TranscriptAPI.com
TranscriptAPI supplies YouTube text and discovery data for applications and assistant workflows. Its REST API and MCP interface cover transcript extraction, video search, channel search, channel listings, and playlist contents. A developer can use those operations to build a searchable video collection or collect the text needed for a separate analysis step.
Retrieve text and discover videos
Transcript output can include timestamps. The published response example includes language, video length, metadata, and timed text segments. Search endpoints return video details and pagination indicators, while channel and playlist operations help identify which videos to process.
Latest-upload checks are free of credit charges. That supports a selective workflow: check a channel for new items, then request transcripts only for videos relevant to your project. Search and list operations cost one credit per page, so a multi-page channel audit has a different budget from a single transcript request.
Connect through an API or MCP
The documentation hub links to endpoint references and integration guides. REST access uses an API key; MCP access lets a compatible assistant retrieve video material within its own conversation workflow. Transcript retrieval supplies source material, while summaries and comparisons depend on the application or assistant using that material.
The publisher's troubleshooting guide lists videos without available captions, private or age-restricted videos, region locks, and disabled embedding as possible reasons for missing transcripts. Check representative videos before building a pipeline around a particular channel. Avoid interpreting the site's broad access slogans as a guarantee that every video will be available.
Credits, rate limits, and top-ups
The homepage lists 100 free trial credits without a card. Monthly access is displayed at $5 with 1,000 monthly credits; annual access is $54 per year with the same monthly allowance. Published rate limits differ between those billing options.
Top-up credits require an active subscription. Their stated expiry is at least thirty days after purchase or the end of the current subscription period, whichever is later. Estimate consumption using successful requests and paginated results, then confirm the current rate limit and credit balance before a large extraction run.
