Post schema
The unified SocialCrawl post schema. Every field, its type, per-platform availability, and a machine-readable JSON Schema, generated from the canonical Zod source.
Every SocialCrawl endpoint that returns a post gives you this exact shape, whatever the source platform. Write your parser once and the same code reads post data from every platform below. That is the unified schema: one contract instead of a dozen raw upstream formats.
Field reference
| Field | Type | Nullable | Description |
|---|---|---|---|
id | string | No | Platform-specific post ID (always a string; numeric upstream IDs are stringified) |
url | string | Yes | Direct URL to the post on the source platform |
content.text | string | Yes | Post caption, description, or text content |
content.media_urls | string or string[] | Yes | URL(s) of the primary media. Single string for video/photo posts; array of strings for carousels. |
content.thumbnail_url | string | Yes | URL to thumbnail image |
content.duration_seconds | integer | Yes | Video/clip duration in seconds (null for non-video posts) |
author.username | string | Yes | Author username |
author.display_name | string | Yes | Author display name |
author.avatar_url | string | Yes | URL to author profile picture |
author.verified | boolean | Yes | Whether the author account is verified |
engagement.views | integer | Yes | View count (if available). For Instagram video/reels this is the play count: the headline 'Views' the IG app shows. Instagram removed per-post play counts from its public web pages in August 2026, so GET /v1/instagram/post now fills the count automatically from a second source within the same call: videos and reels keep a numeric views with no extra endpoint or workaround. Note: since mid-July 2026 Instagram's play count is Instagram-only. It no longer includes Facebook crosspost views (Meta-side change; the app UI changed identically). For combined reach, also fetch the Facebook crosspost via /v1/facebook/post. |
engagement.likes | integer | Yes | Like / reaction count |
engagement.comments | integer | Yes | Comment count. Note: on GET /v1/instagram/post this is Instagram's edge_media_to_parent_comment.count (top-level comments); the IG list endpoints report the mobile comment_count total (includes replies). Both land on this same field. |
engagement.shares | integer | Yes | Share / repost / retweet count. On Instagram this is reshare_count (the paper-plane Share / Send count) and it exists only on Instagram's mobile surface, so it is returned by /v1/instagram/post/stats, /v1/instagram/profile/reels/full, and /v1/instagram/profile/posts/full. The web-sourced Instagram list and search endpoints return null (never fabricated). |
engagement.saves | integer | Yes | Save / bookmark count. null on Instagram: the save count is platform-private and Instagram exposes no numeric save metric on any surface (never fabricated). |
flags.nsfw | boolean | Yes | NSFW flag (null when platform does not surface) |
flags.spoiler | boolean | Yes | Spoiler flag (null when platform does not surface) |
flags.pinned | boolean | Yes | Pinned-to-profile flag (null when platform does not surface) |
flags.deleted | boolean | No | Whether the post is tombstoned (always present) |
flags.likes_hidden | boolean | Yes | Present and true when the creator has hidden the like count. engagement.likes is null in that case (never the platform's decoy preview number). Absent on normal posts. |
flags.comments_hidden | boolean | Yes | Present and true when the upstream reports the comment count as hidden. engagement.comments is null in that case. Absent on normal posts. |
flags.shares_hidden | boolean | Yes | |
flags.views_hidden | boolean | Yes | |
flags.saves_hidden | boolean | Yes | |
published_at | string or integer | Yes | Post creation timestamp as an ISO 8601 UTC string. When the upstream sent a Unix epoch it is converted here and the raw epoch is preserved under post.ext.published_at_epoch for one deprecation cycle. |
Extension fields (ext)
Platform-specific passthrough. Each field is present only on the platforms that expose it and is absent everywhere else, so treat every ext.* field as optional. These carry the richer, per-platform signals the unified leaves cannot hold, and the join keys that chain endpoints together.
