl --request POST \      --url https://deepseek.helicone.ai/chat/completions \      --header 'Content-Type: application/json' \      --header "Authorization: Bearer $DEEPSEEK_API_KEY" \      --header "Helicone-Auth: Bearer $HELICONE_API_KEY" \      --data '{          "model": "deepseek-chat",          "messages": [              {                  "role": "system",                  "content": "Say Hello!"              }          ],          "temperature": 1,          "max_tokens": 30        }'
