YouTube post API

YouTube post data in one REST call — normalized to the stable JSON schema shared across every FetchPI platform.

1 documented endpoints
GET /v1/youtube/posts/{id}

Contract summary (English): Get a normalized YouTube video (capability youtube.post)

Normalized response entity: youtube/post
capability: youtube.post

Every response also carries freshness (cache / default / live) and billing metadata.

Use cases

Feed content-analysis pipelines with structured {{platform}} posts: text, metrics, timestamps and media references.
Power moderation, research and monitoring workflows that need the original content plus engagement counts.
Archive {{platform}} content as stable, normalized JSON instead of brittle page scraping.

Response fields

YouTube Video Post (normalized)

Normalized YouTube video. Provider-private fields MUST NOT appear. Metric names are frozen (views/likes/comments — 观播放/赞/评); hidden counts normalize to 0. `title` is the platform extension field (the video headline — text carries the description). author and created_at are nullable: search/list cards may omit the channel block and the web surface sometimes ships only relative publish-time text ("2 weeks ago" — lossy, never fabricated into an instant; a present-but-unparsable timestamp still fails).

Field	Type	Required	Description
id	string	Required	Video id.
platform	"youtube"	Required	—
type	"post"	Required	—
author.id	string	Required	Channel id (UC…).
author.username	string	Required	Channel @handle; the channel id when no handle exists.
