Instagram Reels Transcript API

Beta

Returns the timed transcript of a public Instagram reel or video post. Instagram rarely exposes caption tracks to logged-out clients, so most transcripts are speech-to-text on the post's audio. Accepts reel, post, tv, instagr.am and share links or a raw shortcode; for carousels, img_index selects the item.

From 1 credit per request, up to 122 credits. Charged only for successful requests. Errors are free. The price depends on the source that produced the result, reported as meta.source; sources are tried cheapest first: Captions → Speech-to-text.

SourcePrice per successful requestPer 1,000 requests
Captions captions1 credit$0.75–$1.45
Speech-to-text asr2 credits + 2 per started minute of media
up to 122 credits (60 started minutes of media)
$1.50–$2.90 + $1.50–$2.90 per started minute of media

Example: a result from Speech-to-text asr with 3 started minutes of media costs 2 + 2 × 3 = 8 credits.

Balance, sources and what you were charged

Your balance must be at least 1 credit to start a request; with less, it is refused with insufficient_credits (HTTP 402) and costs nothing. Only that minimum is set aside when the request starts. One request costs at most 122 credits, but that amount is never locked up in advance: right before costlier work, SocialTap sets aside more of your balance, the exact price when the number of started minutes of media is known beforehand, otherwise as much as your balance allows (and the work is limited to what that pays for). It then charges the actual price and releases the rest. If the result would cost more than your balance covers, the request is refused with insufficient_credits as well, and costs nothing.

meta.sourceSourceWhat it means
captionsCaptionsThe platform's own caption track (uploaded or auto-generated).
asrSpeech-to-textTranscribed by SocialTap from the media's audio when the platform has no captions.

meta.credits_charged and the x-credits-charged header show what you paid. How credits work · Packs

A key starting with st_test_ gets recorded responses, free and the same every time (test mode). The recorded inputs return their recording; any other input returns the example above.
