Xiaohongshu (RedNote) Trending API: paging and billing.

One call returns a page of up to 20 items. When page.has_more is true, send page.cursor back as cursor for the next page; each page costs 12 credits and a cursor works for 30 minutes.
A call that runs and finds nothing is a successful call: status is "empty", items is empty, and it costs 12 credits.

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 Xiaohongshu (RedNote) Trending API.
