Fetch venue-native metadata for one event (Kalshi only; not router).

GET

/api/{exchange}/fetchEventMetadata

curl --request GET \
  --url 'https://data.predictefy.com/api/example/fetchEventMetadata?eventId=example' \
  --header 'Authorization: Bearer <token>'

• Canonical reads origin. Execution operations declare their isolated origin per operation.

Fetches Kalshi's anonymous GET /trade-api/v2/events/{event_ticker}/metadata endpoint. The venue body is passed through unchanged under data.raw; no undocumented metadata fields are normalized. Other known venues answer 501 NOT_SUPPORTED.
