## Paging and failures

- One call returns the first page only, up to 20 items, with no cursor, for 12 credits.
- A call that runs and finds nothing is a successful call: status is "empty", items is empty, and it costs 12 credits.
- On this call Xiaohongshu cannot tell a note that does not exist from one with no data: both come back as empty, and both are charged.
- 1 call per second per key, 5 after a purchase; going over is not charged. [Rate limits](https://socialtoai.com/docs/credits-and-billing.md#rate-limits)
- A failed call costs 0 credits and is never retried on its own. [Error codes](https://socialtoai.com/docs/api/errors.md)

## FAQ

**Do I need a Xiaohongshu account or Xiaohongshu's own API access?**

No. You only need a SocialToAI key. The call returns content and account information publicly visible on Xiaohongshu; you never sign in to Xiaohongshu or apply for anything there.

**Can I get the next page?**

No. On Xiaohongshu this interface gives its first page only (up to 20 items): the response carries no cursor, and page.has_more is always false.

**What does “Preview” mean here?**

Preview: this interface is not marked stable yet, so its parameters and fields may still change. It is charged like any other call, and a failed call is not charged.
