Long arrays and strings are shortened here. Real responses are complete.

## One schema on 6 platforms.

The [response reference](https://socialtap.dev/docs/reference/x/search_hashtags/index.md#response) lists every field, its type and when it is `null`. [See the full schema](https://socialtap.dev/resources/web_result/index.md).

- ### Null means unknown

  A field X doesn't show is null, never zero or an empty string, so a real zero always means zero.
- ### What it accepts

  Words to find X hashtags by, as a web search reads them: a topic, a niche, a name (cooking, bitcoin, "machine learning", 料理).
- ### Write one parser

  X, TikTok, Instagram and 3 more platforms answer in these fields, so the code that reads one reads them all.

- **`platform`string**: Platform the item is on.
- **`type`string**: The kind of item the result names, as the resource that describes it: profile (an account), post, hashtag, sound, place or community. The item's summary is the field of that name, and a filled result's record is details.\<type>. A search that finds several kinds (a platform's top search) mixes them in one list. New values may be added as more kinds are searchable; treat unknown values as other.
- **`position`integer**: Zero-based rank of the result in the list, across pages: the search engine's order, counting only the results kept.
- **`url`string**: The item's canonical link on the platform (the account's page for a profile, the post's for a post).
- **`matched_url`string**: The page the index listed: the item's own page, or one of its pages that names it (a video of an account, for a profile found through it).
- **`title`string**: The page's title as the index shows it: often the item's name, but not the item's own field. Null when the index shows none.
- **`snippet`string**: The index's excerpt of the page: often the item's description and counts as the page stated them when it was indexed, days or weeks ago. Null when the index shows none.
- **`profile`object**: The account the result names (type profile): what its link and the index's text say of it, completed from details when the result is filled. Null for every other type.

## What teams build with the X (Twitter) Hashtag Search API.

- ### Find the hashtags around a niche
- ### Discover a hashtag's spellings and variants
- ### Turn a keyword into hashtags to track
- ### Pick tags for a campaign

## Good to know before you build.

- X has no logged-out search, so results come from a web search engine's index of X's hashtag pages, in the engine's order.
- A tag is listed when its page is indexed and its name or page holds your words: bitcoin also finds BitcoinCash, and a tag can come up because a post quoted on its page uses the word.
- There is no fill=true, because X has no logged-out hashtag lookup.
- The index goes only so deep, so a search usually ends after a few pages (page.end_reason end).
- Case doesn't matter, and the query's own site: operators are removed.

## 1 credit per page. Failed requests are free.

Buy credits once and spend them on any endpoint, on any platform.

## Questions about the X (Twitter) Hashtag Search API.

More in the [API reference](https://socialtap.dev/docs/reference/x/search_hashtags/index.md).

**Does it return how many posts use a hashtag?**

No. X shows no count, description or picture for a hashtag logged out, so those fields are null and each result has the tag's name and link.

**How much does the X (Twitter) Hashtag Search API cost?**

A page of up to 50 hashtags costs 1 credit. Every successful page is charged, empty pages included. SocialTap credits cost $0.75–$1.97 per 1,000, depending on the plan or pack.

**How do I get the next page?**

Repeat the same request with cursor set to page.next_cursor from the previous response, keeping the other parameters. When page.has_more is false there are no more pages. Cursors expire after 24 hours.
