Cloudflare Browser Run v2026-08-31：/crawl 接口新增
Browser Run - Crawl endpoint now respects the Content Signals `use` directive
The /crawl endpoint now respects the use directive of the Content Signals ↗ standard, letting site owners express the maximum level at which their content may be used.
/crawl 端点现在遵循 Content Signals ↗ 标准的 use 指令，允许网站所有者声明其内容可被使用的最高级别。
You can declare your intended level with the new contentUse parameter. Allowed values, from least to most permissive, are reference and full, and the default is full. If a target site's robots.txt sets a use level that is more restrictive than your declared contentUse, the crawl request is rejected with a 400 error.
你可以使用新的 contentUse 参数来声明你预期的级别。允许的取值从宽松到严格依次为 reference 和 full，默认值为 full。如果目标网站的 robots.txt 设置的 use 级别比你声明的 contentUse 更严格，则爬取请求将被拒绝并返回 400 错误。
