Facebook Ad Library ad transcript API reference

GET /v1/facebook/ad-library/ad/transcript

Transcript of a video ad. Ad Library videos carry no caption tracks, so this is always AI transcription of the audio, billed by the length of the audio. An ad with no video answers an unbilled error.

Cost: 1 credit for captions; AI transcription 1 up to 2 minutes, then 5 per started minute of the whole video
Cache: Results are kept up to 30 days; send max_age_days to reuse them for free.
Timeout: A request still running after about 25 seconds answers 202 with a job to poll (Batch and jobs).

Parameters#

Name	Type	Required	Description
`id`	string	one of	Ad id in the library. Also accepted as `ad_id`, `adId`.
`url`	URL	one of	Ad Library URL (facebook.com/ads/library/?id=...). Accepted hosts: `facebook.com`.
`allow_long_transcription`	boolean	no	Transcribe audio past 2 minutes with AI, at 5 credits per started minute of the whole video. Without it a longer video answers transcript_unavailable, which is free. Default `false`. Also accepted as `allowLongTranscription`.

Send at least one of id, url. If you send several, the first listed is used and the rest are ignored.

Every request also accepts:

trim: true for a smaller response without null fields and extra.
raw: true to also get the platform's original object as raw.
max_age_days: accept a cached result up to this many days old, for 0 credits (Caching).

See Data models for every field. The envelope around data is described in Responses.

Errors#

Failures are free: credits_charged is 0. Branch on error.code, never on the message.

Code	HTTP	Retry	Meaning
`invalid_params`	400	no	A parameter is missing, unknown or has the wrong type.
`unsupported_url`	400	no	The URL is not one this endpoint accepts (wrong platform or form).
`not_found`	404	no	The platform says this profile, post or item does not exist.
`transcript_unavailable`	404	no	No captions exist and AI transcription is not possible for this media.

Every request can also fail with the account and platform errors listed on the Errors page.
