# Hashtag posts API 4 endpoints on 4 platforms return the same Post object. The posts under a hashtag or topic. A call costs from $0.0020 to $0.0200, each endpoint at its own price; a failed call is free. ## Hashtag posts on each platform | Platform | Endpoint | Path | A page | Returns | Price | | --- | --- | --- | --- | --- | --- | | Douyin | [Douyin hashtag videos](https://dataxapi.com/apis/douyin/hashtags/videos/list.md) | `GET /v1/douyin/hashtags/videos/list` | 10 | Post list | $0.0020 / call | | Instagram | [Instagram hashtag posts](https://dataxapi.com/apis/instagram/hashtags/posts/list.md) | `GET /v1/instagram/hashtags/posts/list` | 35 | Post list | $0.0020 / call | | TikTok | [TikTok hashtag videos](https://dataxapi.com/apis/tiktok/hashtags/videos/list.md) | `GET /v1/tiktok/hashtags/videos/list` | 20 | Post list | $0.0020 / call | | Xiaohongshu (RedNote) | [Xiaohongshu topic notes](https://dataxapi.com/apis/xiaohongshu/topics/notes/list.md) | `GET /v1/xiaohongshu/topics/notes/list` | 10 | Post list | $0.0200 / call | Prices are the prices in force. A call that fails, or whose result is uncertain, costs nothing. ## The Post object Every endpoint above returns these fields, with the same names and types. | Field | Type | Description | | --- | --- | --- | | `id` | text | ID; pass it unchanged to the get endpoint | | `url` | link | Link that opens the post | | `type` | text | Content format | | `title` | text | Title | | `text` | text | Body text | | `lang` | text | Language of the text | | `published_at` | time | When it was published | | `author.id` | text | Author's account ID | | `author.username` | text | Author's handle | | `author.name` | text | Author's display name | | `author.avatar_url` | link | Author's avatar | | `author.verified` | yes/no | Whether the author is verified | | `author.followers` | integer | Author's follower count | | `metrics.likes` | integer | Likes | | `metrics.comments` | integer | Comments | | `metrics.shares` | integer | Shares | | `metrics.favorites` | integer | Saves | | `metrics.views` | integer | Views | | `metrics.reposts` | integer | Reposts | | `images` | list of link | Image addresses | | `hashtags` | list of text | Hashtags, without the # | | `mentions[].id` | text | Account ID | | `mentions[].username` | text | Handle | | `mentions[].name` | text | Display name | | `is_pinned` | yes/no | Whether the author pinned it | | `post_id` | text | ID of the thread's root post when this is a reply; otherwise null | | `parent_id` | text | ID of the item it replies to directly; otherwise null | | `root_id` | text | ID of the first-level reply its thread hangs under | [The object's own page →](https://dataxapi.com/docs/objects/post/) ### Which platform fills which field A field an endpoint cannot give is listed in `meta.unavailable` on every answer, so a gap is never a surprise. | Platform | `title` | `lang` | `author.username` | `author.name` | `author.avatar_url` | `author.verified` | `author.followers` | `metrics.shares` | `metrics.favorites` | `metrics.views` | `metrics.reposts` | `images` | `hashtags` | `mentions[].id` | `mentions[].username` | `mentions[].name` | `is_pinned` | `post_id` | `parent_id` | `root_id` | | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | | Douyin | available | available | available | available | available | not available | not available | available | available | not available | not available | available | available | not available | not available | not available | not available | not available | not available | not available | | Instagram | not available | not available | not available | not available | not available | not available | not available | not available | not available | not available | not available | available | not available | not available | not available | not available | not available | not available | not available | not available | | TikTok | not available | available | available | available | available | not available | not available | available | available | available | not available | not available | available | available | not available | not available | not available | not available | not available | not available | | Xiaohongshu (RedNote) | available | not available | not available | available | available | not available | not available | available | available | not available | not available | available | available | available | not available | available | not available | not available | not available | not available | ## The same call on two platforms Same parameter names, same paging, same answer.

