YouTube transcript API comparison: seven options

Three answers cover most of this market. If you need text from videos that have no captions at all, use Supadata — it falls back to speech recognition and we do not. If you are running a script on your own machine, use the free youtube-transcript-api Python library and pay nothing. If you are pulling thousands of transcripts from a server and the failures are costing you more than the transcripts, a hosted option is worth its price, and ours is one of them.

Everything below is the detail behind those three sentences. Prices were checked on 3 September 2026 and move often enough that you should confirm before committing.

Which one should you pick?

Pick on the constraint that is actually hurting you, not on the price per thousand. The price spread across this market is roughly eight-fold, but the gap between “returns a transcript” and “returns nothing from your production host” is total.

The thing we do not do

We have no speech-to-text fallback. If a video has no caption track, we return a structured result saying so, and that is the end of it. Supadata transcribes the audio and hands you text anyway.

This is the one axis where a competitor is clearly ahead of us, and it is not a small one. Music channels, short clips, poor-audio uploads and several languages routinely have no automatic captions. On a set like that, an ASR fallback is the difference between a usable dataset and a mostly empty one.

Where it does not matter: talks, lectures, podcasts, interviews and news, which almost always carry an automatic track. On those sets ASR is paying for a path you never take, and the caption text is what YouTube itself serves.

Measure the caption rate on a sample of your own videos before choosing. If a meaningful share come back with no captions, that decides it, and it does not decide in our favour.

What the market charges

Between $0.99 and $7.99 per 1,000 requests across the vendors we surveyed on 3 September 2026. Most publish tiered plans rather than a single rate, so the headline number is usually the highest tier’s price and volume pulls it down.

We sit above the bottom of the range. The honest reason to pay it is the billing shape rather than the rate: nothing is charged for a video that returns no transcript, so a batch full of caption-free videos costs you the failures at zero rather than at list price. If your video sets are clean, a cheaper vendor is cheaper.

Where the free Python library is the right answer

Whenever it works. youtube-transcript-api is maintained, widely used and free, and from a home or office connection it returns transcripts perfectly well. Paying for a hosted API to run a script on your laptop is spending money to solve a problem you do not have.

It stops being the right answer at one specific moment: when you deploy it. On a cloud host’s own IP address it returns close to nothing, because the block is applied on address reputation before anything about your code matters. We measured 0 of 12 from an unproxied cloud host on 2 September 2026.

That single failure is what the whole hosted market is selling against. There is a longer treatment in our comparison against the library itself, including the case for keeping it and adding a proxy rather than switching vendor.

What the comparison tables do not tell you

Four things decide the outcome more often than the feature grid does.

1. Egress. Every hosted vendor is buying residential addresses. That is the actual product, and none of them will describe how they route.
2. Failure billing. A video with no captions still costs a request at most vendors. On a set with a 20% caption-free rate, that is 20% of your bill for nothing.
3. Batch shape. Some APIs are one video per call, which turns 5,000 transcripts into 5,000 round trips and your own retry logic. Bulk-first tools take the list.
4. What breaks when YouTube changes. Every option on this page depends on undocumented behaviour. The question is not whether it breaks, but who fixes it and how fast. With the library, the answer is a maintainer and a queue of issues. With a vendor, it is their pager.

Limitations

We are one of the options listed. Read this page knowing that. The check we would apply to anyone else applies here: verify the claims on a sample of your own videos before believing them.

Prices move. The $0.99–$7.99 range was surveyed on 3 September 2026 from published pricing pages. Tiers, free allowances and overage rules changed on at least two vendors during the survey period, and per-vendor rates are omitted above for that reason.

We have not benchmarked competitors’ reliability. Running a fair reliability test against another vendor’s paid API means paying for it and controlling for their retry behaviour, which we have not done. The measured numbers on this site describe our own extraction only, and no competitor’s failure rate is asserted anywhere here.

No ASR fallback from us. Restating it because it is the load-bearing weakness on this page: if your videos lack captions, we return nothing usable and Supadata does not.

YouTube only. No TikTok, no Instagram, no podcast platforms. If you need multi-platform coverage in one integration, this is the wrong tool regardless of price.

Feature sets for the smaller vendors are summarised, not audited. ScrapeCreators, SocialKit, youtube-transcript.io, EasyTranscriber and TranscriptFetch are grouped above because we have not tested them individually.

FAQ

What is the best YouTube transcript API?

There is no single answer, and any page giving you one is selling something. For videos without captions, Supadata, because it transcribes the audio. For local scripts, the free Python library. For bulk extraction from a server, any hosted API with residential egress — compare them on failure billing and batch shape rather than on the headline rate.

How much does a YouTube transcript API cost?

Between roughly $0.99 and $7.99 per 1,000 requests as of 3 September 2026, depending on vendor and tier. Ours is $5 per 1,000 transcripts with no charge for videos that return nothing. The effective cost depends heavily on how many of your videos have no captions, because most vendors bill those as requests.

Can any API get a transcript for a video with no captions?

Only one that runs speech recognition over the audio. Supadata does this. Caption-based tools, ours included, cannot — there is no caption track to fetch. If a vendor claims full coverage without mentioning ASR, ask what it returns for a music video.

Why not use the free youtube-transcript-api library?

Use it, until you deploy it. The library is fine on a residential connection and free. It fails on cloud host addresses because YouTube blocks those ranges, which is a network problem rather than a bug in the library.

Do these APIs work for TikTok and Instagram too?

Supadata covers YouTube, TikTok and Instagram in one API. Most of the others, ours included, are YouTube only. If you need more than one platform, that consolidation is worth more than a lower per-thousand rate.

Are transcripts from these APIs the same text?

For caption-based tools, yes in substance — everyone is retrieving the same track YouTube serves, so differences are in formatting, timing granularity and how missing captions are reported rather than in the words. ASR output is different text entirely, generated from the audio, with its own error profile.

What should I test before committing to a vendor?

Take 100 of your own video IDs, not a curated sample, and run them through a trial. Count three things: how many returned text, how many were charged for returning nothing, and how many failed for reasons that look like blocking. Those three numbers decide it more reliably than any comparison page, this one included.
