TranscriptFetch is one API for getting text out of video and web content.

Send a URL from YouTube, TikTok, Instagram, X or Facebook and get back clean, timestamped text. Send any web page and get clean Markdown. One endpoint, one response shape, one API key.

The part that actually matters

Most short-form video has no caption track to download. TikTok's auto-captions are opt-in per upload, Instagram never publishes a downloadable track, and a large share of captions on both platforms are burned into the video frames where no parser can read them.

When there is no caption track, TranscriptFetch transcribes the audio instead. Same endpoint, same response, so your code never branches on which method produced the text.

What you get back

  • A joined text field for feeding a model or a search index
  • A segments array with per-cue start times and durations, so subtitles and jump-to-moment links are a formatting step rather than another integration
  • Consistent output whether the text came from captions or speech recognition

Built for pipelines and agents

  • MCP server so Claude, Cursor and other MCP clients can fetch transcripts as a tool mid-conversation
  • Python and JavaScript SDKs
  • Batch endpoint for up to 50 videos in a single call
  • Channel, playlist and keyword-search endpoints for ingesting at scale

Pricing

100 free credits on signup, no card required. One credit per successful response. Failed, blocked and empty results are never charged, which matters on short-form video where a meaningful share of any batch is music with no speech in it.

Possible disadvantages of Zephyr

  • Complexity
    Due to its modular and scalable nature, Zephyr can be complex to set up and configure, especially for beginners who may find the learning curve steep.
  • Limited Middleware
    While Zephyr supports a variety of hardware, its middleware offerings may not be as extensive or mature as those provided by more established OSes like FreeRTOS.
  • Documentation Gaps
    Although the community is active, there are areas where documentation could be more comprehensive and detailed, which can hinder quick adoption and troubleshooting.
  • Resource Intensive
    Given its wide range of features and capabilities, Zephyr can sometimes be more resource-intensive compared to more minimalist RTOS options, which might be a concern for extremely resource-constrained environments.
  • Vendor Lock-in Risk
    While Zephyr aims to be vendor-neutral, there can be dependencies on certain hardware platforms or vendors, which might lead to a form of vendor lock-in.

TranscriptFetch features and specs

Questions & Answers

As answered by people managing Zephyr and TranscriptFetch.

What makes your product unique?

TranscriptFetch's answer:

Most short-form video has no caption track to download. TikTokโ€™s auto-captions are opt-in per upload, Instagram never publishes a downloadable track, and many captions on both are burned into the video frames where no parser can read them. TranscriptFetch transcribes the audio when no caption track exists, on the same endpoint, with the same response shape. Your code never branches on which method produced the text. It also covers YouTube, TikTok, Instagram, X and Facebook plus any web page as clean Markdown, so a pipeline spanning several sources is one integration rather than five.

Why should a person choose your product over its competitors?

TranscriptFetch's answer:

Three reasons. Coverage: one API key and one response shape across five video platforms and the open web, instead of stitching together a library per platform. Reliability: requests run through rotating infrastructure, so code that works locally keeps working from a server, which is where most open-source approaches break. Billing that matches reality: one credit per successful response, with failed, blocked and empty results never charged. That last point matters on short-form video, where a meaningful share of any batch is music with no speech in it. There is also an MCP server, so AI agents can fetch transcripts as a tool without a custom integration.

How would you describe the primary audience of your product?

TranscriptFetch's answer:

Developers and technical teams building on video and web content. The common cases are RAG and retrieval pipelines that need video as text, AI agents that need to read a link mid-conversation, content teams repurposing short-form video at scale, and media monitoring and research tools. It is an API first, so the buyer is usually the person writing the integration rather than an end user. The free browser tools exist for one-off transcripts and for evaluating output quality before writing any code.

What's the story behind your product?

TranscriptFetch's answer:

It started with discovering there is no good way to get the text of a video. YouTubeโ€™s official Data API will confirm a caption track exists and then refuse to hand it over, because captions.download requires the video ownerโ€™s OAuth token. The popular open-source libraries work until you deploy them, at which point platforms start refusing datacenter IPs. And YouTube is the easy case: TikTok and Instagram publish no caption file at all. Every workaround solved one platform, worked locally, and broke in production. TranscriptFetch is the version that handles the failure cases as first-class behaviour rather than edge cases.

Which are the primary technologies used for building your product?

TranscriptFetch's answer:

Next.js with TypeScript and Tailwind on the front end and API layer, Clerk for auth with SHA-256 hashed API keys, Neon Postgres with Drizzle ORM, Redis for caching, and Stripe for billing. The extraction layer is a Python and FastAPI service. Speech-to-text uses Whisper-class models. The MCP server is published in the official Model Context Protocol registry with a DNS-verified namespace.

Zephyr mentions (11)

  • A Web based Broadcast Assistant
    Combining the Zephyr RTOS stack, running on an affordable nRF52840 Dongle with the power of modern web technologies turned out quite well and it has also allowed us to experiment with multiple subgroups, supported by the specs, but not yet by many devices in the market (at the time of writing at least - be sure to keep an eye out for that!). - Source: dev.to / over 1 year ago
  • Auracast and multiple subgroups
    Also, it's really great to see that the RFcreations mini-moreph and blueSpy software was able to capture and render this slightly more advanced source and that it was possible to build using Zephyr RTOS and the nRF52840 Dongle. - Source: dev.to / over 1 year ago
  • A simple Broadcast Audio Source
    The Zephyr RTOS contains some great Bluetooth LE Audio related samples. One of them is the Basic Audio Profile (BAP) Broadcast Source sample. - Source: dev.to / over 1 year ago
  • Capturing the perfect (radio) wave
    I thought about what would be a good first capture, and remembered, I recently made a very simple Bluetooth Low Energy demo using Zephyr and Web, covered in an earlier post. - Source: dev.to / almost 2 years ago
  • It's 2023 why embedded development is so cumbersome?(rant)
    Check out Zephyr OS and Platform IO. Zephyr is part of the Linux foundation and has similarities to Linux with how it performs hardware abstraction (device tree). Platform IO integrates with other frameworks including mbed and Arduino. Source: almost 3 years ago
