Combos (e.g. vip, mycodex) auto-fallback through multiple providers.

OpenAI format

curl -X POST $FLOW_ROUTER_URL/v1/chat/completions \
  -H "Authorization: Bearer $FLOW_ROUTER_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-haiku-4-5",
    "messages": [{"role":"user","content":"Say hi"}],
    "stream": false
  }'

Set "stream": true to receive SSE chunks (delta format).

Anthropic format

curl -X POST $FLOW_ROUTER_URL/v1/messages \
  -H "Authorization: Bearer $FLOW_ROUTER_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-haiku-4-5",
    "max_tokens": 1024,
    "messages": [{"role":"user","content":"Say hi"}]
  }'

Token saver (RTK)

When RtkTokenSaver is enabled in settings, tool-result messages over 4 KB are auto-compressed by format (git diff, build output, grep, tree, etc.) before being forwarded upstream — typical 40-80% reduction for agent loops.
