# Comment replies / 评论回复

Get bounded replies for one Facebook comment using its expansion token.

使用展开令牌获取 Facebook 评论回复。

Task / 任务: `facebook_get_comment_replies_v1`
Platform / 平台: Facebook / Facebook
Billing / 计费: 60 Credits per successful task / 每个成功任务 60 Credits

## Facebook directory chain / Facebook 目录链路

Chain: profile path → `profile_id` → post `post_id` → comment `comment_id` plus `expansion_token`. The post ID used by the comments and replies tasks must be decimal ASCII digits; use `comment_id`, not `legacy_comment_id`, for replies. The provider OpenAPI leaves nested `data` untyped, so the fields below are the bounded Asklear projection. The live reply probe returned an empty page; replies always publish `next_cursor: null`.
链路：主页路径 → `profile_id` → 帖子 `post_id` → 评论 `comment_id` 加 `expansion_token`。评论和回复任务使用的帖子 ID 必须是 ASCII 十进制数字；回复要使用 `comment_id`，不要使用 `legacy_comment_id`。供应商 OpenAPI 对嵌套 `data` 未定义类型，下面字段是 Asklear 的有界投影。实时回复探测返回空页；回复任务始终发布 `next_cursor: null`。
Estimate / 估价: call `estimate_collection`; start directly when `approval_required=false`, otherwise obtain approval for `upper_bound_credits`.
估价：调用 `estimate_collection`；`approval_required=false` 时直接启动，否则请用户确认 `upper_bound_credits`。

## Limitations / 限制

- One fixed marketplace data route is called per task; no automatic version fallback or cross-platform fan-out is performed.
- Returned data is bounded and projected into task-specific public fields; missing fields are not inferred.
- Each successful request is charged once by the configured Asklear task price.
- The provider OpenAPI leaves nested data untyped; this task publishes only the bounded Asklear projection documented here.
- Use the decimal ASCII post_id returned by profile posts for comments and replies; use comment_id rather than legacy_comment_id for replies.
- Comment reactions_count accepts an integer or ASCII decimal string and is normalized to a nonnegative integer.
- Reply results currently have no public cursor and always publish next_cursor as null; the live reply probe was empty.
- Production exposure requires the configured marketplace data connection and bounded live acceptance evidence.
