## MCP tools (1)

### `get_youtube_channel_stats` (~488 tokens)

Get YouTube Channel Stats

Resolve a company domain, or a YouTube handle, to that company's YouTube channel. Returns the subscriber count, the stable UC channel id, channel name, creation date and description, as one flat Clay ready row. Subscriber counts are rounded by YouTube above roughly a thousand subscribers, on the page and in its official API alike, and the row flags that. Optional transcript pulling is available and is CURRENTLY GATED by YouTube: the caption track list is readable and the caption content endpoint returns an empty body without a proof of origin token, which the row reports as not_extractable rather than as a video having no captions. No API key needed. Read only; requires an APIFY_TOKEN and consumes Apify credits per call.

Input parameters:

- `company_domain` (string): Bare company domain, for example shopify.com. Supply this or a handle. With a domain the actor runs full discovery; with a handle it skips straight to the fetch.
- `company_name` (string): Optional. Improves search accuracy and is what the identity gate checks a discovered profile against, so supplying it reduces wrong matches.
- `handle` (string): Optional. A YouTube handle such as @shopify, or a full channel URL. Supplying it skips discovery and goes straight to the channel.
- `includeFollowerCounts` (boolean): When "true" (default) the profile page is fetched and the counts are extracted. Set "false" to resolve the profile URL only, which is cheaper and needs no proxy. Sent as a string for Clay compatibili…
- `includeTranscripts` (boolean): When "true", full timestamped transcripts are pulled for the most recent videos on the channel and returned as one row per video. Default is "false" because transcripts are the expensive half of this…
- `skipCache` (boolean): When "false" (default) a successful lookup is cached for seven days and reused. Set "true" to force a fresh fetch. Sent as a string for Clay compatibility.
- `transcriptVideoCount` (string): How many of the channel's most recent videos to pull transcripts for, when transcripts are on. Default 5. Each video is one extra fetch and one extra billable transcript event, so this is the dial th…
