Do I need a Facebook developer account?

No. There is no Facebook 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 transcript 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 Facebook data only, so private accounts and deleted content come back as not found rather than as partial data.

Can I call the Facebook Ad Library Ad Transcript 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/facebook/adlibrary/ad/transcript

Facebook Ad Library Ad Transcript API

When to use it

Use it when you need what an ad says out loud; adlibrary/ad returns the creative and spend but not the speech.

Parameters

Query parameters for GET /v1/facebook/adlibrary/ad/transcript. Send your key in the x-api-key header.

Name	Required	Description
id	One of id, url	Facebook Ad Library ad ID. Ad ids rotate as campaigns end, so take a current one from /v1/facebook/adlibrary/company/ads rather than reusing an old one.
url	One of url, id	Facebook Ad Library URL for the ad. A page URL is rejected with a 400.

Response fields

The same unified schema every platform returns, so code written for Facebook works on the other eight. A field the platform did not provide is null and listed in unavailable.

Field	Type	Notes
language	string \| null	The content's language as the platform states it, e.g. en, pt-BR. Detected languages come later (§7.1).
text	string \| null
segments	array \| null

Every field, error and example is in the Facebook Ad Library Ad Transcript API reference.
