author.usernameThe author's handle.metrics.repostsReposts.imagesImage addresses.hashtagsHashtags, without the #.is_pinnedWhether the author pinned it.
Compared with the Douyin Detail API, this call also gives author followers and views but does not give images or hashtags.
Every item also has platform, id, ref, approx and type; the response around the items is the same on every call. Response format
Bilibili Detail API: paging and billing.
5 calls per second per key, 20 after a purchase; going over is not charged. Rate limits
A failed call costs 0 credits and is never retried on its own. Error codes
“Last tested” above is the last day a real call of this interface succeeded. Each call reads from the platform, and fetched_at in the answer is when it was read. The same request sent again with the same key within 5 minutes is a replay (replayed: true): 0 credits, and the answer as first read.
Once connected over MCP, these questions use the Bilibili Detail API.
