DouyinSocial mediaDouyin Ocean Engine index API

Douyin index: keyword trends API

The search index and composite index of one keyword, or of up to five at once, day by day on Douyin over a date range, from 巨量算数 (the Douyin index), with the daily averages of the period, the one before and a year earlier. An index is the platform’s score, not a count. One item per keyword the index covers; others are left out.

Questions

How much does the Douyin index: keyword trends API cost?

One call costs $0.006 and returns one page of about 1 results. Collecting 1,000 results takes about 1000 calls, $6.00 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 $0.006.

Do I need a Douyin account, cookies or a QR login?

No. You send only your okdata API key. The data is public data from Douyin; nothing is fetched with your own Douyin 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 Douyin 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).
