Transcript API pricing, compared by volume
Plan names and credit rules make transcript APIs hard to compare. Here is what each one costs for the same number of transcripts a month.

Monthly cost by volume
| Transcripts / month | Transkrio | Supadata | TranscriptAPI |
|---|---|---|---|
| 100 | Free (once) | Free (every month) | Free (once) |
| 1,000 | $9, or a $10 pack of 2,000 that never expires | $17 | $5 |
| 3,000 | $9 | $17 | $10 ($5 + 2 top-ups) |
| 15,000 | $29 | $47 (30,000 plan) | $40 ($5 + 14 top-ups) |
| 75,000 | $99 | $297 (300,000 plan) | ~$190 ($5 + top-ups) |
TranscriptAPI top-ups are $2.50 per 1,000 ($1.50 on annual billing), so its cost grows in a straight line. Supadata jumps between plan sizes. Transkrio's plans are 3,000, 15,000 and 75,000 credits.
The rules that change the real price
| Transkrio | Supadata | TranscriptAPI | |
|---|---|---|---|
| Failed requests | Free | Not stated | Only successful requests charged |
| Unused credits | Roll over, up to 2x the plan | Expire monthly | Top-ups last 30+ days |
| Videos without captions | 1 credit / minute | 2 credits / minute | Not offered |
| Platforms | YouTube, TikTok, Reels, podcasts | YouTube, TikTok, Instagram, X, Facebook, files | YouTube |
If your list of URLs includes private or deleted videos, free failures matter. If your usage swings month to month, rollover matters. If you transcribe TikToks, Reels or podcasts without captions, the per-minute rate matters most: a 30-minute episode is 30 credits on Transkrio and 60 on Supadata.
What about doing it yourself?
The open-source youtube-transcript-api and yt-dlp are free, but on cloud servers YouTube blocks them and you need rotating residential proxies billed by bandwidth, plus retries and upkeep. See library vs API and yt-dlp vs API.
