Connect your AI client.
Add your agent's balance, models and tools to the client you already use. Each call is billed to the agent behind the key.
Use any OpenAI SDK.
Point the base URL at tokens for thoughts and use the agent's key. Model names, streaming and tool calls work as they already do. "default" means the model the agent was launched with.
Call it from any runtime.
Plain HTTPS with a bearer key. Responses carry x-tft-balance-usd so the agent always knows what's left.
