Agent Skills
Ready-made research workflows your agent can load and run on the Captapi API. Each skill says which endpoints it calls, what the data can and cannot show, and where a person should check the result.
Every skill prints a credit estimate and asks before it spends. Failed calls are not billed.

ad-library-weekly-diff
Pulls each competitor's ads from the Meta, Google, LinkedIn and TikTok ad libraries, compares them with last week's snapshot, and reports new ads, stopped ads and new creative angles.
~11 credits per competitor per country (~8 once page IDs are saved)
Public ad libraries do not show spend or performance for commercial ads; TikTok's library covers EU/EEA, UK and Switzerland only.

creator-vetting-transcripts
Builds a one-page brief on a creator from their TikTok, Instagram and YouTube profiles, recent posts and video transcripts — posting rhythm, engagement per view, past sponsors and flags for review.
~25 credits per creator, three platforms, 10 posts and 3 transcripts each
Public, logged-out data only: no audience demographics or follower-quality scores, and transcripts need speech or captions.

competitor-content-digest
Collects competitors' latest posts on TikTok, Instagram, YouTube, X, Threads, LinkedIn and Facebook, ranks each post against that account's own baseline, and summarises the topics and formats they lean into.
~14 credits per competitor across all seven platforms
Logged-out listings are windows, not full feeds: LinkedIn shows about 10 recent posts and Facebook usually 1–2.

Skills call Captapi either through the hosted MCP server at https://api.captapi.com/mcp or over REST with CAPTAPI_API_KEY. The index agents read is at /.well-known/agent-skills/index.json, and the source lives in CDCStream/skills. See integrations for MCP setup.
