System Update
Released: 2026-04-06
We've just shipped a fix that implements this endpoint. It performs local token estimation, so it returns a valid {"input_tokens": N} response without any additional latency.
The endpoint supports:
- String and structured content block messages
- System prompts
- Tool definitions
The fix is resolved and on Live. Claud Code CLI should start normally against the Apertis API.
**Enjoy it.**