| Field | Type | Nullable | Description |
|---|---|---|---|
ext.music_id | string | Yes | TikTok music/clip id (exact string): pass to /v1/tiktok/song/videos?clipId= to find videos using the same sound |
ext.author_id | string | Yes | The creator's platform-native numeric user id. On TikTok search and list items, pass to /v1/tiktok/profile?user_id= for the creator's current follower count (survives username changes). On Instagram search/reels items it is present on every row from every serving source, accepted by /v1/instagram/basic-profile?userId=. On Facebook it appears when the upstream exposed a numeric actor id and no real handle. |
ext.author_followers | integer | Yes | The creator's follower count as embedded in the search payload itself, when the search source happens to carry one. On Instagram search/reels it is null on a plain call, because Instagram stopped sending follower counts in its search payload in August 2026; send include=creator (or country) and it is filled from the creator's profile, 2 credits per creator looked up. It stays null when that lookup does not resolve. |
ext.author_following | integer | Yes | |
ext.author_posts_count | integer | Yes | |
ext.author_country | string | Yes | The creator's country as they declare it on Instagram's About this account panel, as a country name (for example Spain). It is not where the reel was filmed. Present only on /v1/instagram/search/reels when the request sends include=creator (or country), filled by looking the creator up. Null when Instagram does not publish a country for the creator or the lookup did not resolve, and nothing is guessed; absent on a plain call. |
ext.author_public_email | string | Yes | The public contact email on the creator's profile. Present only on /v1/instagram/search/reels when the request sends include=creator, filled by looking the creator up. Null when the creator lists no public email or the lookup did not resolve; absent on a plain call. |
ext.author_public_phone | string | Yes | The public contact phone number on the creator's profile. Present only on /v1/instagram/search/reels when the request sends include=creator, filled by looking the creator up. Null when the creator lists no public phone or the lookup did not resolve; absent on a plain call. |
ext.download_count | integer | Yes | How many times the video has been saved to a device. TikTok only, and distinct from engagement.saves: a save keeps the video in a private collection on the platform, a download takes a copy off it, and TikTok counts the two separately. Present on TikTok post, search and post-list responses; absent everywhere else. |
ext.region | string | Yes | TikTok only: the country TikTok registers the video to, as an ISO 3166-1 alpha-2 code (normally the creator's account country when they posted). It is not the viewer's country, not the region you requested, and not a language. On /v1/tiktok/trending, /v1/tiktok/search and /v1/tiktok/search/top it is how you tell which rows are from a given country: filter on it when you need only that country. The region request parameter still only sets the proxy. |
ext.subreddit | string | Yes | Reddit subreddit name (search/list items): pass to /v1/reddit/subreddit/details?subreddit= |
ext.title | string | Yes | |
ext.selftext | string | Yes | |
ext.upvote_ratio | integer | Yes | Reddit only: the share of a post's votes that are upvotes, as a fraction from 0 to 1 and usually close to 1 (six live rows measured 1, 1, 1, 0.86, 0.75, 1). Fractional despite the integer type this schema emits for every numeric leaf, the same caveat as author.ext.average_rating. Populated on /v1/reddit/search rows whose source carries it, and null everywhere else on Reddit including /v1/reddit/post and /v1/reddit/subreddit. |
ext.flair | string | Yes | |
ext.content_language | string | Yes | The language the platform itself tags the post with, when it sends one: Reddit's own language tag on Reddit lanes, and TikTok's caption-language tag (for example de) on /v1/tiktok/trending?feed=local. Null when the platform could not tell (Reddit und, TikTok un, common on short or emoji-only captions); absent where the source sends no tag. Never inferred from the text by us: that is post.computed.language. |
ext.type | string | Yes | |
ext.content_type | string | Yes | |
ext.ticker_symbols | string[] | Yes | |
ext.video_view_count | integer | Yes | Instagram's legacy 3-second-view count. Historical: Instagram stopped serving it in August 2026 (removed from its web post surface along with the web play count), so fresh /v1/instagram/post lookups no longer carry it and no source can restore it. Use engagement.views (the play count) instead. |
ext.ig_play_count | integer | Yes | Instagram-only play count (ig_play_count). Since mid-July 2026 Instagram's headline play count (engagement.views) no longer includes Facebook crosspost views and equals this value; it is surfaced explicitly so you can tell the Instagram-only figure apart and detect any future re-divergence. For combined Instagram + Facebook reach, also fetch the Facebook crosspost via /v1/facebook/post. Present on /v1/instagram/post/stats and, since the August 2026 views fix, on /v1/instagram/post for video posts. |
