Metadata Provider (metadata_provider)

Before a new series rule is saved, AB selects a metadata source with the "parser" value of the RSS subscription. The source completes the official title, season, year and poster. mikan and tmdb are built in. @provider(points.METADATA_PROVIDER, id=...) adds a new value. The "parser" list shows it when the user adds a subscription.

    async def enrich(self, request: MetadataRequest) -> Metadata | None:
        info = await search(request.current.official_title)  # your own code
        if info is None:
            return None  # no change
        return replace(request.current, official_title=info.name, poster_link=info.cover)

    @provider(points.METADATA_PROVIDER, id="bangumi-tv")

• request.kind separates a series (bangumi) from a movie (movie). request.torrent.homepage is the detail page of the torrent. request.language is the language setting.
• Return a complete new Metadata, usually changed from request.current. None means no change.
• On a failure or a timeout AB keeps the old value, and the failure counts toward the breaker.
