Real responses are complete. ## One schema on 2 platforms. The [response reference](https://socialtap.dev/docs/reference/instagram/topic/index.md#response) lists every field, its type and when it is `null`. [See the full schema](https://socialtap.dev/resources/topic/index.md). - ### Null means unknown A field Instagram doesn't show is null, never zero or an empty string, so a real zero always means zero. - ### What it accepts An Instagram topic page link (instagram.com/popular/harry-potter/), a hashtag link (instagram.com/explore/tags/cooking/, which opens its topic page for signed-out visitors), a keyword search link (instagram.com/explore/search/keyword/?q=harry%20potter), or the topic's words (harry potter). - ### Write one parser Instagram and Pinterest answer in these fields, so the code that reads one reads them all. - **`platform`string**: Platform ID (instagram, tiktok, …). - **`id`string**: Platform-native topic ID; on platforms whose topic pages are keyed by their words (Instagram), the words lowercased and joined by hyphens (harry-potter). - **`name`string**: The topic's title as its page shows it (Harry Potter); null when the source does not show it. - **`url`string**: Canonical topic page URL. - **`description`string**: The platform's summary of the topic, as plain text with paragraph breaks (on Instagram, superscript markers ¹, ² cite platform_specific.instagram.source_urls by position). Null when the page has none. - **`related_searches`string\[\]**: Related searches the platform suggests for the topic, in its order; each is a topic of its own (pass it as url). \[\] when none. - **`approximate_fields`string\[\]**: JSON paths of values rounded by the platform or parsed from display text ("189M reels": platform_specific.instagram.post_count). \[\] when all exact. - **`unknown_fields`string\[\]**: JSON paths of lists whose \[\] means unknown rather than none (a source that cannot see them); null already means unknown for every other field. \[\] when every list is known.

A keyword without one is answered from Instagram's search when that has a summary, related searches or reels (name and reel count then null), and returns not_found when it has none. - The reel count is rounded as Instagram shows it and listed in approximate_fields. Rarer topics and categories show none. - Broad topics are Instagram categories (platform_specific.instagram.is_category), pages made of narrower topics, without a reel count. ## 1 credit per request.
