Your Own Keys (BYOK)

Subscribe to the byok plan, add provider keys, and call namespaced models through the same OpenAI SDK base URL.

Setup

Subscribe to the byok plan from /app/plans (price shown there and on /pricing).
Add OpenAI, Anthropic, and/or Gemini keys at /app/provider-keys (validated before save; encrypted at rest).
Create a Zenith Cloud API key on the dashboard.
List models with your Bearer key — only that account’s discovered models are returned.

Model IDs

BYOK model ids are namespaced: openai/…, anthropic/…, gemini/…. Hosted catalog ids such as auto are for wallet-metered hosted plans.

Example

Terminal

curl -sS "$ZENITH_CLOUD_URL/api/v1/chat/completions" \
  -H "Authorization: Bearer $ZENITH_CLOUD_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "openai/gpt-4o",
    "messages": [{"role": "user", "content": "Hello"}]
  }'
