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 Nebius Token Factory account

Log into Nebius Token Factory or create an account. Once you have an account, you can generate an API key from your dashboard.

Set HELICONE_API_KEY and NEBIUS_API_KEY as environment variable

HELICONE_API_KEY=<your API key>NEBIUS_API_KEY=<your API key>

Modify the base URL and add Auth headers

Replace the following Nebius Token Factory URL with the Helicone Gateway URL:

https://api.tokenfactory.nebius.com -> https://nebius.helicone.ai

and then add the following authentication headers:

Authorization: Bearer <your API key>

Now you can access all the models on Nebius Token Factory with a simple fetch call:
