# Official platform APIs vs third-party data APIs (2026)

> X, YouTube, TikTok, Douyin and WeChat each have an official API. What each one gives you, who can get access, its limits and price, and when a third-party data API fits better.

Canonical page: https://okdata.online/compare/official-apis-vs-data-apis/

Use the official API when you act on accounts you own or that have authorised you (posting, private analytics, your own followers) or when you need the platform's own terms; use a third-party data API for public data about accounts you do not control. The official X, YouTube, TikTok, Douyin and WeChat pages were read on 2026-11-12; on okdata a page of X search costs $0.002 and a page of Douyin search $0.02.

Every large platform has an official API, and for some jobs nothing else will do. But an official API is built around the platform's own idea of who should see what: usually the owner of an account, an app the user has authorised, or an approved researcher. A third-party data API is built around public data about any account. Which one you need depends on whose data it is and what you want to do with it.

## What to compare first

**Whose data it is.** Your own accounts, accounts that have logged in to your app and granted it access, or public posts and profiles of anyone. Official APIs are strongest on the first two.

**Read or write.** Posting, replying, managing comments and publishing articles are only possible through official routes. A data API reads.

**Who gets access.** Some official APIs are open to any developer with a card; others require an application, an approval or a business account.

**Limits and price.** Quotas per day, prices per resource, monthly caps. A free quota can be the cheapest option of all for small jobs.

**Terms and stability.** An official API comes with the platform's own terms and versioned documentation. That matters for compliance reviews and for products that must not break.

## Side by side

Facts come from each platform's own pages, read on 2026-11-12. The TikTok page did not load from our network that day, so the TikTok row cites the Wayback Machine copy of 2026-11-01.

| Platform | Official route | Who gets access | Public data about other accounts | Limits and price | okdata |
|---|---|---|---|---|---|
| X | X API, pay per use | Developers who buy credits in the Developer Console | Post and user reads, charged per resource returned | $5 per 1,000 posts read, $10 per 1,000 users read, $10 per 1,000 trends requests; 3 million post reads a month on pay-per-use; reads of your own data $1 per 1,000 | [X post search](https://okdata.online/apis/x/posts/search/): $0.002 a page of about 20, $0.10 per 1,000 posts |
| YouTube | YouTube Data API v3 | A Google Cloud project; some methods need OAuth | Search and video details yes; caption download only for videos you have permission to edit | By default 100 search.list calls a day, 100 uploads and 10,000 units for all other methods; a caption download costs 200 units | [YouTube video search](https://okdata.online/apis/youtube/videos/search/): $0.004 a page, billed per call rather than from a daily quota; transcripts of public videos with captions |
| TikTok | Research API | Approved researchers: academic institutions in the U.S., EEA, UK, Canada or Switzerland, not-for-profit research bodies in the EU, and Brazilian groups studying youth safety; independent of commercial interests | Public accounts and content, under the research terms | An application with a research proposal, ethics review and funding disclosure; an answer typically within 4 weeks; price not stated on the page | [TikTok video search](https://okdata.online/apis/tiktok/videos/search/): $0.002 a page of about 30 |
| Douyin | Douyin Open Platform | Apps that apply for each capability; user data needs that user's authorisation | Fan lists and fan data of users who authorised your app (fan list up to 5,000); a video search API (scope `aweme.dy.video_search`) for apps granted that capability | Per-capability approval; the search doc lists errors for an app without the capability and for used-up quota | [Douyin video search](https://okdata.online/apis/douyin/videos/search/): $0.02 a page of about 20 |
| WeChat Official Accounts | Official Account API | The account itself (access token from its AppID and AppSecret, called from a whitelisted server IP) or a third-party platform it authorised | Only the calling account's own published articles, 1 to 20 a call | Token valid for 7,200 seconds; price not stated on the pages read | [Official Account article history](https://okdata.online/apis/wechat_mp/accounts/articles/list/): any public account by its `gh_` ID, $0.02 for the 10 newest |

## Where okdata differs

- **Any public account, no authorisation.** You do not need the account owner to log in to your app, and you do not need to be an approved researcher. Douyin, Xiaohongshu and WeChat are reachable with the same key as X and YouTube.
- **One schema for five platforms and more.** An X post, a YouTube video and a Douyin video all come back as a post with `text`, `author`, `published_at` and `metrics`, so a cross-platform report is one loop.
- **No quota calendar.** You pay per call instead of waiting for a daily quota to reset. Failed calls and timeouts are free, and on most endpoints so is `not_found`.
- **Transcripts of other people's videos.** [YouTube transcripts](https://okdata.online/apis/youtube/videos/transcript/get/) cost $0.004 for any public video that has captions, which the official caption download does not allow unless you can edit the video.

## When okdata is the wrong choice

- **You want to write.** Posting on X, uploading to YouTube, publishing a WeChat article or managing comments needs the official API.
- **You want your own private numbers.** Your WeChat account's daily follower changes, your Douyin fans' age and region, your X bookmarks: the official API gives them to the account owner, and on X your own data costs $1 per 1,000 resources.
- **You are an eligible academic or not-for-profit researcher on TikTok.** The Research API gives you data under terms written for research, which an ethics board may prefer.
- **Your job is small and fits a free quota.** A few hundred YouTube video lookups a day fit inside the 10,000 free units.
- **A contract with the platform is required.** Some compliance reviews accept only data obtained directly from the platform.

[Official API vs third-party social data](https://okdata.online/answers/official-api-vs-third-party-social-data/) answers the short version of this question; [X API pricing](https://okdata.online/answers/x-api-pricing-2026/), [YouTube search quota exceeded](https://okdata.online/answers/youtube-search-quota-exceeded/), [TikTok Research API alternative](https://okdata.online/answers/tiktok-research-api-alternative/) and [Douyin Open Platform](https://okdata.online/answers/douyin-open-platform-api/) go deeper on single platforms.

## How to try it

Sign up for $0.10 of trial credit, no card needed, and follow the [quickstart](https://okdata.online/docs/quickstart/). The same search on two platforms differs only in the path:

```bash
curl -G "https://api.okdata.online/v1/x/posts/search" \
  -H "Authorization: Bearer $OKDATA_API_KEY" \
  --data-urlencode 'query=露营 lang:zh' \
  --data-urlencode 'sort=latest'

curl -G "https://api.okdata.online/v1/douyin/videos/search" \
  -H "Authorization: Bearer $OKDATA_API_KEY" \
  --data-urlencode 'query=露营'
```

Agents can do the same through the [MCP server](https://okdata.online/mcp/). Prices for every endpoint are on the [pricing page](https://okdata.online/pricing/).

## Questions

### Is third-party data less accurate than the official API?

Both read what the platform shows. Counts are taken at fetch time, so two reads minutes apart can differ. A count the platform hides comes back null on okdata and is named in `meta.unavailable`.

### Can I use both?

Yes. A common split: the official API for your own accounts and anything that writes, okdata for competitors, creators and keyword research across platforms.

### Does the Douyin Open Platform let me search videos?

Its OpenAPI list includes a video search API. The doc gives it the scope `aweme.dy.video_search`, has the app call it with a `client_token`, and lists errors for apps that have not been granted the capability and for quota that has run out. You apply for it as an app; okdata's Douyin search needs only a key.

### Can the WeChat API read another Official Account's articles?

The published-articles call works with the calling account's own token, or through a third-party platform that the account has authorised, and returns that account's own articles. For other accounts' public articles, use [Official Account article history](https://okdata.online/apis/wechat_mp/accounts/articles/list/); more on this in [ways to get WeChat Official Account data](https://okdata.online/compare/wechat-official-account-data-apis/).
