模型
查询生成记录
按生成 ID 查询一次调用的费用、用量与延迟；记录在调用完成后几秒内可查，此前返回 404，稍后重试即可。
先调用「对话」，从响应头 X-Praxis-Generation-Id 取得 id，替换 gen_123。
GET
/model/v1/generation● 支持请求参数
idstring必填◐ 部分支持query: Generation ID from the X-Praxis-Generation-Id response header of the model request.
使用 /model 响应头 X-Praxis-Generation-Id；响应体 id 和 X-Request-Id 不能查询，返回 404。
返回
200
鉴权、限流、参数校验等平台错误按 problem+json 返回；OCR 的错误也为 problem+json，其它模型调用的错误按该端点所属格式（OpenAI 或 Anthropic）返回，参见 错误码
响应
HTTP 200
