Questions
Which errors can it return?
invalid_params (do not retry), unsupported_url (do not retry), not_found (do not retry), transcript_unavailable (do not retry). Account and platform errors from the errors list can also happen. A failure always costs 0 credits.
Is there an SDK call for it?
The Python client has client.facebook.ad_library_ad_transcript(...) and the TypeScript client client.facebook.adLibraryAdTranscript(). Both return the same envelope as the HTTP API. Install them from PyPI (socialscrape-sdk) or npm (socialscrape); plain HTTP works in any language.
Can an AI agent call it?
Yes. The MCP server, which you run on your own machine, reaches every built endpoint, with the same prices.
