Questions
How much does the Xiaohongshu search suggestions API cost?
One call costs $0.02 and returns one page of about 10 results. Collecting 1,000 results takes about 100 calls, $2.00 in total. Each page is a separate call; failed calls are not charged.
How do I get the next page?
Pass page.next_cursor from the response back as the cursor parameter. When page.has_more is false there is nothing left. Every page is its own call at $0.02.
Do I need a Xiaohongshu (RedNote) account, cookies or a QR login?
No. You send only your okdata API key. The data is public data from Xiaohongshu (RedNote); nothing is fetched with your own Xiaohongshu (RedNote) account.
Am I charged when a call fails?
No. Every error response says charged: false, except a timeout, which says charged: null until the outcome is known. Resend with the same Idempotency-Key and you are never charged twice.
What if Xiaohongshu (RedNote) does not show a field?
The field is null, and meta.unavailable names it with the reason: platform (the platform never shows it) or capability (we cannot fetch it yet).
