Gateway Integration

1

Create a Helicone account

Log into helicone or create an account. Once you have an account, you can generate an API key.
2

Create an FireworksAI account

Log into www.fireworks.ai or create an account. Once you have an account, you can generate an API key.
3

Set HELICONE_API_KEY and FIREWORKS_API_KEY as environment variable

HELICONE_API_KEY=<your API key>
FIREWORKS_API_KEY=<your API key>
4

Modify the base URL and add Auth headers

Replace the following FireworksAI URL with the Helicone Gateway URL:https://api.fireworks.ai/inference/v1/chat/completions -> https://fireworks.helicone.ai/inference/v1/chat/completionsand then add the following authentication headers.
Helicone-Auth: `Bearer ${HELICONE_API_KEY}`
Authorization: `Bearer ${FIREWORKS_API_KEY}`
Now you can access all the models on FireworksAI with a simple fetch call:

​
Example

curl --request POST \
  --url https://fireworks.helicone.ai/inference/v1/completions \
  --header "Authorization: Bearer $FIREWORKS_API_KEY" \
  --header "Helicone-Auth: Bearer $HELICONE_API_KEY" \
  --header "Content-Type: application/json" \
  --data '{
    "model": "accounts/fireworks/models/llama-v3-8b-instruct",
    "prompt": "Say this is a test"
}'
