Frequently Asked Questions

Answers regarding deployment, security limits, and key renewal

When static system context, codebase snippets, or multi-turn chat histories are cached, subsequent calls read directly from memory. This cuts input token processing overhead by up to 80% while dramatically reducing latency.

Yes. You only need to set the base URL parameter in your Python or TypeScript SDK client to our secured proxy address and pass your provisioned Keycrops authorization token.

The entry plan supports up to 1,200 requests per minute and 1.5M tokens per minute with burst smoothing across distributed regional clusters, preventing unexpected throttling.

All traffic is routed through encrypted TLS 1.3 channels under a strict zero data retention policy. Neither prompt inputs nor generated completions are recorded to disk or utilized for training.
