}Estimate the cost of an audio/video transcription job before submitting it.
Quote from one of three inputs:
Quoting from
This mode never fetches the source, so it cannot see which platform the media comes from. On models that price per platform — and on TikTok, which is priced from a fixed length-band card rather than by the hour — pass
Without
What
The quote is built in three steps, in this order:
source_url, source_file, or a bare duration_seconds.
Pass the same flags you will pass to the job.
ts_level: "word", diarize (which implies include_ts) and include_metadata can all raise the price. A quote that omits them comes in under what you are actually charged. include_ts on its own does not: segment-level timing is included in the base price.Quoting from duration_seconds
This mode never fetches the source, so it cannot see which platform the media comes from. On models that price per platform — and on TikTok, which is priced from a fixed length-band card rather than by the hour — pass platform alongside the duration:
curl -X POST "https://api.deapi.ai/api/v2/audio/transcriptions/price" \
-H "Authorization: Bearer $DEAPI_API_KEY" \
-H "Content-Type: application/json" \
-H "Accept: application/json" \
-d '{
"duration_seconds": 240,
"platform": "tiktok",
"model": "WhisperLargeV3Ct2",
"include_ts": true,
"ts_level": "word",
"include_metadata": true
}'
platform, the quote uses the model base rate with no duration-band rounding.
platform: "tiktok" is only valid with model: "WhisperLargeV3Ct2" — that is the only model that transcribes TikTok. Paired with any other model it is rejected with 422, the same way the job itself would be. See Audio/Video Transcription.What WhisperLargeV3Ct2 costs
The quote is built in three steps, in this order:
- Base amount — the TikTok length band for TikTok sources, otherwise the duration rate.
- Timestamps — segment-level timing is included in the base amount, so
include_ts: truewith the defaultts_level: "segment"does not change the quote. The base amount is multiplied by 1.5 only whents_levelisword, or whendiarizeis set — diarization carries the surcharge at any granularity,segmentincluded. - Metadata — if
include_metadatais set on a source that can return it, a flat0.005is added after the multiplication.
Authorizations
Sanctum personal access token, sent as Authorization: Bearer <token>. The token is opaque — it carries no claims and no embedded expiry, so do not attempt to decode it. Issue and revoke tokens from your account dashboard.
Headers
Available options:
application/json Body
multipart/form-data
Transcription price calculation parameters
- From a source URL
- From an uploaded file
- From a known duration
Exactly ONE input source per request — source_url, source_file or duration_seconds — hence the three variants below. They are mutually exclusive, not a menu of optional fields: sending two of them is a 422. platform belongs to the duration_seconds variant alone; with a URL or an upload the platform is derived from the source itself and passing it is rejected. Everything else (include_ts, ts_level, include_metadata, diarize, lang, model) applies to all three.
URL of video/audio to estimate price for. Mutually exclusive with source_file and duration_seconds; platform must NOT be sent with it, as it is derived from the URL.
Example:
"https://www.youtube.com/watch?v=jNQXAC9IVRw"
The model to use for transcription.
Example:
"WhisperLargeV3"
Should transcription include timestamps. Implied when diarize is true. Whether it raises the quote depends on ts_level — segment-level timing is included in the base price. Pass it exactly as you will pass it to POST /api/v2/audio/transcriptions.
Example:
false
Timestamp granularity. Validated against the model exactly as on POST /api/v2/audio/transcriptions, so a price quote is never returned for a combination the job request would reject. Granularity affects the price on models that price timestamps separately: segment is included in the base price, while word and char carry a surcharge.
Available options:
segment, word, char, null Example:
"word"
Whether the job will be asked to attach source metadata. Carries a flat surcharge on models that price it, so pass it exactly as you will pass it to POST /api/v2/audio/transcriptions or the quote will come in under the amount charged. The surcharge applies only to sources that can actually return metadata: uploads always return null and are never charged for it. Every recognised platform, YouTube included, does return metadata and is charged the surcharge.
Example:
false
Label each timed unit with a detected speaker. Requires a model that supports diarization. Implies include_ts and carries the timestamp surcharge at ANY granularity, including segment.
Example:
false
