What it is

ByteDance's crawler, associated with training data collection for Doubao and related models. Repeatedly reported by CDNs and site operators as the highest-volume AI crawler on the web and as inconsistent about robots.txt.

What blocking it costs you

Little to lose. If you want it gone, expect to block by user-agent at the edge rather than to ask politely in robots.txt.

Ask this page a question, with one GET

A question about this page, answered by a call you can make right now — no key, no account, no JSON-RPC, nothing to assemble. The query string is already filled in with this page's own subject.

Every parameter above is a value the endpoint reads, not an address it visits: nothing is fetched on your behalf. Called without any parameter, each endpoint returns its own specification instead of an error. All of them.
