Authentication

How to authenticate with the API.

Get an API Key

1. Go to Settings → API Keys
2. Click Create API Key
3. Copy the key (starts with inf_)

Keep it Secret

• Don't commit to git
• Don't share publicly
• Use environment variables

1export INFERENCE_API_KEY="inf_your_key"

Browser apps? Never expose API keys in client-side code. Use a Server Proxy to keep credentials safe.

Using the Key

With SDKs

1from inferencesh import inference2import os34# Direct5client = inference(api_key="inf_your_key")67# From environment variable8client = inference(api_key=os.environ["INFERENCE_API_KEY"])

With REST API

1curl https://api.inference.sh/apps/run \2  -H "Authorization: Bearer inf_your_key" \3  -H "Content-Type: application/json" \4  -d '{"app": "infsh/echo", "input": {"message": "Hello!"}}'

Install SDKs

1pip install inferencesh23# With async support4pip install inferencesh[async]
