Agent workflows

Use YouTube records as evidence, not glue code.

UnifAPI keeps the public YouTube surface discoverable through MCP and callable over HTTP. Agents can inspect the schema, fetch only the records needed for the task, and return the result with request, pagination, and billing metadata intact.

Search YouTube, fetch channel and video metadata, browse related videos, and inspect trending content from one API surface.

Support creator research, channel benchmarking, market monitoring, and topic discovery Skills with live video and channel records.

Resolve channel identifiers and video ids into canonical data that can be joined with TikTok, X, Reddit, LinkedIn, or Instagram evidence.