ext.repost_count | integer | Yes | |
ext.media_type | string | Yes | |
ext.text_truncated | boolean | Yes | |
ext.ip_location | string | Yes | |
ext.carousel_count | integer | Yes | |
ext.remix_count | integer | Yes | |
ext.audio_cluster_id | string | Yes | Instagram's audio cluster for a reel, as an exact digit string: the id Instagram uses to group different uploads of the same sound. Present on /v1/instagram/audio/reels rows and on /v1/instagram/profile/reels with include=stats; absent on a row when it is not available and on every other surface. |
ext.facebook_likes | integer | Yes | Instagram only: the Facebook cross-post share that was EXCLUDED from engagement.likes on this row. A post shared to Facebook arrives from some sources with its Facebook likes already folded into the Instagram count, so the share is subtracted and published here, which keeps engagement.likes the Instagram-only figure instagram.com shows on the post. Add the two together for the combined number. Absent when the read carried no Facebook share, and absent on a post whose owner hides the like count, because nothing can be subtracted from a null. A response that excluded a share also carries a note in data._warnings. |
ext.facebook_comments | integer | Yes | Instagram only: the Facebook cross-post share that was EXCLUDED from engagement.comments on this row, the comment counterpart of post.ext.facebook_likes. Each leaf appears only for the count it actually changed, so a post whose likes are hidden but whose comments were reconciled carries this one alone. |
ext.published_at_epoch | integer | Yes | Raw Unix epoch for published_at (seconds, or milliseconds when the upstream sent millis). Present only when the upstream sent a numeric epoch that was normalised to the ISO 8601 published_at string. Kept for one deprecation cycle for integrations pinned to the numeric form. |
ext.usertags | string[] | Yes | |
ext.coauthors | string[] | Yes | Instagram collaborative posts (the native "Collab" feature). The full list of co-author accounts on the post, as { id, username, full_name, is_verified, profile_pic_url }. A collab post has ONE producer and appears in every co-author's grid, so post.author is whichever account created it, which is not necessarily the profile you queried. The complete set of accounts on a post is post.author.username plus every username in this array. An empty array means Instagram reports the post as NOT a collab; the field is absent on surfaces that carry no co-author signal, including /v1/instagram/post (its web source ships the field permanently empty, so use /v1/instagram/post/stats for a single post). |
ext.music | string | Yes | |
ext.sponsor_tags | string[] | Yes | |
ext.location | string | Yes | |
ext.quoted_post | string | Yes | Threads quote posts: the post this one quotes, as { id, url, author: { id, username }, text, media_urls, thumbnail_url }. A quote post usually carries no caption or media of its own, and the text and video you see on the post's page belong to this attachment, by a different author. It is returned here rather than merged into post.content, so content.* always stays the outer post's own content and one account's media is never attributed to another. Absent on posts that are not quote posts. |
ext.retweeted_post | string | Yes | |
ext.quote_count | integer | Yes | |
ext.all_media_urls | string[] | Yes | |
ext.reaction_counts | string[] | Yes | |
ext.share_urn | string | Yes | |

ext.amazon_shop_trending_picks | string[] | Yes | |
ext.amazon_shop_curations | string[] | Yes | |
ext.amazon_shop_socials | string[] | Yes | |
ext.ad | string | Yes | Ad Library envelope (Facebook adlibrary/ad and adlibrary/company/ads items): page_id, currency, spend, reach_estimate, publisher_platforms, categories, targeted_or_reached_countries, cta_text, cta_type, link_url, is_active, end_date_iso, display_format, title, video_hd_url, video_sd_url. Absent on every non-ad surface. |
ext.apple_music | string | Yes | |
ext.feedback_id | string | Yes | |
ext.event | string | Yes | |
ext.trend | string | Yes | Trend-board envelope: what TikTok's own trend board says about the row. On /v1/tiktok/hashtags/popular: rank, country_code, period_days, posts and views for the window (not lifetime totals), industry / industry_id / industry_label for the first board the hashtag was read from (null for the overall board), boards listing EVERY board it ranks on as { industry, industry_id, industry_label, rank } in board order (so a hashtag in the top 3 overall and on an industry board shows both), popularity_curve as { date, value } with value 0 to 100 relative to the window's peak, and top_creators. On /v1/tiktok/videos/popular: rank, country_code, period_days, order_by, period_views, organic_views, engagement_rate, six_second_view_through_rate, content_tags. Absent on every non-board surface. |
ext.updated_at | string | Yes |
Platform availability
27 platforms return the Post shape. id, flags.deleted are never null on any platform. The fields below vary: yes means the platform populates it (the value may still be null); a blank means the platform never provides it, so it is always null.