Names, text and IDs are examples, and so are the links: none is the recorded one (the page shows no one's personal data); the figures are as recorded. Long lists are cut. The request ID, cursor and balance are made up. ```jsonc { "code": "ok", "request_id": "356aeb4a-4d28-4a5a-9d78-511caeafab1e", "data": { "items": [ { "id": "7963545807100437923", "url": "https://www.douyin.com/video/7963545807100437923", "type": "video", "title": null, "text": "周末的周末露营日常，随手记录一下", "lang": "zh", "published_at": "2026-10-12T07:11:10.000Z", "author": { "id": "MS4wLjABAAAABGZA0lkiz3H7A-lxzB5Grql28u6Ykbup22O6ze_0pro", "username": "orange_soda22", "name": "橘子汽水不加冰", "avatar_url": "https://p3-pc.douyinpic.com/aweme/100x100/aweme-avatar/tos-cn-avt-0015_9aa5b7cd5493d4d36c71.jpeg" }, "metrics": { "likes": 11911, "comments": 190, "shares": 131, "favorites": 1081 }, "images": null, "hashtags": [ "周末去哪儿", "户外生活", // … 3 more ] }, // … 9 more ] }, "page": { "next_cursor": "c1.4Q5NqjU0XrkYdbZs6W7g4SY48XO9yirp7eO24Gqb", "cursor_expires_at": "2026-10-12T19:42:37.000Z", "has_more": true, "returned": 10 }, "warnings": [], "meta": { "capability": "douyin.hashtags.videos.list", "result_status": "complete", "fetched_at": "2026-10-12T18:42:37.000Z", "cached": false, "replayed": false, "unavailable": { "metrics.views": "capability", "metrics.reposts": "platform", "author.verified": "capability", "mentions": "capability", "post_id": "platform", "parent_id": "platform", "root_id": "platform", "author.followers": "capability", "is_pinned": "capability" }, "billing": { "amount": "0.002", "currency": "USD", "balance_after": "9.998" } } } ``` ## What comes back - [The Post object](https://dataxapi.com/docs/objects/post/): Fields 28, Endpoints that return it 81, Platforms 19 ## Questions about the Hashtag posts API ### How much does it cost? $0.0020 a call on Douyin, Instagram, TikTok; $0.0200 a call on Xiaohongshu (RedNote). You are charged when data comes back; a failed call costs nothing. No subscription, no monthly minimum. ### How do I get every page? Pass `page.next_cursor` back as `cursor` until `page.has_more` is false. Each page is one call at the same price. ### Does every platform fill every field? No. 20 of the 28 fields are missing on at least one platform; the table on this page says which. A field an endpoint cannot give is named in `meta.unavailable` on every answer, never filled with a guess. ### Do I need an account on the platform? No. One DataXAPI key reads all 4 platforms. No platform account and no cookie. ## Other data types [Comment replies API](https://dataxapi.com/roles/comments-replies-list/), [Trending topics API](https://dataxapi.com/roles/trends-list/), [Account profile API](https://dataxapi.com/roles/accounts-get/), [Account posts API](https://dataxapi.com/roles/accounts-posts-list/), [Comments API](https://dataxapi.com/roles/posts-comments-list/), [Post detail API](https://dataxapi.com/roles/posts-get/), [Post search API](https://dataxapi.com/roles/posts-search/), [Trending posts API](https://dataxapi.com/roles/posts-trending/), [Account search API](https://dataxapi.com/roles/accounts-search/), [Post metrics API](https://dataxapi.com/roles/posts-metrics/), [Community posts API](https://dataxapi.com/roles/communities-posts-list/), [Ad detail API](https://dataxapi.com/roles/ads-get/), [Advertiser ads API](https://dataxapi.com/roles/advertisers-ads-list/), [Advertiser search API](https://dataxapi.com/roles/advertisers-search/), [Ad library search API](https://dataxapi.com/roles/ads-search/), [Video transcript API](https://dataxapi.com/roles/transcripts-get/), [Followers API](https://dataxapi.com/roles/accounts-followers-list/), [Community profile API](https://dataxapi.com/roles/communities-get/), [Product detail API](https://dataxapi.com/roles/products-get/), [Product reviews API](https://dataxapi.com/roles/products-reviews-list/), [Product search API](https://dataxapi.com/roles/products-search/), [Creator search API](https://dataxapi.com/roles/creators-search/), [Creator profile API](https://dataxapi.com/roles/creators-get/), [Creator audience API](https://dataxapi.com/roles/creators-audience-get/), [Creator metrics API](https://dataxapi.com/roles/creators-metrics/), [Creator posts API](https://dataxapi.com/roles/creators-posts-list/), [All 21 platforms →](https://dataxapi.com/apis/) --- Last checked 2026-10-21 11:10 UTC.
