API Changelog

Stories in Collaborations (Discovery API): Stories are now available to all API customers. Within a brand collaboration, you can filter posts by type, including story_original and story_reshared.

Post classification (feed_type): Optional feed_type on Collaborations posts (Instagram: feed | reels; null elsewhere). Combine with type for full post classification.

Followers growth filter (AI Search): followersGrowthRate is now supported on the /ai/* endpoints for Instagram, TikTok, and YouTube. Takes an interval (i1month–i6months) plus min and/or max as a decimal fraction (0.05 = 5%); at least one bound required. Text search and lookalikes profiles return followersGrowthRate (defaults to i6months), omitted when no rate is available.

Reports: recentPosts[].thumbnail is now returned for all platforms (previously, YouTube only). Appears gradually, with full coverage after ~30 days due to report caching.

Search: query can no longer be combined with username. Requests doing so return: "Username filter and other filters cannot be used together. Please use only one of them."

Instagram Reports: recentPosts[].id, popularPosts[].id, and sponsoredPosts[].id now return the Instagram post ID instead of an internal ID (e.g. 3769455982611575129_173560420 → DRPzD6oCLFZ).

List filters for AI Search (Discovery API): Include or exclude your own influencer lists directly in AI Search across Instagram, TikTok, and YouTube.

Bio & captions filters: Now accept up to 10 phrases; a profile matches if at least one phrase matches.

YouTube AI Search: Responses now expose the YouTube video title on matched posts.

Full-text bio & captions filters (AI Search): Filter on exact text in a creator's bio or captions. On YouTube, the caption filter searches title and description, so the filter is named keywords.

Multi-creator Lookalikes: Specify 1–5 source users and get lookalikes that blend the traits of all of them (previously one user only). Includes minor parameter renaming to reflect the change.

TikTok Media Download (Raw API) is deprecated in favor of TikTok Media Download URL. The old endpoint had video size limitations and returned the video file directly; the new endpoint returns a download URL that expires 24 hours after the request.

Hashtags & mentions filters (AI Search): Include and exclude specific hashtags and @mentions, plus new dictionary endpoints for popular tags and mentions. Mentions are not supported on YouTube (the filter is skipped for that platform).

Average views filter (AI Search): Filter creators by average views using mean or median, across Instagram, TikTok, and YouTube.

Both filters are live with no integration changes required and work alongside existing AI Search filters.

Legacy Collaborations endpoints removed. Following the August 2025 Collaborations overhaul and full customer migration, the old endpoints have been taken out of service.

brand_id: Now returned across collaborations, sponsored posts, reports, and brand dictionary responses. Sponsor accounts belonging to the same brand share a brand_id; use the Brand Dictionary endpoint to retrieve all associated accounts.

API status page: status.modash.io is live, powered by the public /health endpoint, with Slack, email, and RSS subscriptions. Raw API status is not covered yet.

Collaboration & sponsored posts data quality: More accurate sponsored post detection with fewer false positives, plus richer collaboration data.

Creator Lookalikes (Discovery API): Find creators similar to a given creator by content style, same-platform or cross-platform.

TikTok AI text search upgraded: Now generates a holistic creator description by synthesizing content themes, captions, posting patterns, and creator identity, matching the Instagram and YouTube behavior. No endpoint changes, no migration; image search unchanged.

AI Search now bills per result, not per request. Each result costs 0.025 credits (the default 6 results still cost 0.15 credits). Up to 50 results can now be retrieved in a single request. Applies to Lookalikes, too.

Collaborations Posts: two new fields (Instagram, TikTok, YouTube):

Sponsor coverage: Significant improvements to sponsor detection across all supported platforms.

Error handling (/collaborations/posts, /collaborations/summary): When a matched account has no identified collaboration posts, the API now returns 404 posts_not_found instead of a 500. This distinguishes it from account_not_found, and these requests are non-billable.

Sponsorship classification (label): Collaboration posts now indicate how a collaboration was identified:

Sponsor username: New field returns the brand's direct handle automatically.

Precision time filtering: Filter collaboration posts by specific time intervals via postCreationTimestampMs.

AI Search v2 (Instagram, then YouTube): Text-based AI search now analyses creator identity holistically (bio, captions, content themes, posting patterns) rather than matching individual posts. Default for all Discovery API users, with no code changes and no impact on billing or credit usage. TikTok followed in March 2026.

Larger collaboration index: Instagram +32%, TikTok +37%, YouTube +100% identified sponsored content.

Rate limiting: Rate limiting now includes a burst budget, so short bursts above your per-second limit are processed instead of rejected.

YouTube AI Search (Discovery API): Text-based AI Search is now available for YouTube, covering 3.3M YouTube creators.

New AI Search filters:

Index update: TikTok AI Search expanded to 17.7M searchable accounts; Instagram to 12.2M.

Sort by relevance: Search results can be sorted by audienceRelevance (IG, TT, YT).

Match explanations: Lookalikes responses now include a match object explaining why an influencer was returned (IG, TT).

Instagram subdivisions: Subdivision support added to Instagram Reports (similar to City in Location) for deeper geographic granularity.

Docs (YouTube Raw API): duration and comments on video info marked optional, since they are unavailable in some cases (e.g. "Premieres in X time" videos).

TikTok AI Search (Discovery API): Both text-based and image-based search endpoints are now available.

Collaborations Grouping: Added groupBrandCollaborations boolean field. When true, this allows retrieval of brand-level insights across all platforms.

Discovery API Data Quality:

YouTube Raw API: Added members_only_content error return to indicate if content is locked behind channel memberships.

AI Search Live (Discovery API):

Collaborations API Overhaul:

YouTube: Video Subtitles endpoint now available.

Instagram: Profile Address details added to User Info response.

Calculation Method: Select median or average (mean) for metrics like ER%, likes, comments, and shares.

Audience Relevance: New switch in Influencer filters to toggle between finding lookalikes by Audience or Topics (Content).

Calculation Method: Now supports median or average.

Stats by Content Type: Returns average metrics by platform-specific types (e.g., Reels, Shorts, Videos). Note: Optimized for performance over /performance-data.

Hashtags: Added support for TikTok and YouTube.

Health: Now shows status for all major endpoints.
