Use Claude Messages when your application already follows Anthropic’s Messages API. Keep the request body format and replace the host, API key, and model ID.

Reference format: Claude Messages API. HiLinkup supports common request shapes; tools, images, caching, and other features depend on model availability.

“Claude Messages” is the protocol shape, not a requirement to use an overseas Claude model. Examples use the HiLinkup platform model aliyun/kimi-k3; confirm available IDs with /v1/models.

System prompt

Claude-style requests use a top-level system field instead of an OpenAI-style system message.

curl https://api.hilinkup.com/v1/messages \
  -H "content-type: application/json" \
  -H "x-api-key: $HILINKUP_API_KEY" \
  -H "anthropic-version: 2023-06-01" \
  -d '{
    "model": "aliyun/kimi-k3",
    "max_tokens": 1024,
    "system": "You are a concise integration assistant.",
    "messages": [
      {
        "role": "user",
        "content": "Give me a checklist for validating an API key."
      }
    ]
  }'
