Anthropic Messages — drop in your slug
Stav speaks the Anthropic Messages API. Point the Anthropic SDK at base_url="https://api.stav.ai/v1" and your existing code keeps working — including cache_control markers and thinking mode, which pass through to Anthropic verbatim. Set STAV_API_KEY and the curl below works.
bash
curl https://api.stav.ai/v1/messages \
-H "Authorization: Bearer $STAV_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "claude-sonnet-4-6",
"max_tokens": 256,
"messages": [{"role": "user", "content": "Hello!"}]
}'Already using the OpenAI SDK? The same model is reachable at — drop in the slug above as the field and it works.
