Authentication

Your worker connects to the Zero Runtime runtime over a secure connection. Configure the connection and credentials with environment variables.

Connect to the runtime

Point the worker at your runtime address:

export ZRT_RUNTIME_ADDRESS=us1.rt.zeroruntime.ai:443

Authenticate the worker

Get your auth token, or your API key and secret, from the Zero Runtime dashboard. Then authenticate in one of two ways: use a JWT auth token, or provide an API key and secret and let the SDK mint a JWT for you.

# Option 1: JWT auth token
export ZRT_AUTH_TOKEN=<token>

# Option 2: API key + secret (the SDK mints a JWT)
export ZRT_API_KEY=<key>
export ZRT_SECRET_KEY=<secret>

Provider keys

Set the key for each provider your pipeline uses:

export DEEPGRAM_API_KEY=<key>    # speech-to-text
export GOOGLE_API_KEY=<key>      # LLM
export CARTESIA_API_KEY=<key>    # text-to-speech
