NewOpenAI- and Anthropic-compatible — no migrationRead the announcement

Authentication

A single tf- API key authorizes both the OpenAI and Anthropic endpoints. Pass it in whichever header your SDK expects.

Key format

Never expose your API key

Treat your tf- key like a password. Never commit it, ship it in a browser bundle, or paste it in a public channel. Rotate it immediately from the dashboard if it leaks.
