Newest indexed videos of a channel
GET /v1/channels/{channel_id}/videos
The indexed videos of a YouTube channel, newest first, each with its video_id, title, publish date, duration, view count, and watch_url on arcmira.com. Pass next_cursor as cursor to continue. The signed token binds the route, filters, caller and visibility; invalid or old tokens return invalid_cursor. A first-page media ID fence excludes later insertions, including old-date backfills; edits and deletions to existing videos remain live. Call it for the latest or most recent episode of a show, or to list what a show published in a window, then pass a video_id to GET /v1/mentions/counts video_ids for what that episode mentions or to GET /v1/transcripts/{video_id} to read it. indexed_through is the newest date we hold for the channel. An empty list means nothing is indexed; channel backfill is not available yet. Uses 4 credits per video returned past the first 5. Every gate is a typed error whose error.unlock.url names the plan that lifts it; pass src=mcp-tool only from the Arcmira MCP server.
Parameters
| Name | Location | Description |
|---|
| channel_id (required) | path | YouTube channel id, the UC... form. |
| limit | query | Videos to return, 1 to 25, newest first. Default 10. Pass 1 for the latest episode. |
| cursor | query | Opaque continuation from next_cursor. Bound to the channel, filters, caller, and visibility; limit may change between pages. Invalid or old tokens return invalid_cursor. |
| after | query | Only media published at or after this instant. An ISO 8601 date (2026-09-01) or datetime with offset (2026-09-01T00:00:00Z), read in UTC. The window is half-open: after is inclusive, before is exclusive. |
| before | query | Only media published before this instant, so before=2026-09-02 includes all of 2026-09-01. An ISO 8601 date (2026-09-01) or datetime with offset (2026-09-01T00:00:00Z), read in UTC. The window is half-open: after is inclusive, before is exclusive. |
| src | query | The surface making this call. The Arcmira MCP server sends mcp-tool so every unlock link in a gate attributes to the directory install. Omit from your own client. |
