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://docs.perplexity.ai/

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 Perplexity AI account

Log into Perplexity AI or create an account. Once you have an account, you can generate an API key from your dashboard.

Set HELICONE_API_KEY and PERPLEXITY_API_KEY as environment variable

HELICONE_API_KEY=<your API key>PERPLEXITY_API_KEY=<your API key>

Modify the base URL and add Auth headers

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

https://api.perplexity.ai/chat/completions -> https://perplexity.helicone.ai/chat/completions

and then add the following authentication headers:

Authorization: Bearer <your API key>

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

Example#

curl --request POST \  --url https://perplexity.helicone.ai/chat/completions \  --header "Authorization: Bearer $PERPLEXITY_API_KEY" \  --header "Helicone-Auth: Bearer $HELICONE_API_KEY" \  --header "Content-Type: application/json" \  --data '{    "model": "sonar-pro",    "messages": [{"role": "user", "content": "Say this is a test"}]}'
