Messages

Use POST /v1/messages for Anthropic-compatible clients such as Claude Code and Anthropic SDKs.

curl https://anyroute.io/v1/messages \
  -H "Authorization: Bearer YOUR_ANYROUTE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-3-5-haiku-20241022",
    "max_tokens": 128,
    "messages": [{"role": "user", "content": "Hello"}]
  }'

Group behavior:

• Anthropic group: forwards as Anthropic Messages.
• OpenAI group: converts Anthropic Messages to OpenAI Responses.
• Gemini group: converts Anthropic Messages to Gemini native requests.

Use this endpoint when the client expects an Anthropic-compatible API.
