Instagram Reels Transcript API

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.

data follows the shared Transcript schema, identical on every platform.

data.urlstring (uri)Canonical URL of the post.

Pricing

You pay only for successful requests. The price depends on which source produced the result, reported as meta.source; sources are tried cheapest first, in the order Captions → Speech-to-text.

SourcePrice per successful requestPer 1,000 requests
Captions captions1 credit$0.50–$0.80
Speech-to-text asr2 credits + 2 per started minute of media
up to 122 credits (60 started minutes of media)
$1.00–$1.60 + $1.00–$1.60 per started minute of media
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.

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

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.

Errors

Errors cost nothing. Codes marked “Yes, later” under Retry can succeed on a later attempt; the others return the same answer every time.

CodeHTTPRetryMeaningWhat to do
invalid_input400NoThe request parameters are missing or malformed, or the URL is not a supported link for this endpoint.Fix the parameter named in the message; see the endpoint's accepted URL forms.
unauthorized401NoThe x-api-key header is missing, unknown or revoked.Send a valid API key in the x-api-key header.
insufficient_credits402NoThe account does not have enough credits for this request.Buy a credit pack, then repeat the request.
rate_limited429Yes, laterThe account exceeded its runaway-protection ceiling: plans do not limit request rate, but a high per-account safety ceiling stops broken client loops. Support raises it on request.Wait for the number of seconds in the retry-after header, then retry; ask support to raise the ceiling if your sustained traffic needs more.
not_found404NoThe item does not exist or was deleted.Check the URL or ID; do not retry.
private_or_unavailable403NoThe item exists but is private, age- or region-gated, or requires a login to view.Only public items can be fetched; do not retry.
no_transcript404NoThe media exists but has no transcript: no caption track and no speech to transcribe.Do not retry; try another language with lang if the platform offers one.
upstream_blocked503Yes, laterThe platform refused every attempt.Retry later with backoff; failed requests are free.
upstream_error502Yes, laterThe platform failed or returned something unexpected.Retry with backoff; failed requests are free.
overloaded503Yes, laterEvery SocialTap engine instance that could serve the request was at capacity; no upstream work was done. Capacity grows with traffic, so this is brief.Retry after the number of seconds in the retry-after header; failed requests are free.
internal500Yes, laterUnexpected SocialTap error.Retry with backoff; contact support with the request_id if it persists.

not_found, private_or_unavailable and no_transcript are item-level: the request was fine, the item can't be returned.
