POST /v1/messages/count_tokens

要求

curl https://api.model-gate.com/v1/messages/count_tokens \
  -H "x-api-key: mg_live_..." \
  -H "anthropic-version: 2023-06-01" \
  -H "content-type: application/json" \
  -d '{
    "model": "ch-46s",
    "messages": [{"role": "user", "content": "Count these tokens."}]
  }'

回复

{
  "input_tokens": 9
}

别名的解析完全与 /v1/messages。此端点不消耗 API 密钥 RPM 计数器，但仍会验证身份验证和模型可用性。

错误

  "error": {
    "type": "invalid_request_error",
    "code": "model_not_found",
    "message": "Unknown or disabled model: unknown-model"
