      "text": "一直认为写作是件很耗费体力与脑力的事情，特别是从新构架一个新的世界，一个文明。这需要你有丰富的尝试与思考，过去，我们从来不缺少天马行空的想象力，但是少有一个如刘慈欣般有着历史、物理学与哲学思考的作者。所以从这个角度来讲，三体的出现对中国科幻界绝对是幸事。霍金之前曾经警告过我们，如果有外星人，他们对地球也是恶意的。那时我不懂，在读完这本书时我回想自己小时候拍打小虫子时的情景。或许，在更高级别的文明里，你我只不过是虫子。",

Response fields

Business data is in results. The table lists the fields a record can contain; values the source does not provide are never made up.

Errors and billing

401

Missing or invalid key. Authentication runs before parameter checks, so unauthenticated requests never see the parameter schema.

422

Wrong parameter name or value. The error lists the parameters and allowed values this capability accepts and the closest match; it happens before any charge.

402

Insufficient balance. Top up first.

429

Per-minute request limit reached. Wait for Retry-After and try again.

503

Could not complete right now. Any charge for the call goes back to your balance automatically, and the billing receipt in the response states the actual outcome, including when it is not yet known. Do not resend blindly.

200 empty

The request completed without data and is not charged (billing.reason = empty_result_refunded).

• Douban Movies: Long Reviews, Short Reviews, and Visibility Limits ↗

  Douban Movies explains movie reviews and short reviews separately, noting that the short review section does not show all short reviews and that collapsed content has differing public visibility. Movie review lists returned by this endpoint should not be taken as a complete history or all audience opinions; this source does not replace separate rules for books or music.
