Do I need a YouTube developer account?

No. There is no YouTube app, OAuth flow or app review. One InsightSocial API key works for this endpoint and every other platform, and your first 10 calls priced at 100 credits or less are free.

What does one call return?

One call returns the data in the data object of the standard response envelope. Fields the platform did not provide are listed in unavailable, so a null there means unknown, not zero.

What happens if the account is private or nothing is found?

You get an error or an empty result, and it costs 0 credits. The API reads public YouTube data only, so private accounts and deleted content come back as not found rather than as partial data.

Can I call the YouTube Video Sponsors API from Claude, ChatGPT or Cursor?

Yes. Add the hosted MCP server at https://api.insightsocial.app/mcp to your AI app and sign in. The assistant finds this endpoint by name, shows its price and calls it with your credits.

GET /v1/youtube/video/sponsorsbeta

YouTube Video Sponsors API

Q: How much does the YouTube Video Sponsors API cost?

100 credits per successful call. A call that errors or finds nothing costs 0 credits, and an answer from the shared cache costs 2. Pro's 10,000 monthly credits cover about 100 calls at 100 credits each. Add dry_run=1 to see the price of a call without making it.

Returns whether a video carries a paid-promotion disclosure plus the brands likely sponsoring it, each with supporting evidence and a confidence score.
